Top Reasons to Follow the Recommended Vaccine Schedule

Every once in a while we see a child whose school nurse says the child’s vaccines didn’t count and need to be repeated. This can be due to many things, usually inappropriate timing of vaccines. Some electronic health records now have intelligent vaccine recommendation abilities. These smart vaccine logic systems are catching kids who had incorrect spacing before this technology. Staying on the routine vaccine schedule and keeping all records in one place can help avoid extra doses due to inappropriately spaced vaccines.

One thing to remember if your child needs extra doses: you don’t need to worry. They’re safe!

What’s in this post?

First you’ll need to understand about the different types of vaccines to know why they are scheduled like they are. Some are given in a series to boost the initial response, but others need to be repeated to cover those who weren’t protected with a first dose.

Then we’ll do a quick review of the risk of the diseases to remind us why we vaccinate in the first place.

Hopefully after learning some basics, you’ll see why the timing of vaccines is so important and why we should all follow the recommended vaccine schedule.

What’s not in this post?

If you want to know what to do if a recommended vaccine has been delayed, see What happens if a vaccine booster is delayed?

Dr. Vincent Iannelli has a list that includes some issues not discussed in this post, such as improper storage.

How vaccines work

Vaccines are made in different ways and the body responds to them in different ways.

Live attenuated vaccines

Live attenuated vaccines are made from weakened virus that teaches the body to recognize the real virus but doesn’t cause the symptoms of the virus in healthy people.

Those with weak immune systems should talk to their physician before receiving a live virus vaccine. The amount of immune compromise and specific vaccine must be taken into account on an individual basis.

It’s usually okay to be vaccinated with a live virus vaccine if you’ll be around an immunocompromised person, but again, let your physician know the risk of exposure.

Examples of live virus vaccine:
  • rotavirus
  • measles
  • mumps
  • rubella
  • varicella
  • nasal flu vaccine (NOT the injectable flu vaccine)

Many people respond sufficiently to the first dose of these, but repeat doses are given to help those who missed the response the first time.

The second dose doesn’t boost the first, but it gives a person a second chance at making immunity.

Spacing between doses:

Because of the way these vaccines work, they must follow special separation rules. More than one live virus vaccine can be given on the same day, but they cannot be given on separate days that are closer than 4 weeks apart.

If one live virus vaccine is given, you must wait a minimum of 28 days to give another. If they’re given too close together, the body doesn’t make immunity as well to the second one given. This second vaccine wouldn’t count.

As an example, if the FluMist (nasal flu vaccine) is given on January 1 and the Varicella vaccine is given January 15 of the same year, the Varicella vaccine will not count and must be repeated.

Live virus vaccines are the only vaccines that are subject to this 28 day rule. If another vaccine type is needed, it is okay to give in a shorter time frame.

For example, if a child has the MMR at his 4 year well visit, it is okay to do an injectable flu vaccine at a flu clinic later that same month. (Note: the nasal flu vaccine is a live virus vaccine, so it is NOT okay to give the FluMist within the month before or after the MMR.)

If there is less than 28 days between live virus vaccines, the one that was given second must be repeated.

I see this quite frequently in kids who move to the US from other countries. It seems quite common elsewhere for kids to get the varicella (chicken pox) vaccine about 2 weeks after the MMR. When this happens, another varicella vaccine is needed.

Live virus vaccines aren’t recommended under 1 year… usually

Many parents worry that we don’t give live virus vaccines to infants because they’re less safe, but that’s not why at all.

Maternal antibodies (fighter cells from mom that got into baby during pregnancy) can inhibit the body from being able to build its own antibodies well against a vaccine.

Maternal antibodies are good because as long as they’re in the baby’s body, they fight off germs and protect the infant! They tend to hang around for the first 6-12 months of life.

If a disease has a low incidence, it is acceptable to let the maternal antibodies do their job for the first year.

By the first birthday most maternal antibodies have left the infant, so a vaccine can be used to build the baby’s immunity.

