Why Are We More Careful About Introducing Baby Food Than Giving Vaccines?

The rules about introducing baby food have changed a lot over the years.

Believe it or not, instead of rice cereal, when your baby is ready for solid foods, you can now give her fruits, veggies, meat, or even peanut butter. That’s right, infants can have peanut butter!

In fact, if your baby has eczema, your pediatrician will likely encourage you to introduce peanut butter early, by four to six months, as a way to hopefully avoid peanut allergies later in life.

Why Are We More Careful About Introducing Baby Food Than Giving Vaccines?

Those are some big changes, aren’t they.

Still, a lot of other things stayed the same, including that parents should:

  • wait until at least four months, and often until six months, before they think about starting solid foods
  • only give one new food at a time

So while there are few restrictions on which foods to give now (still no honey before age 12 months and no choke foods), you still want to introduce one new food every three or four days to watch for a reaction.

Why is that different than for vaccines?

It’s because reactions to foods are more common, especially non-allergic type reactions (diarrhea, gas, and fussiness, etc), but also because there is basically no risk to delaying the introduction of new foods by this slow method.

There is also no real benefit to going much faster. Do you really want to introduce your baby to multiple new foods a day?

In addition to allergies and intolerances, there is another type of reaction you are watching for too – your baby simply not liking the food. For example, if one of your baby’s first foods is an apple, strawberry, beet combo puree and he spits it out at the first taste, how are you going to know which flavor he didn’t like? Isn’t it better to go through all of the single ingredient first foods before mixing them up?

Now if you did the same thing with vaccines, your baby would be getting a shot every four days! And it would leave them unprotected for a lot longer period of time.

Considering that serious vaccine reactions are rare, it is easy to understand that there is no benefit to only giving one vaccine at a time and we recommend that folks stick to the standard immunization schedule.

What to Know About Giving Vaccines and Introducing Baby Food

Although it is like comparing peas with peach mango and oatmeal cereal, stick to your pediatricians advice about vaccines and introducing baby food.

What Are the Pro and Con Arguments for Vaccines?

Is it still OK to “debate” vaccines and vaccine safety?

Sure.

pro-con-vaccines
Using fallacious arguments and anti-vaccine propaganda can not be part of any real debate about vaccines.

What’s not up for debate anymore is the idea that vaccines aren’t safe or necessary or that vaccines don’t work.

Folks who use those arguments against vaccines aren’t debating, they are pushing anti-vaccine talking points.

What Are the Pro and Con Arguments for Vaccines?

Why talk about pro and con arguments if we know that vaccines are safe and necessary?

It’s because vaccines aren’t perfect.

 Pro Con
Vaccines save lives. Shots hurt.
Vaccines are cost effective. Vaccines are expensive.
Vaccines work most of the time. Vaccines aren’t 100% effective.
You are much more likely to get shingles after having a natural chickenpox infection. You can get shingles after having the chickenpox vaccines.
Vaccine preventable diseases are much more likely to cause febrile seizures, non-febrile seizures, and worse. Some vaccines cause febrile seizures.
Most vaccine side effects are mild and they prevent life-threatening diseases. Vaccines aren’t 100% safe.
Vaccines can create herd immunity. Some people can’t be vaccinated.
Kids can get protected against at least 16 vaccine-preventable diseases. Kids get at least 13 different vaccines.
Immunity from some vaccine preventable diseases isn’t lifelong either and some diseases, like tetanus, don’t even provide immunity. Immunity from some vaccines isn’t lifelong.
Some vaccine-preventable diseases, like polio, only provide protection against a single serotype, not against all forms of the disease (there are three serotypes of polio). Some vaccines require booster doses.

And sometimes it doesn’t make sense to recommend a vaccine, except in specific circumstances.

“A MenB vaccine series may be administered to adolescents and young adults aged 16–23 years to provide short-term protection against most strains of serogroup B meningococcal disease. The preferred age for MenB vaccination is 16–18 years.”

ACIP on Use of Serogroup B Meningococcal Vaccines in Adolescents and Young Adults: Recommendations of the Advisory Committee on Immunization Practices, 2015

The MenB vaccine, for example, unlike most other vaccines, only has a permissive recommendation – parents may get it for their kids, but they don’t have to.

“First-year college students living in residence halls should receive at least 1 dose of MenACWY before college entry. The preferred timing of the most recent dose is on or after their 16th birthday.”

