Vaccine Injuries vs Coincidences

Believe it or not, some folks don’t think that coincidences are real.

Not believing in coincidences is a well known trope of the anti-vaccine movement.
Not believing in coincidences is a well known trope of the anti-vaccine movement.

Is it a coincidence that these folks are the ones who are the most likely to believe that vaccines cause a lot of injuries and vaccine induced diseases?

Vaccine Injuries vs Coincidences

Thinking about vaccine side effects and coincidences is not new.

“When I undertook the study with the current vaccine strain on my own two triple-negative children and their three playmates, also triple- negatives, I thought: “I am going to do this very carefully now,” and, like Dr. Gear, I set up certain time schedules. I said: “I am going to start to give the vaccine now.” Every time I said “I am going to start to give it” and did not give it, two to three or four days later they came down with either pharyngitis, vomiting and abdominal pain, or a little fever.

I waited for approximately six weeks for those children to stop having some sort of febrile episode. I finally gave up. It so happened that after they got the vaccine they did not have any such episode.”

Albert Sabin on Recent Studies And Field Tests With A Live Attenuated Poliovirus Vaccine

When Albert Sabin was first researching his oral polio vaccine, he understood the problem. How could he really know if any signs or symptoms that occurred after he gave someone his vaccine were really caused by the vaccine, or just a coincidence?

“However, a report later to be given by Dr. Smorodintsev will deal with approximately 7,500 children who had received the vaccine and were carefully followed, as compared with another group, in similar number, who had not, for various types of illnesses which were occurring during the period.”

Albert Sabin on Recent Studies And Field Tests With A Live Attenuated Poliovirus Vaccine

The solution? They studied kids who had not gotten his vaccine.

But you don’t need an unvaccinated group to uncover coincidences.

You can just look at the background rate of a symptom or condition, and compare the periods before and after you start using a vaccine.

For instance, consider this study from Australia about using the HPV vaccine in boys, in which they made some predictions of what would happen after introducing the HPV vaccine.

Assuming an 80% vaccination rate with three doses per person — which equates to about 480 000 boys vaccinated and a total of 1 440 000 doses administered nationally per year in the first 2 years of the program — about 2.4 episodes of Guillain-Barré syndrome would be expected to occur within 6 weeks of vaccination. In addition, about 3.9 seizures and 6.5 acute allergy presentations would be expected to occur within 1 day of vaccination, including 0.3 episodes of anaphylaxis.

Clothier et al. on Human papillomavirus vaccine in boys: background rates of potential adverse events.

Wait. Are they saying that the HPV vaccine is going to cause Guillain-Barré syndrome, seizures, allergic reactions, and anaplylaxis?

Of course not. When the study was done, the kids hadn’t gotten any vaccines yet!

That was the background rate of those conditions.

They happened before the vaccine was given, and you can expect them to continue to happen after these kids start getting vaccinated – at that same rate.

What if they start happening more often after kids get vaccinated?

Then it makes it less likely to be a coincidence and more likely that the vaccine is actually causing an increase in the background rate. And vaccine safety studies look for that, which is how we know that vaccines don’t cause SIDS, transverse myelitis, multiple sclerosis, and many other conditions.

Most of you will have heard the maxim “correlation does not imply causation.” Just because two variables have a statistical relationship with each other does not mean that one is responsible for the other. For instance, ice cream sales and forest fires are correlated because both occur more often in the summer heat. But there is no causation; you don’t light a patch of the Montana brush on fire when you buy a pint of Haagan-Dazs.

Nate Silver on The Signal and the Noise

Of course, when we are talking about coincidences, we are also talking about correlation and causation.

When correlation doesn’t equal causation, then it’s probably a coincidence. Or it’s at least caused by some other factor.

And coincidences happen all of the time.

Is It a Vaccine Injury or a Coincidence?

That something could be a coincidence is not typically want parents want to hear though, especially if their child has gotten sick.

What does it mean that something happens coincidentally?

“Most sudden cardiac deaths that remain unexplained after necropsy are probably caused by primary cardiac arrhythmias.”

Sudden death in children and adolescents

Often it just means that it is unexplained. And that it is chance alone that it occurred as the same time as something else.

“In the absence of a specific etiology for ASDs, and a tendency among parents of children with a disability to feel a strong sense of guilt, it is not surprising that parents attempt to form their own explanations for the disorder in order to cope with the diagnosis.”