International travel increases risks

If there is a high risk of exposure it is recommended to give the vaccine as early as 6 months in case the maternal antibodies are already too low for infant protection. Many parts of the world have high measles rates so fit into this recommendation.

If the antibody levels are still high, the vaccine won’t work, but the baby should still be protected against the disease from mom’s antibodies.

At some point the maternal antibodies go away, we just don’t know when exactly, so the baby who gets the MMR early needs another dose after his first birthday to be sure he’s making his own antibodies once mom’s go away. This dose after the birthday is the first that “counts” toward the two MMRs that are needed.

The next dose of MMR can be anytime at least 28 days after the first counted dose, but we traditionally give it between 4-6 years with the kindergarten shots.

Yes, I realize there are some measles outbreaks in the US, but the experts have not said to start giving that extra dose to babies who are staying here yet. If you’re worried, talk to your doctor.

Inactivated virus vaccines

Inactivated virus vaccines are made by killing the virus and using it to make the vaccine.

They aren’t as effective as live virus vaccines, so several doses are needed to build immunity to these.

Examples of inactivated virus vaccines:
  • inactivated polio vaccine
  • injectable flu vaccines
  • hepatitis A vaccine

Subunit, recombinant, polysaccharide, and conjugate vaccines

Subunit, recombinant, polysaccharide, and conjugate vaccines use specific pieces of a virus or bacteria to make a vaccine.

Because these vaccines use only specific antigens, they give a very strong immune response that’s specific to the infectious particle and side effects are less common.

This type of vaccine is safe for nearly everyone, including people with weak immune systems.

One limitation of these vaccines is that you may need booster shots to get ongoing protection against diseases.

Subunit, recombinant, polysaccharide, and conjugate vaccines include:
  • Hib (Haemophilus influenzae type b) – not related to influenza vaccine at all
  • Hepatitis B
  • HPV
  • whooping cough
  • pneumoccal disease
  • meningococcal disease

Toxoid vaccines

Toxoid vaccines prevent diseases caused by bacteria that produce toxins in the body.

The toxins are weakened into toxoids so they cannot cause illness and are used to make the vaccine.

When the immune system receives a vaccine containing a toxoid, it learns how to fight off the natural toxin.

Example of toxoid vaccine:
  • diphtheria and tetanus portions of the DTaP vaccine

Several shots are needed to build and continue immunity over time.

Passive immunization

Passive immunization is a bit different than any of the above.

Either catching a disease or getting any of the above vaccines stimulates your immune system to make memory cells to fight of that specific germ if it comes in contact with it.

Passive immunity results when a person is given someone else’s antibodies.

The protection offered by passive immunization is short-lived, usually lasting only a few weeks or months, but it helps protect right away.

Example of a passive vaccine:
  • Synagis (RSV) vaccine

Why are vaccines repeatedly given?

Vaccines interact with the T and B cells of our immune system to make memory cells.

If you want to learn more, see How Vaccines Work. It’s a really cool slide show from The College of Physicians of Philadelphia.

Some vaccines need several doses to help the body develop a strong immunity against the germs. Later boosters are required to maintain that level of protection.

Other vaccines require more than one dose to insure that most people develop the protection.

Age at time of vaccine matters

The CDC Immunization schedule allows for age ranges for many vaccines to be given. Many states allow a grace period around those ages, but not all do.

Some vaccines have been shown to work best at certain ages. Our vaccine schedule reflects the best ages to give vaccines so that they are safe and effective.

If a child receives a vaccine within the grace period of their current state, it might “count.” But if that child moves to another state, the vaccine might not count per the new state’s laws.

My office only gives the routine MMR, Varicella, and Hepatitis A vaccines on or after the first birthday to help prevent a child from moving to a location that does not have a grace period. This is despite the fact that Kansas does have a 4 day grace period.

We will give the MMR earlier under certain circumstances as discussed above, but it does not count toward the two needed after the 1st birthday.