ACIP on Prevention and Control of Meningococcal Disease: Recommendations of the Advisory Committee on Immunization Practices

In contrast, the recommendation for most other vaccines state that kids “should” receive them.

Why the difference?

Experts aren’t yet sure that the pros of the MenB vaccine, helping avoid MenB disease, outweigh the cons, which include the high cost of the vaccine, short duration of protection, and that it doesn’t cover all MenB subtypes. The cons aren’t about safety.

The Real Vaccine Cons

What about the “cons” you see on some websites about toxins, vaccine-induced diseases, and vaccine deaths?

Beware of folks trying use anti-vaccine talking points to scare or con you when talking about vaccines.
Beware of folks trying use anti-vaccine talking points to scare or con you when talking about vaccines.

This is when it becomes helpful to understand that the word “con” has multiple definitions.

vaccine-conThese sites use anti-vaccine experts and other anti-vaccine websites as sources, present anecdotes as real evidence, and cherry pick quotes when they do use real sources.

They also work hard to:

Worst of all, they talk about informed consent and choice, all of the while taking away many parents’ choice to make an informed decision by confusing them with misinformation, myths, and propaganda.

Of course, parents who have taken the time to get educated about vaccines don’t fall for any of these arguments.

They know that the evidence overwhelmingly shows that vaccines work, vaccines are safe, and vaccines are necessary.

What to Know About the Pro and Con Arguments for Vaccines

In any real debate, getting vaccinated and protected wins every time, because vaccines work and they are safe and necessary.

Abuse of Vaccine Exemptions

Every state has laws mandating vaccines to attend school and daycare.

Every state also allows exemptions to those mandates, including:

The way that  these laws and exemptions are set up leaves a lot of room for abuse though.

Abuse of Religious Exemptions

How many religions are actually against kids getting vaccinated?

That’s right, almost none.

So why are there so many religious vaccine exemptions in most states, especially in states that don’t have a personal belief exemption?

Right again.

Folks who don’t want to vaccinate their kids, and can’t use a personal belief exemption, just say that vaccinating them would be against their religion.

Abuse of Medical Exemptions

There are some children who shouldn’t be vaccinated.

These children can get a true medical exemption to one or more vaccines because they have a real contraindication or precaution to getting vaccinated.

“If a child has a medical exemption to immunization, a physician licensed to practice medicine in New York State must certify that the immunization is detrimental to the child’s health. The medical exemption should specify which immunization is detrimental to the child’s health, provide information as to why the immunization is contraindicated based on current accepted medical practice, and specify the length of time the immunization is medically contraindicated, if known.”

Dear Colleague letter regarding guidelines for use of immunization exemptions

Fortunately, these medical reasons to skip or delay vaccines are not very common and are often temporary. They can include the contraindications and precautions listed in the package insert for each vaccine and by the Advisory Committee on Immunization Practices, with the most common medical exemptions being:

  • a severe allergic reaction to a previous dose
  • a severe allergic reaction to a vaccine component
  • a known severe immunodeficiency and live vaccines
  • a moderate or severe acute illness with or without fever (precaution)
  • a progressive neurologic disorder (precaution)
A family history of these conditions would not be a reason to skip or delay any vaccines.
Although it will get you a medical exemption for just $120 in California, a family history of these conditions would not be a reason to skip or delay any vaccines.

Most other things are “incorrectly perceived as contraindications to vaccination” and should not be a medical exemptions, including having :

  • a mild acute illness with or without fever
  • a mild to moderate local reaction
  • relatives with allergies
  • a family history of seizures
  • a stable neurologic condition
  • an autoimmune disease
  • a family history of an adverse event after DTP or DTaP administration

A medical exemption can also exist if your child already had the disease and so has natural immunity. In most cases, except for chicken pox disease, titers will likely need to be done to prove that your child already has immunity.

Stopping the Abuse of Vaccine Exemptions

We know that vaccine exemptions are being abused.

How do you stop it?

“Permitting personal belief exemptions and easily granting exemptions are associated with higher and increasing nonmedical US exemption rates. State policies granting personal belief exemptions and states that easily grant exemptions are associated with increased pertussis incidence.”

Omer et al on Nonmedical exemptions to school immunization requirements: secular trends and association of state policies with pertussis incidence.

You likely have to make it harder to get a vaccine exemption.