Mercer et al on Parental perspectives on the causes of an autism spectrum disorder in their children

Again, when folks blame vaccines, it is often because they have nothing else to blame.

“In some fraction of the American population, however, the belief in a link remains. One reason is a coincidence of timing: children are routinely vaccinated just as parents begin to observe signs of autism. Most vaccines are administered during the first years of life, which is also a period of rapid developmental changes. Many developmental conditions, including autism, don’t become apparent until a child misses a milestone or loses an early skill, a change that in some cases can’t help but be coincident with a recent vaccination.”

Emily Willingham on The Autism-Vaccine Myth

Think that it is too big of a coincidence that some infants develop spasms shortly after their four month vaccines?

Dr. William James West first described these types of infantile spasms in the 1840s!

And the “Fifth Day Fits,” seizures that began when a newborn was five days old, was described in the 1970s, well before we began giving newborns the hepatitis B vaccine.

But SIDS was only discovered after we began vaccinating kids, right?

“But, with millions upon millions of doses given each year to infants in the first 6 months of life across industrialized countries and with sudden infant death syndrome being the most common cause of infant death among infants 1 month or older, the coincidence of SIDS following DTP vaccination just by chance will be relatively frequent. When the two events occur, with SIDS following vaccination, well-meaning and intelligent people will blame the vaccine. They seek order out of randomly occurring events.”

Jacobson et al. on A taxonomy of reasoning flaws in the anti-vaccine movement

Of course not.

Cases of SIDS have been described throughout recorded history and have been well studied to prove that they are not associated with vaccines.

“Some events after immunisation are clearly caused by the vaccine (for example, a sore arm at the injection site). However, others may happen by coincidence around the time of vaccination. It can therefore be difficult to separate those which are clearly caused by a vaccine and those that were going to happen anyway… Scientific method is then used to determine if these events are a coincidence or a result of the vaccine.

Vaccine side effects and adverse reactions

It is easy to blame a vaccine when something happens and a child was recently vaccinated. That is especially true now that anti-vaccine folks turn every story of a child’s death or disability into a vaccine injury story.

“Autism was known well before MMR vaccine became available.”

Chen et al. on Vaccine adverse events: causal or coincidental?

Blaming vaccines when it is clear that vaccines aren’t the cause doesn’t help anyone though. It scares other parents away from vaccinating and protecting their kids. And it doesn’t help parents who need support caring for a sick child or help coping with the loss of a child.

What to Know About Vaccine Injuries vs Coincidences

While all possible adverse events after getting a vaccine should be reported to VAERS and your pediatrician, remember that just because something happened after getting vaccinated, it doesn’t mean that it was caused by the vaccine.

Personal Stories About Vaccine-Preventable Diseases

Parents these days seem to get bombarded with vaccine injury stories and videos on Facebook.

Is that because vaccines cause so many bad reactions?

Of course not.

It’s because some folks think that everything that happens to their kids is a vaccine injury.

Personal Stories About Vaccine-Preventable Diseases

If you are going to watch those videos and listen to their stories, getting scared in the process, be sure to also listen to the stories of parents who’s kids have suffered through actually getting a vaccine-preventable disease.

While it’s great that these diseases are much less common because most people vaccinate and protect their kids, one side effect of that progress is that we don’t have many reminders of just how terrible these diseases are anymore.Have you ever seen a baby with congenital rubella syndrome?

Or a child with tetanus or diphtheria?

Have you ever even seen photos of these diseases?

Will you read these stories of parents who have lost a child to a vaccine-preventable disease.

“Kimberly Coffey was buried three days before her high school graduation in the prom dress she didn’t get to wear. She didn’t have the opportunity to be vaccinated against Meningitis B.”

Kim’s Meningitis Story

In Kimberly‘s case, the Men B vaccine wasn’t yet available, but in many other cases, parents have shared their stories of unvaccinated children who suffered with a disease that was vaccine preventable at the time.

“From 2010 to 2016, young children continued to be at the greatest risk for influenza-associated pediatric deaths. Children without preexisting medical conditions accounted for half of all deaths. Vaccination coverage was low among influenza-associated pediatric deaths.”

Shang et al. on Influenza-Associated Pediatric Deaths in the United States, 2010–2016

Tragically, there are also many flu stories.

But the flu isn’t the only vaccine-preventable disease that still harms children.

