Measles is a highly infectious disease that is easily spread from an infected person by saliva or mucous droplets when coughing, sneezing or talking. Just being in the same room as someone with measles can lead to infection if you are not immunised.
It’s time to jump right into a hot topic you’ll find in parent circles – vaccines. Nothing seems to stir the blood these days more than a good ol’ fashion debate on vaccinating your child. And after a recordbreaking surge in measles cases in 2019, of which the vast majority of cases were unvaccinated children due to parental opposition to measles vaccination, the silent majority of parents who believe in vaccinations are far from silent. A head’s up: since there is so much misinformation out there on vaccines, you need to be armed with detailed, accurate information. And like the rest of this book, that is what you will get in this chapter. The information we provide is based on scientific evidence and solid peerreviewed research. Remember our mantra: show us the science! Your child is too precious to make such important decisions on anything less. This chapter is not based on personal anecdotes, conspiracy theories, “research” done in people’s basements (we are not kidding), or the crusades of B-list celebrities. However, before we get to our take on this debate, let’s go back in time a bit. Well, more than a bit.
How did the human race survive when other early humans didn’t?
Yes, making tools and finding food most efficiently played a big role. But here’s another key element: we built civilizations. And we developed a sense of responsibility – to ourselves and to our society. Every time we respond to a tragedy in our nation – whether it be 9/11, Hurricane Sandy, or the Boston Marathon bombing – we are reminded of how we are not just individuals living in our own little worlds. It’s part of our civic duty to lend a hand and take care of our neighbors. So, what’s this pontificating have to do with vaccines? Again, it is our responsibility to work together as a community...this time, the subject isn’t terrorism or storms, but something that can be just as terrifying: infectious diseases. Consider a bit of history: in the 1890s, people would have seven or eight children in their families and only half of them would survive childhood. Just go to an old graveyard sometime and look at the ages listed on the headstones. Many of the diseases that killed those children are now prevented by vaccination. It’s a fact: vaccinations have increased the life expectancy of our nation’s children. That’s why our grandparents and parents embraced vaccines. Here’s a crucial point: the key to a vaccine’s success is that everyone in the community gets vaccinated. Vaccines won’t work if a large number of folks just choose to opt out of the system and their responsibility. Please keep this in mind as you read about vaccinations. Your decision (and every other parent’s decision) affects your child. And society as a whole. Germs are rather simple creatures...they just look for a new person to infect. They don’t play politics.
The concept of “public health” has been around since antiquity. Obviously, rulers had a vested interest in keeping their subjects healthy so they had a society to rule. Through the years, governments have been responsible for managing numerous programs. The most important advances in public health have been vaccination programs, water purification, and waste disposal/sanitation systems. The only way for public health to work, though, is for all members of the community to follow the same rules.
It took centuries of observation as well as trial and error. (And sometimes, error meant death.) The first real step was describing the disease, in this case, smallpox. Smallpox was a deadly disease that, historically, wiped out entire civilizations. The earliest descriptions can be found as far back as the ninth and tenth centuries among Turks. In fact, “inoculation,” or the infecting of a person with the disease in hopes of introducing a mild form and then creating immunity, was practiced first in Asia. In the 1700s an English aristocrat, Lady Mary Wortly Montagu, was living in Constantinople and learned of the practice of inoculation (known then as variolation). She had her son inoculated and subsequently, brought the practice back to England. At about the same time, an English country doctor, Edward Jenner, made an interesting connection: milkmaids who had been exposed to cowpox (a common disease in cattle at the time) never seemed to get smallpox infections during epidemics. He began to study the idea that vaccinating humans with cowpox virus would make them immune to smallpox. In 1798 he published a paper on his idea and called it “Vaccination.” Not to say, by the way, that Dr. Jenner’s idea was accepted with completely open arms. In the nineteenth century there did emerge a group opposed to vaccination led by Mary C. Hume. See, even the anti-vaccination lobby has been around a long time! Of course, in those days, you could be prosecuted for refusing to vaccinate.1