Strong exemption laws, which are needed in many states, make it clear that:

  • many exemptions are temporary
  • medical exemptions are based on ACIP guidelines, current accepted medical practice, and evidence based medicine – not anecdotes
  • religious exemptions specifically exclude philosophical exemptions and must reflect a sincere religious belief
  • exempted students will be excluded from school during outbreaks
  • exemptions should include a signed affidavit that is notarized
  • exemptions should be recertified each year
  • a separate exemption application will be needed for each vaccine

Getting an exemption shouldn’t be easier than getting vaccinated! And it should include some degree of education against the myths and misinformation that scares parents away from vaccinating their kids.

“Because rare medically recognized contraindications for specific individuals to receive specific vaccines exist, legitimate medical exemptions to immunization requirements are important to observe. However, nonmedical exemptions to immunization requirements are problematic because of medical, public health, and ethical reasons and create unnecessary risk to both individual people and communities.”

AAP on Medical Versus Nonmedical Immunization Exemptions for Child Care and School Attendance

You could also get rid of nonmedical vaccine exemptions.

Of course, for that to work, you can’t allow just anything to count as a medical exemption.

“Review of all medical exemption requests will be conducted at the Mississippi State Department of Health by the State Epidemiologist or Deputy State Epidemiologist.”

Mississippi Medical Exemption Policy

In Mississippi, for example, where medical exemptions are reviewed and approved by the State Epidemiologist or Deputy State Epidemiologist, there were just 208 medical exemptions in the whole state during the 2016-17 school year.

In some states, rates of medical exemptions might be six or seven times higher. This is mostly seen in states that don’t allow personal belief exemptions and make it difficult to get a religious exemption.

That seems to be the case in Nebraska, where there are no personal belief exemptions and you have to submit a notarized statement to get a religious exemptions. Their high rates of medical exemptions likely reflect some abuse and the fact that medical exemptions aren’t reviewed or approved by anyone, they just reflect “that, in the health care provider’s opinion, the specified immunization(s) required would be injurious to the health and well – being of the student or any member of the student’s family or household.”

As we are seeing, that simply invites vaccine exemption abuse.

Very few states currently require that exemption applications go to the health department for review. Those that do include Alabama, Arkansas, Michigan, Minnesota, Mississippi, and West Virginia.

California is notably absent. I guess they didn’t see the potential for abuse when they passed their latest vaccine law. I mean, who could have guessed that doctors would actually be selling medical exemptions to parents based on unrelated conditions, like a family history of diabetes, celiac disease, or autism?

The non-medical vaccine exemption form in Colorado includes information on the risks of each vaccine-preventable disease.
The non-medical vaccine exemption form in Colorado includes information on the risks of each vaccine-preventable disease.

At the very least, until we have stronger exemption laws, parents who want to get a nonmedical exemption should acknowledge that they understand the risks they are taking when they skip or delay their child’s vaccines.

What to Know About Abuse of Vaccine Exemptions

While medical exemptions are necessary for kids who have true contraindications to getting vaccinated, stronger laws can help decrease the abuse we see in medical, religious, and personal belief vaccine exemptions.

Rash After the MMR – Is This Normal?

It is not uncommon to get a rash after your child gets their MMR vaccine.

In fact, about 1 in 20 people get a rash after their first dose of MMR.

It typically shows up about 6 to 14 days after the dose.

Fortunately, it doesn’t mean that your child has full-blown measles as some people suspect.

Rash After the MMR

So why do some kids get a rash after their MMR?

It depends on which rash they have.

While there is one classic MMR rash that we think about, there are actually a few other rashes that can occur even more rarely, including:

  • hives – an allergic reaction to the vaccine or one of it’s components
  • petechia and/or purpura – caused by temporary thrombocytopenia (low platelet count) in about one out of every 30,000 to 40,000 doses of vaccine given

And then there is the rash that up to 5% or people get about 7 to 10 days after their dose of MMR – a mild vaccine reaction that goes away on its own without treatment.

Most importantly, the presence of this measles-like rash does not mean that your child has actually gotten measles from the vaccine.

How do we know?

For one thing, the MMR vaccine is made with an attenuated or weakened form of the measles virus, so it can’t actually cause full-blown measles, unless maybe a child has a severe immune system problem.

Also, there is no viremia after vaccination.

“There are no reports of isolation of vaccine virus from blood in normal humans.”

Plotkin’s Vaccines

It is also important to note that “person-to-person transmission of vaccine virus has never been documented.”

And kids who get a rash after their MMR vaccine are not considered to be contagious. At most, you would expect them to shed the weakened vaccine virus, but they don’t.