This family didn't have a choice about their son getting sick - he was too young to be vaccinated when he was exposed to an unvaccinated child with measles.
This family didn’t have a choice about their son getting sick – he was too young to be vaccinated when he was exposed to an unvaccinated child with measles

There are other diseases. Other stories.

Read these stories.

Listen to these parents.

Are the stories supposed to scare you into vaccinating your kids?

Of course not. Just like you shouldn’t let the myths and propaganda from the anti-vaccinate movement scare you away from vaccinating and protecting your kids.

Instead of being motivated by fear, you should make your decision because you understand that the many benefits of vaccines are far greater than their small risks.

What to Know About Vaccine-Preventable Disease Stories

Reading stories of vaccine-preventable diseases are a good reminder that these diseases are not so mild as some folks suggest, and they are instead life-threatening diseases that are best avoided by getting fully vaccinated.

Learn the Risks of Falling for Anti-Vaccine Propaganda

If you are on the fence or hesitant to vaccinate your kids, it might not be easy to recognize that the vaccine information that you get on some sites is pure propaganda.

That’s unfortunate, because you can’t make an informed choice about vaccines if you are basing that decision on misinformation.

Learn the Risks of Falling for Anti-Vaccine Propaganda

Take the infographic about the number of vaccine doses children in the United States normally get.Learn the risks of following bad advice about vaccines.

It is designed into making you think that kids get 72 doses of vaccines, scaring you and trying to reinforce the myth that kids get too many vaccines.

Have you seen and fallen for that trick? Did you ever think to actually count the total vaccine doses they list? As you can see above, it doesn’t come out to 72 doses

But why do  they do it? If they really think their “vaccines contain toxic chemicals” argument is convincing, then would it matter if the number of vaccine doses was 11 or 53 or 72? Why inflate it to make it wound scarier?

Still, however you want to count the number of doses of vaccines kids get today, one thing is crystal clear –  they get protection from more vaccine-preventable diseases.

In 1983, kids may have only have gotten 11 doses of vaccines, but many still died from Hib pneumonia and meningitis, epiglotitis (Hib), pneumococcal pneumonia and meningitis, hepatitis A, hepatitis B, rotavirus, chicken pox, and meningococcemia, etc.

“for those trained in pediatrics in the 1970s, Hib (Haemophilus influenzae type b) was a horror.”

Walter Orenstein, MD

Today, unless you decide to skip or delay your child’s vaccines, they are protected from these diseases.

What about the flu? Kids still die with the flu, but it is important to keep in mind that most kids who die with the flu are unvaccinated.

That’s why it is important to get your kids vaccinated. Don’t take the risk of following bad advice.

Can Vaccines Cause Kawasaki Disease?

Kawasaki disease is rare and there is a good chance that you have never even heard of it, even though the first case was diagnosed in 1961.

Kids with this condition are typically irritable and can develop high fever, swollen glands in their neck, red eyes, red, cracked lips, red, swollen hands and feet, and a rash.

If you have heard of it, there is a good chance it is because anti-vaccine folks are using Kawasaki disease to scare you away from vaccinating and protecting your kids. Lately, talk about Kawasaki disease and the meningococcal B vaccines have been going around.

What Causes Kawasaki Disease?

Kawasaki disease is a type of vasculitis.

Kids who develop Kawasaki disease, who are typically under age 5 years, develop inflammation of their blood vessels, which leads to many of the symptoms and complications we see.

What causes this inflammation?

“Evidence suggests that Kawasaki disease may be linked to a yet-to-be identified infectious agent, such as a virus or bacteria. However, despite intense research, no bacteria, virus, or toxin has been identified as a cause of the disease.”

AAP on Kawasaki disease

We don’t know.

Can Vaccines Cause Kawasaki Disease?

Ask about Kawasaki disease if your child has a fever for five days and other symptoms of Kawasaki disease.
Courtesy of the kdfoundation.org

Because the cause of Kawasaki disease is unknown, that leads some folks to think that it could be vaccines.

Could it?

That vaccine clinical trial data sometimes finds a higher, although not statistically significant risk for Kawasaki disease, gets some of those folks thinking about it even more, except they don’t seem to think about the fact that the risk is never statistically significant.

But aren’t there case reports of kids getting Kawasaki disease after getting a hepatitis A, yellow fever, hepatitis B, or flu vaccine?