People were inoculated with a small amount of cowpox virus on their arm. It caused a localized infection at that site (hence, the scar that we forty-somethings and above bear). And true to Dr. Jenner’s hypothesis, it provided protection against smallpox disease. In 1972, the United States stopped vaccinating against smallpox because it was no longer a threat to the population. In 1977, the last case of smallpox occurred in Somalia. In 1980, the World Health Organization declared the world free of smallpox, thanks to a global effort to immunize all children. The success of the smallpox vaccine and other scientific discoveries led to the evolution of many vaccines. These new, safer vaccines are extremely effective in preventing diseases and epidemics that our grandparents and parents can still remember. Why do you care whether I vaccinate my child or not? For starters, I want your baby to be protected. But I also want you to realize that the decision to vaccinate your child impacts the health of other children in the community. Choosing NOT to vaccinate your child is choosing to put your child AND your community’s children at risk. As a parent, you want to make the right choices for your child to protect them. I want you to ask questions. I want you to be informed. And I want you to get your child vaccinated. YOUR decision impacts ALL children. Why? There are two critical points for vaccination to work: 1. You need to be vaccinated. 2. Your neighbor needs to be vaccinated. This concept is called herd immunity. And yes, you are a member of a herd. When 90–95% of “the herd” is protected, it is nearly impossible for a germ to cause an epidemic. Think of germs as rain. Vaccination is a raincoat. Even with a raincoat on, you can still get wet. You need an umbrella, too. The umbrella is “herd immunity.” Those who don’t vaccinate expect someone to share their umbrella when it rains. But society can only buy umbrellas TOGETHER. And raincoats aren’t made for newborns – they need umbrellas! As comedian Jon Stewart once put it, herd immunity is like a zombie movie. You are in an isolated farmhouse and the occupants rely on each other to board up their windows to keep the zombies (germs) out. The zombies get in when some lady from Marin County decides not to board up her windows because she read an article on a wellness blog about the potential health risks of boarding up windows. You can guess what happens! Some parenting decisions have little or no impact on the community at large. Deciding whether or not your child eats organic baby food, goes to preschool, or sleeps in a family bed is entirely up to you – your decision only affects your child. However, your decision whether or not to vaccinate your child affects all our kids. If you are a parent who is considering delaying or skipping vaccinations altogether, please realize the impact of your decision. If more than 10% of American parents choose to “opt out” of vaccines, there’s no question that our entire country will see these horrible diseases of bygone days return. Fortunately, very few parents decide to do this. What is most concerning today is that there are pockets of undervaccinated children. Birds of a feather flock together. Like-minded parents who don’t vaccinate their kids tend to live in the same community and send their kids to the same schools. With lower immunization rates, there is no herd immunity. We have these “Ground Zero” areas to thank for recent measles and whooping cough outbreaks.2
The Good News – While parents are asking more questions, they are still choosing to vaccinate their kids. The most recent Centers for Disease Control and Prevention (CDC) survey (2017) showed 98.9% of U.S. children aged 19 to 35 months had received 1 or more vaccinations. Yes, 98.9%. Despite all the media stories on vaccine “controversy,” only a tiny fraction of parents – about 1% – are choosing to forgo vaccinations.
Vaccines are materials that are given to a person to protect them from disease (that is, provide immunity). The word vaccine is derived from “vaccinia” (cowpox virus), which was used to create the first vaccine in history (smallpox). Modern medicine has created many vaccines. Vaccines PREVENT viral and bacteria infections that used to cause serious illness and death. How do vaccines work? Here is your microbiology lesson for today. Your immune system is your body’s defense against foreign invaders (viruses, bacteria, parasites). Vaccines prepare your body to recognize foreigners without getting infected. A vaccine revs up your immune system to make antibodies (smart bombs with memory) for the signature of a particular germ. So, if your body sees the real germ, voila! You already know how to fight it off. There are three types of vaccinations: inactivated, live attenuated, and inactivated bacterial toxins. • Inactivated vaccines do not contain any living germs. An immune response forms against either a dead germ, part of the germ (recombinant DNA), or a protein or sugar marker that sits on the outer layer of the germ (its signature). Very cool. These vaccines are safe to give to immune-compromised people. The only down side is that several doses of the vaccine are needed to provide full, lifelong protection against disease. Some of these types of vaccines include: influenza, hepatitis A & B, Haemophilus influenzae type B (Hib), pertussis (whooping cough), inactivated polio, pneumococcal. • Live attenuated vaccines are weak forms of the germs that cause infection. An immune response occurs just as if your body had the infection. So one or two doses of vaccine gives you lifelong protection. These vaccines are not given to immune-compromised people because they can make them sick. Examples include: measles, mumps, and rubella, oral polio, smallpox, tuberculosis, varicella (chickenpox), rotavirus. • Toxoids (inactivated bacterial toxins) are vaccines that create a defense against the toxin (poison) that a bacteria germ makes. Examples of toxoid vaccines include diphtheria and tetanus.