Spacing matters

Many vaccines need to be separated by a minimum timeframe, often 4 weeks, but sometimes longer. The Hepatitis A vaccine has a minimum timeframe of 6 months between doses, for example.

If the vaccine doses are not separated by a minimum time, one or more will need to be repeated.

For spacing rules, see the CDC vaccine schedule at the bottom of this post. Click on “footnotes” to see the details for each vaccine.

Why not space them out further?

Many parents have come to believe the “too many too soon” theory. They believe this despite the overwhelming evidence that vaccines are safe and effective when given according to the CDC schedule.

The risks to waiting to give vaccines are many.

Increasing vaccine preventable disease rates

Young adults of today have grown up without seeing the suffering of vaccine preventable diseases. But we’re seeing an increase in these diseases where vaccine rates have fallen.

Infants who aren’t vaccinated are at risk of diseases that can lead to death. They are among the most vulnerable and need protection.

More trips = more exposure

Not only are underimmunized children more at risk for vaccine preventable diseases, but bringing them to a clinic more frequently to do one vaccine a time increases risk. Each time they visit the clinic, they’re exposed to all the common viruses. Why risk bringing them back again and again to get more exposures?

Giving the vaccines together has been shown to be safe and effective.

More visits = more stress

There are studies that show less overall stress to the body if vaccines are given together.

Studies have shown that the first injection causes a stress response measured by elevated heart rate, blood pressure, cortisol levels, and cry. Subsequent injections given at the same time do not increase as significantly the stress when compared to returning on different days to get further injections.

The immune system can handle it

Are you worried about “too many too soon” and that vaccines will overwhelm the immune system? Stop worrying. These fears are simply unfounded.

As Paul Offit summarized in Addressing Parents’ Concerns: Do Multiple Vaccines Overwhelm or Weaken the Infant’s Immune System?:

Current studies do not support the hypothesis that multiple vaccines overwhelm, weaken, or “use up” the immune system. On the contrary, young infants have an enormous capacity to respond to multiple vaccines, as well as to the many other challenges present in the environment. By providing protection against a number of bacterial and viral pathogens, vaccines prevent the “weakening” of the immune system and consequent secondary bacterial infections occasionally caused by natural infection.

Keep your child’s vaccine record handy

I see many kids who transfer to my office but I don’t have access to their vaccine records at the time of the visit. This makes it difficult to know which (if any) vaccines are needed.

Hopefully as we use Electronic Health Records with portals and vaccine registry databases more this will become a non-issue. At this time it’s still a problem.

This is one of the many reasons I prefer for all vaccines to be given at the same clinic. If you’re changing primary care providers, be sure records are transferred before your first visit.

Flu vaccines are especially troublesome.

Flu vaccines are commonly given in many locations: your primary care provider (PCP) office, a parent’s workplace, a local pharmacy, at a school flu vaccine drive. They need to be repeated yearly, so it’s easy to forget if each of your kids has had it this year.

It’s common for one parent to not know if their child got a flu vaccine already this season. That leads to a missed opportunity or vaccines given unnecessarily.

I have seen a few kids who couldn’t get their kindergarten vaccines at their well visit because they recently had a FluMist elsewhere. That requires another trip to the office for the family.

I have seen a few kids who did get the kindergarten vaccines inappropriately because the parent didn’t realize the other parent had taken them for a FluMist elsewhere. They needed to repeat the MMR and varicella vaccines, which didn’t make the kids happy!

FluMist is coming back to the US for the 2018-2019 flu vaccine season. It is not the preferred vaccine by many experts due to continued concerns about its effectiveness, but it will be preferred by many kids who hate needles. If your kids worry about shots, learn how to make them less painful.

Be sure to keep track if your kids get a FluMist – especially if they’re getting kindergarten vaccines around the same time!

Measles Outbreaks: What can you do to protect your family?

Any area can be affected by measles. My county is in the middle of an measles outbreak right now. This is despite relatively high MMR vaccine rates above 95% for at least 1 MMR by 3 years of age. There are a lot of questions about measles outbreaks, so I thought I’d tackle a few. Like most pediatricians, I’ve never seen measles and I hope to not miss it if I do. We all need to be aware of its symptoms so we can recognize it when we see it!