Yes, but getting a case report published about one patient who you think got Kawasaki disease soon after getting a vaccine isn’t strong evidence that it wasn’t a coincidence.

“Childhood vaccinations’ studied did not increase the risk of Kawasaki disease; conversely, vaccination was associated with a transient decrease in Kawasaki disease incidence. Verifying and understanding this potential protective effect could yield clues to the underlying etiology of Kawasaki disease.”

Abrams et al. on Childhood vaccines and Kawasaki disease, Vaccine Safety Datalink, 1996-2006.

And not surprisingly, several studies have shown that there isn’t any extra risk for Kawasaki disease after routine vaccines.

One even showed that getting vaccinated could be protective! Another benefit of vaccines and another reason you shouldn’t skip or delay your child’s immunizations.

What to Know About Vaccines and Kawasaki Disease

While anti-vaccine folks often list Kawasaki disease among their vaccine-induced diseases, several studies have shown that vaccines are not associated with Kawasaki disease, except to maybe have a protective effective if you are fully vaccinated.

Dear Anti-Vaxxers,

As someone who has always understood that vaccines are safe and necessary, who vaccinates his children, I’m asking you to hear me out.

Dear anti-vaxxers. Vaccinate your kids.

I don’t think that you are either stupid, uneducated, crazy, or that questioning vaccine safety is always associated with  believing in conspiracy theories.

I understand and appreciate that you do care about your children, that you care about their health, and that you want what’s best for your family.

I actually do get that. I really do.

But I know that while you believe that you have done years of research and investigation to help you decide that the potential benefits of vaccines don’t outweigh their risks, going out of your way to find information to support your decision and ignoring all of the rest that says you are wrong, isn’t really doing research.

Whether you have never set foot on a college campus, you have a PhD in immunology, or you are a toxicologist, I know that you are still vulnerable to the same cognitive biases, heuristics, and logical fallacies as everyone else, and those can keep you from coming to a truly informed decision.

And I know that you are mostly motivated by fear, anger, and mistaken ideas of vaccine injury, vaccine induced disease, and unexplained illness and sudden deaths.

We all care about our children and families. The difference between us is that you still believe that there are two sides to the vaccination debate.

There isn’t.

Vaccines are safe, necessary, and they work well to protect our kids from life-threatening vaccine-preventable diseases.

No, vaccines are not 100% safe and they don’t work 100% of the time, but neither are they responsible for all of the things you see in vaccine scare stories or all of the so-called vaccine induced diseases we hear about.

“What if doctors never actually learn about vaccines, their ingredients, or adverse events, in medical school? What if the medical textbooks are written with an enormous amount of funding from the pharmaceutical industry? What if the CDC owns patents on vaccines? What if the pharmaceutical industry is corrupt and funds studies which conveniently stop monitoring test subjects before adverse effects begin to manifest? What if vaccines contain toxic substances at levels which can cause chronic illness when children are repeatedly injected with them? What if we are trading temporary illness for the development of autoimmune and neurological disease later in life? What if the threat and danger of these “preventable” diseases has been inflated to push more vaccines? What if these vaccines are not even truly effective as we have been led to believe and we will always need more booster shots to try to make up for that fact? What if there is evidence for all of the above, you just haven’t seen it yet?”

Ashley Everly Cates

Listen.

If you don’t want to vaccinate your kids, then don’t.

But don’t be influenced by folks who say they have done their research and don’t believe in conspiracy theories, but use a book by Neil Z Miller as a reference and push every major anti-vaccine conspiracy theory.

And don’t expect that your vaccine choice will be consequence free, including that your child will be at increased risk to get a vaccine-preventable disease, you will be putting others at risk to get a vaccine-preventable disease if your intentionally unvaccinated child gets sick, and you may be kept out of daycare or school if you live in a state that doesn’t allow non-medical exemptions.

I hope that you will keep an open mind and genuinely take time to look into this for yourself, beyond the myths and claims of anti-vaccine heroes who ignore or are unaware of the massive amount of evidence that contradict their claims.

Please take caution and know that I don’t do this to be popular. I don’t do this to make friends, get likes on my Facebook page, or sell vitamins and supplements in an online store.

Truly. The only reason I speak out is to protect my children and your children from unnecessary harm.

After all, is it really so hard to believe that the great majority of pediatricians, infectious disease specialists, immunologists, toxicologists, and public health experts in the world and throughout history are right about vaccines?