What’s causing this measles-like rash then?

Like the fever, it is thought to be a delayed immune response to the live, attenuated virus in the vaccine.

When the Rash Really is Measles

Are there any situations in which a child gets a rash after their MMR vaccine and it could really be measles?

Sure.

Your child could have been exposed to wild type measles right around the time they got vaccinated, and then went on to develop regular measles.

While getting a measles vaccine within 72 hours of exposure (post-exposure prophylaxis) can reduce your chance of getting measles, it isn’t a perfect strategy.

Or your child could have been vaccinated and been one of the few people for whom the vaccine failed to work. So their rash, again, would be from a wild type strain of measles that they were exposed to and not from the shot.

Can you tell the difference if someone has measles from the vaccine or from a wild type strain?

Sure.

“During outbreaks, measles vaccine is administered to help control the outbreak, and in these situations, vaccine reactions may be mistakenly classified as measles cases.”

CDC on Genetic Analysis of Measles Viruses

You just have to test the measles strain to see if it is the wild type virus or a vaccine strain.

Does It Matter If It Is the MMR Vaccine or Measles?

About now, you are probably wondering why it matters knowing if a child’s rash is caused by measles or the MMR vaccine, right?

For one thing, if a parent thinks a vaccine gave their child measles, then they might not want to get vaccinated again. They will especially think twice about getting another MMR.

Also, if a child really does have full-blown, wild type measles and you simply blame their MMR vaccine, then you might miss someone else in the community that exposed the child to measles. And that’s why some outbreaks are hard to stop.

Lastly, if you simply blame the vaccine, you might miss something else that is causing the child to be sick.

Need an example?

During the 2010 measles outbreaks in Canada, a 15-month-old develop a rash, fever, and other symptoms 12 days after getting their MMR vaccine. Did the have measles, a vaccine reaction, or something else?

Turns out that he had scarlet fever.

The child tested positive for Streptococcus pyogenes (group A streptococcus), the bacteria that causes strep throat and scarlet fever. He also tested positive for vaccine strain measles. He did not have the wild strain of measles, and in fact, did not have measles at all.

Again, he had scarlet fever and it was just a coincidence that he had recently received an MMR vaccine.

But isn’t there another case report from Canada that does prove that you can get full-blown measles from the MMR vaccine? While there is such a case report, it is hardly proof of anything.

“It is possible that the case’s symptoms were not measles-vaccine-related but an inter-current illness confounding the presentation.”

Murti et al on Case of vaccine-associated measles five weeks post-immunisation, British Columbia, Canada, October 2013

The problem with the case?

For one thing, the child already had high levels of IgG antibodies at the time he had the rash, which developed 37 days after he got his vaccine.

“The two-fold rise between acute and convalescent measles-specific IgG suggests the vaccine-mediated immune response had been underway prior to the onset of symptoms.”

Murti et al on Case of vaccine-associated measles five weeks post-immunisation, British Columbia, Canada, October 2013

This was neither a typical reaction nor a typical case. And it very well might not have been measles. If it was, it was a very rare exception to the rule that rashes after the MMR vaccine aren’t full-blown measles.

What to Know About Rashes After the MMR Vaccine

The rash that your child can get after their MMR vaccine is not a sign that they have developed full-blown measles, instead, it is a mild vaccine reaction that will quickly go away without any treatment.

Precautions vs Contraindications When Vaccinating Your Kids

Believe it or not, there are some anti-vaccine folks who believe that all vaccines are dangerous and unnecessary. And they believe that pediatricians push vaccines on kids in all situations, using a one-size-fits-all kind of immunization schedule.

Of course, neither is true.

Vaccines are safe and necessary.

There are some true medical contraindications and precautions to getting vaccinated though. Still, it is important to remember that even more things are simply “conditions incorrectly perceived as contraindications to vaccination.”

Contraindications To Vaccinating Your Kids

There are actually some good reasons to delay or skip one or a few of your child’s vaccines, but only in some very specific situations.

These very specific situations are called contraindications and are what count as medical exemptions.

“A vaccine should not be administered when a contraindication is present; for example, MMR vaccine should not be administered to severely immunocompromised persons.”

CDC on Vaccine Contraindications and Precautions

Fortunately, there are not that many of these contraindications, they are usually specific to just one or a few vaccines, and they are usually, but not always, temporary.

That’s why it would be really unusual to get a true permanent medical exemption for all vaccines. Even if you had a severe allergy to a vaccine that contained yeast, latex, or gelatin, since vaccines contain different ingredients, you would very likely be able to safely get the others.