What is measles?

Measles is a viral illness that includes fever, cough, fatigue, red eyes, and a characteristic rash. The rash spreads from head to trunk to lower extremities.

Measles is usually a mild or moderately severe illness. It can lead to pneumonia, encephalitis, and even death (risk of 2-3 per 1000).

One rare complication of measles infection that occurs many years after the illness appears to resolve is subacute sclerosing panencephalitis (SSPE). It is a fatal disease of the central nervous system that usually develops 7–10 years after infection.

 

 

 

Koplik spots, measles 6111 lores
Source: https://commons.wikimedia.org/wiki/File%3AKoplik_spots%2C_measles_6111_lores.jpg
Koplik spots are a specific rash seen in the inner cheek. Koplik spots are visible from 1 – 2 days before the measles rash and disappears to 1 – 2 days later. They look like white spots with a blue center on the bright red background of the cheek. They can easily be missed because they are not present for long, but if seen are classic for measles.

What is the timeline of symptoms after exposure?

Measles is highly infectious. It is primarily transmitted by large respiratory droplets in the air, so handwashing doesn’t help prevent exposure.

An area remains at risk for up to 2 hours after a person with measles was there. This is why it is IMPERATIVE that you should not leave your house if you suspect you have measles until you have spoken with the health department or your physician. DO NOT go to a walk in clinic or your doctor’s office unannounced. You will need to make arrangements to meet someone outside and wear a mask into the building. You will be put in a special negative pressure room, which is not available in most clinics.

More than 90% of susceptible people develop measles when they’re exposed.

The average incubation period for measles is 11–12 days. It takes 7–21 days for the rash to show. It is due to this long time for the characteristic rash that susceptible people who were exposed are put in isolation for up to 21 days.

Most people are contagious from about 4 days before they show the rash until 4 days after the rash develops. If a person has measles and the rash resolves, they can leave isolation when cleared by their physician and/or the health department.

What is a measles outbreak?

Measles outbreaks are defined as 3 or more measles cases linked in time and space.

How do outbreaks start?

I know the big question on everyone’s mind during an outbreak is, “Where did it start?”

Often an unimmunized traveler brings the measles virus into the US. Countries in Europe, Africa, Asia, and the Pacific continue to have outbreaks. Travelers who visit those countries can return to the US and share the virus for a few days before symptoms are recognized. Anyone who was in the same area as an infected person for up to 2 hours after that person left the area could be exposed.

In case you’ve heard that vaccines can lead to outbreaks: that’s not the case. Measles shedding from the MMR does not cause disease.

What happens during an outbreak?

Measles Outbreaks: What can you do to protect your family?During an identified outbreak of any reportable infectious disease, the health department directs what to do. They attempt to identify and notify all people who are at risk.

Our current outbreak involves several infants from the same unnamed daycare in addition to people not associated with the daycare. I know many families are worried that their child was at that daycare. Families at that daycare will have been notified by the health department already. The health department will track all known contacts of those families.

Local health departments also will notify the public of known locations of potential contact with the virus. The above linked article lists the known locations that infected people visited during their contagious period.

Why are infants at risk?

Infants are at particular risk because they are not typically vaccinated against measles until 1 year of age.

When the virus is in a setting with infants, such as a daycare, it can easily spread.

Infants under 2 years of age who are infected also tend to have more complications from the disease than older children and adults. This is one of the biggest reasons to not wait until 2 years to start immunizations, as some anti-vaccine groups suggest.

If you think you were exposed to or have symptoms of measles

It is IMPERATIVE that you should not leave your house if you suspect you have measles until you have spoken with the health department or your physician.

DO NOT go to a walk in clinic or your doctor’s office unannounced.

You will need to make arrangements to meet someone outside and wear a mask into the building. You will be put in a special negative pressure room, which is not available in most clinics.