But If It Wasn’t the Vaccines…

Do you know why some folks still think vaccines are associated with autism?

It is simply because we can’t tell them what does cause autism.

“In the absence of a specific etiology for ASDs, and a tendency among parents of children with a disability to feel a strong sense of guilt, it is not surprising that parents attempt to form their own explanations for the disorder in order to cope with the diagnosis.”

Mercer et al on Parental perspectives on the causes of an autism spectrum disorder in their children

So if we don’t have another answer – then it must be vaccines.

That helps explain a lot of vaccine injury stories too.

For example, doctors often can’t tell you why your child has allergies, asthma, Celiac disease, diabetes, eczema, multiple sclerosis, POTS, SIDS, or thyroid problems, etc., which makes some people look to the mistaken theory that they were triggered by vaccines.

Of course, the answer isn’t that these are vaccine-induced diseases.

It simply demonstrates the limits of medical technology. Even if we don’t know what does cause many of these diseases, in almost all cases, it has been shown that they are not associated with vaccines.

Limits of 21st Century Medical Technology

Even in the 21st Century, science and medicine don’t have all of the answers.

And sometimes the answers are there, but are misinterpreted.

For example, the National Association of Medical Examiners makes the following distinctions on a medical certificate between manner of death:

  • Natural — “due solely or nearly totally to disease and/or the aging process.”
  • Accident — “there is little or no evidence that the injury or poisoning occurred with intent to harm or cause death. In essence, the fatal outcome was unintentional.”
  • Suicide — “results from an injury or poisoning as a result of an intentional, self-inflicted act committed to do self-harm or cause the death of one’s self.”
  • Homicide — “occurs when death results from…an injury or poisoning or from… a volitional act committed by another person to cause fear, harm, or death. Intent to cause death is a common element but is not required for classification as homicide.”
  • Could not be determined — “used when the information pointing to one manner of death is no more compelling than one or more other competing manners of death when all available information is considered.”
  • Pending investigation — “used when determination of manner depends on further information”

Why is this important to know?

Because many people confuse a natural cause of death as meaning that there was nothing wrong. That’s actually the opposite of what it means! A natural cause of death in a child means that they died because of a disease or condition.

Which disease or condition?

What was the underlying or immediate cause of death in these cases?

Limits and Uncertainty in Medicine

That’s where the limits of modern medicine and modern medical technology come in…

Maybe technology will change the future of healthcare – hopefully for the better, but there are still many things it can’t do.

Sure, we have indexed or mapped the entire human genome, but we still can’t often tell you why your child has a cough or runny nose, has developmental delays, or didn’t make it out of the PICU.

“…finding an underlying diagnosis for many conditions can be a very long and frustrating experience. A diagnosis can take as many as five years, and occasionally may never happen, especially with rare conditions. In addition, some experts say that between 30 to 40 percent of children with special needs do not have an exact diagnosis.”

NIH on Learning About An Undiagnosed Condition in a Child

Everyone wants answers when a child is sick or has unexplained signs and symptoms, especially when a child dies.

Unfortunately, while it may not get talked about often enough, there are many limits to modern medicine. There is often some uncertainty too.

“…when parents perceive greater uncertainty, they perceive less control over their child’s condition.”

Madeo et al on Factors Associated with Perceived Uncertainty among Parents of Children with Undiagnosed Medical Conditions

Just because futuristic medical tools like Tricorders are on the way doesn't mean that we will have all of the answers.
Just because futuristic medical tools like Tricorders are on the way doesn’t mean that we will have all of the answers.

Doctors don’t know everything.

The best doctors are the ones that actually know that they don’t know everything.

But just because they don’t know everything, that doesn’t mean that they don’t know anything.

For example, not knowing what does cause autism doesn’t mean that we don’t know many of the things that aren’t linked to autism.

And it certainly doesn’t mean that you should use this an excuse to blame vaccines or to skip or delay any vaccines. Continuing to try and associate vaccines with autism doesn’t just frighten parents and leave kids unprotected, it hurts autistic families.

What to Know About Uncertainty in Medicine

While there is much uncertainty in modern medicine and doctors don’t have all of the answers, there is no evidence that vaccines are associated with autism.

What Are the Risks of Vaccines?

Vaccines are very safe, but they are not 100% risk free.

They are certainly not as high risk as some anti-vaccine folks will have you believe though.