Remember, your doctor can’t, or at least shouldn’t, just make up contraindications and exemptions to help you avoid getting your kids vaccinated and help you keep them in school.

“I do not believe vaccines had anything to do with my child’s autism. I never noticed any change in his speech, behavior or development with vaccines. I believe the protection and benefits of vaccines far outweigh the risks!”

Michele Han, MD, FAAP

Autism, for example, has been shown to not be associated with vaccines, so it is not a contraindication to getting vaccinated. That’s why many parents vaccinate and protect their autistic kids!

Precautions To Vaccinating Your Kids

In addition to contraindications to getting vaccinated, there is an accompanying list of  precautions.

“A precaution is a condition in a recipient that might increase the risk for a serious adverse reaction, might cause diagnostic confusion, or might compromise the ability of the vaccine to produce immunity (e.g., administering measles vaccine to a person with passive immunity to measles from a blood transfusion administered up to 7 months prior). A person might experience a more severe reaction to the vaccine than would have otherwise been expected; however, the risk for this happening is less than the risk expected with a contraindication. In general, vaccinations should be deferred when a precaution is present. However, a vaccination might be indicated in the presence of a precaution if the benefit of protection from the vaccine outweighs the risk for an adverse reaction.”

CDC on Vaccine Contraindications and Precautions

Again, we are fortunate that most of the conditions that are listed as precautions are temporary.

The vaccine information sheet that you get with each vaccine will list contraindications and precautions on who should not get the vaccine.
The vaccine information sheet that you get with each vaccine will list contraindications and precautions on who should not get the vaccine.

In fact, the most common is having a “moderate or severe acute illness with or without fever.”

Don’t want to get your child vaccinated when he or she has a severe illness?

Don’t worry.

Your pediatrician usually doesn’t want to vaccinate your child in that situation either.

It is easy enough to wait a few days or a week to get vaccinated, when the illness has passed, keeping in mind that a “mild acute illness with or without fever” is neither a precaution nor a contraindication to getting vaccinated. So you can still get your child their recommended vaccines if they just have a cold, stomach bug, or ear infection, etc.

What to Know About Precautions and Contraindications to Vaccines

Although there are some true medical exemptions or contraindications and precautions to getting vaccinated, most are vaccine specific and many are temporary, so they shouldn’t keep you from getting your child at least mostly vaccinated and protected.

More on Precautions and Contraindications to Vaccines

Vaccine Reactions – Is This Normal?

Vaccines are very safe.

They are not 100% safe though and they can have some side effects.

“Considering that the vaccines in the infant schedule are administered to millions of children each year, the list of known adverse events, even rare ones, is impressively short.”

O’Leary et al on Adverse Events Following Immunization: Will It Happen Again?

Fortunately, most of these side effects are harmless and don’t have any long term risks. And of course, the great benefits of vaccines outweigh those risks.

Common Vaccine Reactions

Although most kids don’t have any reactions at all, some do have mild reactions.

Among the possible vaccine reactions or side effects that can occur include:

  • fussiness
  • headache
  • fever
  • body aches
  • redness or swelling at the injection site
  • soreness or tenderness at the injection site
  • tiredness
  • poor appetite
  • chills and sore joints
  • rash
  • diarrhea
  • vomiting
  • swelling of glands in the cheeks or neck

How commonly do they occur?

In this 2011 report, the IOM concluded that few health problems are caused by or clearly associated with vaccines.
In this 2011 report, the IOM concluded that “few health problems are caused by or clearly associated with vaccines.”

These side effects depend on the vaccine that was received and can range from 1 in 3 kids for some fussiness all the way down to 1 in 75 kids for kids who have swelling of their glands.

And they usually begin 1 to 3 days after the vaccine was given and last for 1 to 7 days.  Fortunately, fever and fussiness don’t last that long, typically going away after just a day or two.

Keep in mind that some reactions are more delayed though. This is especially true for the MMR vaccine, in which mild reactions, like a fever, rash, or swelling of glands might not occur until 6 to 14 days after a child got his vaccine.

What can you do if your child has a mild vaccine reaction?

Consult your health care provider, but keep in mind that treatment is often symptomatic, typically with a cold pack or cool cloth/compress for local reactions and pain reliever.

Fainting also commonly occurs after vaccines, especially in teens, but it is thought to be due to the vaccination process itself and not the vaccines. Still, it is something to be aware of.