Do not go to the pharmacy to pick up medications. Don’t go to the grocery store for food.

Do not leave your home unless it is to a medical facility that knows you’re coming and is prepared.

(Yes, I know I repeated myself for much of this section, but it’s that important!)

The MMR vaccine can help stop the spread

The MMR vaccine is recommended routinely at 12-15 months and again at 4-6 years of age. Vaccines not only help the vaccinated, but provide herd immunity to those too young to be immunized and to those who are immunocompromised.

Please be sure your family is up to date on all their vaccines. All children over 1 year of age should have at least 1 MMR vaccine. All school aged children and adults should have 2 MMRs. By vaccinating your family, you not only protect them, but also those around you!

Why is a second dose given?

The second dose is used to provide immunity to the approximately 5% of people who did not develop immunity with the first dose. It is not a booster because it doesn’t boost the effect of the first dose.

The second MMR helps some people develop immunity if the first vaccine did not work effectively.

This second dose can be given as early as 28 days after the first.

Why don’t we start the vaccine series earlier?

Many parents worry that we don’t give live virus vaccines to infants because they’re less safe, but that’s not why at all.

Maternal antibodies (fighter cells from mom that got into baby during pregnancy) can inhibit the body from being able to build its own antibodies well against a vaccine.

Maternal antibodies are good because as long as they’re in the baby’s body, they fight off germs and protect the infant! They tend to hang around for the first 6-12 months of life.

If a disease has a low incidence, it is acceptable to let the maternal antibodies do their job for the first year.

By the first birthday most maternal antibodies have left the infant, so a vaccine can be used to build the baby’s immunity.

Sometimes we do vaccinate earlier

If there is a high risk of exposure it is recommended to give the vaccine as early as 6 months in case the maternal antibodies are already too low for infant protection.

Many parts of the world have high measles rates so fit into this recommendation. When infants between 6 and 12 months travel internationally, they should receive one dose of MMR vaccine prior to travel.

Sometimes during US outbreaks it is recommended to vaccinate infants 6-12 months. The local health department helps to determine which infants should be immunized in this situation.

If the maternal antibody levels are still high in the infant, the vaccine won’t work. In this situation the baby should still be protected against the disease from mom’s antibodies. That is why this early vaccine does not “count” toward the two needed after the first birthday.

At some point the maternal antibodies go away, we just don’t know when exactly, so the baby who gets the MMR early needs another dose after his first birthday to be sure he’s making his own antibodies once mom’s go away. This dose after the birthday is the first that “counts” toward the two MMRs that are needed.

The next dose of MMR can be anytime at least 28 days after the first counted dose, but we traditionally give it between 4-6 years with the kindergarten shots.

What if someone who hasn’t been vaccinated is exposed?

measles outbreaks, what can you do to protect your family

The MMR vaccine may be effective if given within the first 3 days (72 hours) after exposure to measles. This is why the local health department is so aggressive in identifying cases during an outbreak.

Immune globulin (IGIM, a type of immunity that doesn’t require a person to make their own immunity) may be effective for as long as 6 days after exposure. IGIM should be given to all infants younger than 6-12 months who have been exposed to measles. The MMR vaccine can be given instead of IGIM to infants age 6 through 11 months, if it can be given within 72 hours of exposure.

Are boosters of the MMR needed?

are mmr boosters needed
From my practice Facebook page. Note: In this reply I was going off of my experience many years ago. At that time the advice was only 1 additional MMR, but my research for this blog shows otherwise!

Those of us who work in healthcare must have titers checked to verify immunity to many of the vaccine preventable diseases.

Healthcare workers come into contact with sick patients and patients with weak immune systems, so this is one way to help control disease spread.