“Vaccine hesitation is associated with perceived risk. Since vaccine-preventable diseases are rare, an adverse event from a vaccine is perceived by the parent to be of greater risk. Risk perception is critical.”

AAP on Addressing Common Concerns of Vaccine-Hesitant Parents

And when you consider their great benefits, it is easy to see why the great majority of parents get their kids fully vaccinated and protected against all recommended vaccine-preventable diseases.

Risk Perception and Vaccine Hesitancy

Even though the risks and side effects of vaccines are very low, some people think that they are much higher. This is often amplified because of vaccine scare stories and the misinformation found on anti-vaccine websites.

“No intervention is absolutely risk free. Even the journey to a physician’s office with the intention to receive a vaccination carries the risk of getting injured in an accident. With regards to risks of vaccination per se, one has to distinguish between real and perceived or alleged risks.”

Heininger on A risk–benefit analysis of vaccination

Other problems with risk perception include that some people:

  • can be more likely to avoid risks that are associated with an action or having to do something vs. those that involve doing nothing or avoiding an action, even if inaction (skipping or delaying a vaccine) is actually riskier
  • often think about risks based on their own personal experiences (you remember someone’s vaccine injury story), rather than on scientific evidence

These biases in the way we think about risk can actually lead us to make risky choices and they help explain why some people are still so afraid of vaccines. Parents might think the risk of a possible side effect, some of which don’t even exist, is worse than the risk of getting a vaccine-preventable disease, getting someone else sick, or starting an outbreak. Parents also often underestimate the risk of their decision to not vaccinate their child.

“As much previous research claims, this study confirms that individuals characterized by greater trust of healthcare professionals and the possession of more vaccine-related knowledge perceive higher levels of benefits and lower levels of risks from vaccinations.”

Song on Understanding Public Perceptions of Benefits and Risks of Childhood Vaccinations in the United States

So what’s the answer? It is likely for folks to get better educated about vaccines, including getting a good understanding of both their benefits and risks.

What Are the Risks of Vaccines?

Again, vaccines are not 100% safe or risk free.

Most vaccines have some common, mild side effects, which might include (depending on the vaccine):

Vaccine Information Statements from the CDC highlight the risks of each vaccine.
Vaccine Information Statements from the CDC highlight the risks of each vaccine.
  • fever, typically low-grade
  • redness or swelling where the shot was given
  • soreness or tenderness where the shot was given
  • fussiness
  • headache
  • tiredness or poor appetite
  • vomiting
  • mild rash
  • diarrhea
  • swollen glands

How commonly do they occur?

It depends on the vaccine and side effect, but they range from about 1 in 50 to 1 in 3 people. These side effects are typically mild and only last a day or two. And they don’t cause lasting problems.

While not all possible side effects are mild, those that are more moderate or severe are much more uncommon. Febrile seizures, for example, only happen after about 1 out of 3,000 doses of MMR and some other vaccines. And while scary, febrile seizures, crying for 3 hours or more, or having a very swollen arm or leg, some other uncommon vaccine side effects, also don’t cause lasting problems.

Fortunately, the most severe side effects, including severe allergic reactions, are only thought to happen in less than 1 out of a million doses. And although these types of severe reactions can be life threatening, they are often treatable, just like severe allergic reactions to peanuts. For others, like encephalitis, although they are table injuries, it isn’t clear that they are even side effects of vaccines, since they occur so rarely.

All of these side effects can be reported to the Vaccine Adverse Event Reporting System (VAERS), either by your doctor or yourself.

“No medical product or intervention, from aspirin to heart surgery, can ever be guaranteed 100% safe. Even though we will never be able to ensure 100% safety, we know that the risks of vaccine-preventable diseases by far outweigh those of the vaccines administered to prevent them.”

World Health Organization

In addition to side effects, some other risks of getting vaccinated might include that your vaccine didn’t work, after all, although vaccines work very well, they are not 100% effective. You might also, very rarely, be given the wrong vaccine or the right vaccine at the wrong time.

Many other things, including so-called vaccine induced diseases, aren’t actually a risk of vaccines at all. Remember, autism, SIDS, multiple sclerosis, and shaken-baby syndrome, etc., are not a risk of vaccines.

What to Know About the Risks of Vaccines

Any small risks of getting vaccinated, including side effects that are often mild, are not a good reason to think about skipping or delaying a vaccine, especially when you thoughtfully consider all of their great benefits.