What About More Moderate Reactions?

More moderate reactions after vaccines are fortunately more uncommon.

“There is low public tolerance of vaccine adverse reactions. Vaccines are therefore only licensed when the frequency of severe reactions is very rare and when only minor, self-limiting reactions are reported.”

WHO on Adverse events following immunization

Some of these moderate reactions might include:

  • febrile seizures
  • high fever
  • persistent crying for 3 or more hours
  • swelling of the entire arm or leg where the shot was given (especially after the 4th or 5th dose of DTaP)
  • a temporary low platelet count (immune thrombocytopenic purpura or ITP)

Like the more common, mild reactions, these less common moderate reactions are also temporary and don’t usually have any lasting risks or consequences.

Then there are the more severe reactions, which thankfully are even more rare. These are the 1 in a million dose type reactions, such as life-threatening allergic reactions.

Of course, you should seek medical attention if you think that your child is having a more moderate or severe reaction to a vaccine.

And lastly, there are the so-called vaccine induced diseases, which are simply made up.

All of these reactions, as well as the risks of getting a natural infection, are listed in each vaccine’s VIS. The Vaccine Information Statements also includes information on how to report all possible vaccine side effects to VAERS.

What to Know About Common Vaccine Reactions

While most kids don’t have any reactions at all after their vaccines, those that do typically have mild reactions, including some fever, soreness, or swelling at the injection site. More moderate and severe reactions are rare.

DTaP Vaccine Reactions – Is This Normal?

Vaccines are very safe.

They are not 100% safe though and they can have some side effects.

Fortunately, most of these side effects are harmless and don’t have any long term risks. And of course, the great benefits of vaccines outweigh those risks.

Common DTaP Vaccine Reactions

Although 75% of kids don’t have any reactions at all, some do have mild reactions.

Among the vaccine reactions or side effects that can occur most commonly include:

Vaccine Information Statements from the CDC highlight the risks of each vaccine.
The DTaP Vaccine Information Statement from the CDC highlight all of the vaccine’s possible risks.
  • fussiness
  • fever
  • redness or swelling at the injection site
  • soreness or tenderness at the injection site
  • tiredness
  • poor appetite
  • vomiting

How commonly do they occur?

They range from 1 in 3 kids for some fussiness all the way down to 1 in 50 kids for vomiting.

And they begin 1 to 3 days after the vaccine was given and last for 1 to 7 days.  Fortunately, fever and fussiness don’t last that long, typically going away after just a day or two.

Treatment is symptomatic, with a cold pack or cool cloth/compress and pain reliever

What About More Extensive Swelling and Redness?

Sometimes the swelling and redness after a DTaP vaccine can be more than you expect though. It might even make you think your child has developed a skin infection.

“Sometimes the 4th or 5th dose of DTaP vaccine is followed by swelling of the entire arm or leg in which the shot was given, lasting 1–7 days (up to about 1 child in 30).”

DTaP Vaccine Vaccine Information Statement

This more extensive local reaction, while scary looking, is not dangerous, and will also go away without long term effects.

It is also not an allergic reaction, so your child can finish the DTaP series if he or she still needs another dose.

Call your pediatrician or seek medical attention if you think your child has developed a skin infection after a vaccination, but keep in mind that bacterial cellulitis after getting a vaccine is an extremely rare, almost unheard of, complication.

Other more moderate and severe DTaP vaccine reactions are uncommon or rare.

“A hypotonic-hyporesponsive episode (HHE) is the sudden onset of hypotonia, hyporesponsiveness, and pallor or cyanosis that occurs within 48 hours after childhood immunizations.”

DuVernoy et al on Hypotonic-hyporesponsive episodes reported to the Vaccine Adverse Event Reporting System (VAERS), 1996-1998

What about hypotonic-hyporesponsive episodes (HHE) and seizures? These were removed as table injuries after DTP back in 1995. It is not that HHE can’t occur after DTP, DTaP, or other vaccines, but rather that HHE doesn’t then cause any permanent neurological damage to the child.

And remember that some so-called vaccine induced diseases are simply made up.

Most of these reactions, as well as the risks of getting natural diphtheria, tetanus, and pertussis infections, are listed in the DTaP VIS.

What to Know About Common DTaP Vaccine Reactions

While most kids don’t have any reactions at all after their DTaP vaccines, those that do typically have mild reactions, including some fever, soreness, or swelling at the injection site.