From Immunize.org:
Adults with no evidence of immunity (defined as documented receipt of 1 dose [2 doses 4 weeks apart if high risk] of live measles virus-containing vaccine, laboratory evidence of immunity or laboratory confirmation of disease, or birth before 1957) should get 1 dose of MMR unless the adult is in a high-risk group. High-risk people need 2 doses and include healthcare personnel, international travelers, students at post-high school educational institutions, people exposed to measles in an outbreak setting, and those previously vaccinated with killed measles vaccine or with an unknown type of measles vaccine during 1963 through 1967.

Most people don’t know their immune status, and it’s not recommended at this time to check it for the general population.

During an outbreak exposed people might be asked to be tested to help identify risk factors and track disease patterns.

Share Quest for Health

 

It’s not the flu!

I was at the gym today and an otherwise great instructor who seems to know a lot about health was sharing incorrect information about the flu with the class of about 40 people. She said that she had received several texts from other instructors asking her to cover their classes because they were vomiting. Then she went on to say that many at first thought it was food poisoning, but it’s spreading like illness, so it’s the flu, not food poisoning. She made a big deal that the flu is here. Is vomiting from the flu?

She’s only partially right.

Yes…

There’s a stomach bug going around.

It’s not food poisoning.

Influenza is in town.

But this extreme vomiting is not “the flu”

vomiting from the flu
Vomiting can be associated with influenza, but is not the main symptom.

The flu causes predominantly fever, cough, sore throat, and body aches for many days. It can cause vomiting and diarrhea, but those aren’t usually the predominant symptoms. And the flu doesn’t cause just a few hours of extreme vomiting like we’re seeing these days.

Why do I care if people call this stomach bug “flu”?

Runny nose is one of the symptoms of influenza.

The biggest reason I care is that it leads people to make other incorrect assumptions and to get the wrong treatments.

I hear all the time that people had the flu the year they got a flu shot, so they don’t want to get it anymore.

When probed about their illness, it’s usually not consistent with the flu. It was either a cold and cough or a stomach virus.

If they think a common cold or vomiting is from the flu, they’re mistaken.

They need to know that this isn’t the flu.
Cough is one of the most common symptoms of influenza, along with fever, sore throat, and body aches.

Common colds and vomiting are not prevented with the flu shot.

The flu shot has nothing to do with protecting against most cases of vomiting and diarrhea or most upper respiratory tract infections.

Of course there are people who got the flu shot (or FluMist when it was available) who did come down with the flu. They had a positive flu test and symptoms were consistent with the flu. But if they get influenza after the vaccine they tend to have milder symptoms. They tend to not end up in the hospital or dead if they’ve had the vaccine. Yes, even healthy young people can end up very sick from influenza. They can even die. (The FluMist didn’t protect well and was removed from the market due to this.)

We forget about all the times people did get the vaccine and they didn’t catch the flu even with likely exposure. Lack of disease is easy to fail to acknowledge.

We know the flu vaccine is imperfect. But if the majority of people get vaccinated, we can slow the rate of spread and protect us all against influenza most effectively.

We don’t have great treatments for influenza, so vaccinating and using other precautions is important!

HPV Vaccine Concerns

The large majority of the parents who bring their children to my office want their children to be vaccinated against any disease we can protect them against. The HPV vaccine is one exception. While most of my patients are given the Gardasil at their 11 or 12 year check up, some parents still “want to do their research” or “have heard things” so they decline to protect their kids at those visits. Sadly they often return year after year and say that they still haven’t done their research, so their child remains unprotected. Sometimes they’ll say that they will let their child decide at 18 years of age. Sadly, by that age many will have already been infected.

I recently had a parent share HPV Vaccine: Panacea or Pandora’s Box? The Costs and Deceptiveness of the New Technology with me. She had concerns based on the information in this article. The first thing I noted was that it is from 2011. This is outdated, since we have learned so much in the six years since it was published, yet like many anti-vax articles, it continues to circulate online.

 The first argument is that it won’t last long enough.

It is therefore possible that the protective effects of the vaccination will wane at the time when women are most susceptible to the oncogenic effects of the virus (those over 30), providing protection to those who do not need it (adolescents) and failing to provide protection to those who do (women over 30).

Studies show protection lasts 10 years and hasn’t dropped by that time. If future studies show a booster is needed, we can add that. That in no way should mean to not give protection for the years it is really needed – adolescence and young adult life. I cannot agree with the statement that providing protection “to those who do not need it (adolescents)” at all. Yes teens need protection. I’ll get more into their risks below. And the fact that women over 30 are more likely to develop the cancer does not mean that is when they come into contact with the virus. It’s kind of like saying that kids don’t need to brush their teeth because they don’t have cavities. If you wait for the cavities to develop, it’s too late!

The second argument is based on old version of the vaccine.

We now use the 9 valent variety, which covers the large majority of cancer causing strains. Again, even if there are other strains, why not protect against what we have?

Natural immunity lasting longer than vaccine immunity?

The argument that natural immunity will last longer than the vaccine immunity is not a valid argument. Natural immunity can wane with some diseases too, and if we can protect against the disease, it is preferable. Boosters for many vaccines are needed when we know immunity wanes. That’s okay. Some parents advocate to not vaccinate and get the real disease. When their kids get whooping cough they’re miserable. Many are hospitalized. Some even die. I’d rather do boosters! (This may be a bad example because I don’t think our booster for whooping cough lasts long enough and there are complications with giving boosters more often, but ongoing surveillance and research will continue and hopefully improve the situation.)

The cost issue is interesting.

If it was not cost effective in the long run, insurance companies wouldn’t pay for it. It’s that simple. They’ve done the math. Australia is a great example. Their cancer rates are down because HPV is a mandatory vaccine.

Debunking Risks

The risks listed have all been shown to not be as risky as once shown.

Abstinence as prevention?

The article also alludes to this being a sexually transmitted disease so we can just teach abstinence until marriage.

There are so many things wrong with this.

First, this virus can spread through non-intercourse activities, which can be part of a normal and healthy teen relationship.

Second, even if your child is a virgin at marriage, their spouse might not be. Or the spouse could die and they remarry.

Or there could be infidelity in marriage.

There may not be signs of this virus during an infection. Testing for HPV is recommended for women over 30 years of age, but is not available for men at any age, so teens and young adults will not know if they have the virus or not.

And we know that abstinence only teaching fails. Some people raised in strict Christian households have sex outside of marriage.

Teaching kids to protect themselves is much more effective to prevent many sexually transmitted infections, but condoms don’t always protect against HPV transmission.

And there’s always rape. One out of four women has been sexually assaulted. One in four! What a horrible thing to be raped. Then to find out you get cancer from that…

What about males?

They argue it hasn’t been tested in males.

It has.

And it cuts cancer rates in men too. They’re not just vectors as stated in the article.

We keep learning

This article is several years old.

It didn’t yet know that the cancer rates in Australia would fall like we now know.

We’ve learned much more information than they knew in 2011 when it was written.

We know the HPV vaccine is safe.

It is best given before the teen years to induce the best immune response and to get kids protected before the risk of catching the virus becomes more likely.

It isn’t a lifestyle choice to get this virus, as it seems the author claims. People have sex. This virus and other infections can spread through sex. But this virus is also spread without intercourse (such as through oral sex or skin to skin contact without sex), which is why 80% of the adult population has had the virus at some point.

If you don’t think the risk is real

Someone You Love is a documentary that follows several women with HPV related cancer. If you still think the vaccine isn’t worth it for your child, watch it. I am not paid in any way to recommend this. It simply is a powerful documentary that shows the devastation of HPV disease and you should see that before saying your child doesn’t need protection.

Do I recommend the vaccine?

I strongly feel this is a safe and effective vaccine. So much so that my own teens received three doses of the original Gardasil and one dose of Gardasil 9 despite no official recommendations for this booster. I want to protect them in any way that I can.

If I had any concerns about its safety I would not have given it to my own children.

I don’t think I can list any study or give any argument stronger than that.

Many people raise concerns about the HPV vaccine, but the studies show it's safe and effective to prevent cancer in both men and women.