Good question. You are probably unfamiliar with most of these diseases since we don’t see them much anymore in the U.S. After you hear about the many successes we’ve had in eradicating disease with vaccination, thank your parents for immunizing you. As you read through the vaccination schedule, note that some diseases are viruses. Antibiotics kill bacteria only. Doctors have no medications to cure the Q viral infections. Doubt the effectiveness of vaccines? Just take a look at the sharp decline of illness and death rates from these diseases since 1950. Here is the link if you want to check it out: www.cdc.gov/vaccines/ pubs/pinkbook/downloads/appendices/E/reported-cases.pdf. Rather amazing, no? Diseases that used to kill thousands (if not hundreds of thousands) now only harm a handful of people – thanks to vaccines
Vaccines are researched extensively for an average of 15 years before being approved for use. A pharmaceutical company conducts medical research trials in a series of stages. Once safety is proven, the vaccine is tested in several thousand volunteers to make sure the vaccine actually works. These volunteers are followed for at least one year to be sure that no serious side effects occur. Nothing in this world is 100% foolproof, including vaccine science. But the research trials that occur before licensing are very rigid. If you think there are a lot of vaccines on the market, imagine how many didn’t make it through the research phase of development. The Food and Drug Administration (FDA) governs this whole process. The FDA is the watchdog for any medication that is sold over-the-counter or by prescription. There are extremely high standards that must be met before any product is allowed for human use. After a vaccine is approved for use, long-term follow-up studies are done to assess for side effects, adverse reactions, and potency over a lifetime.
Given the FDA’s mixed track record, you may be skeptical about trusting the government when it comes to vaccine safety. But in truth, the system is in place to protect consumers. Although conspiracy theorists might disagree, the FDA really is on our side. To improve drug and vaccine safety, the National Academy of Medicine (formerly Institute of Medicine) called for an overhaul of how the FDA works – in the future, the FDA will do more ongoing safety reviews of medicines and make all clinical study results public. This should help boost public confidence in the FDA and vaccine safety.
Simple answer: we’ve been successful inventing vaccines to fight more diseases. It’s one of the important advances in modern medicine – vaccines prevent disease, injury, and death. More vaccines are a good thing! An important point: many of the vaccine-preventable diseases are viruses. These viral infections cannot be treated with medicine once an infection occurs (for example, Hepatitis B). Vaccines that protect against bacterial diseases are often serious ones, and resistant to many antibiotics (for example, Prevnar). And even though the number of shots has gone up, the total load on the immune system has gone down. Today’s vaccines are smarter and better engineered than the shots from a few decades ago. In fact, the total number of immunologic agents in the entire childhood vaccination series today is less than what was in just two vaccines in 1980! Our children are getting smarter, safer vaccines today and better protection than we ever got as kids.
This is a false mantra of the anti-vaccine crowd: they say babies are receiving too many shots (compared to say, 1980) and too soon (infants can’t handle all these shots, they say). So, let’s look at this scientifically. On any given day, your baby is exposed to literally thousands of germs (it doesn’t matter how spotless your house is). Exposing your child to five to eight different germs in the form of vaccines is a spit in the bucket. Young children have better immune responses to vaccines than adults and older children. So they will form adequate immune responses to various vaccines simultaneously. (This is studied extensively before a vaccine is licensed.) Even if your baby got 11 shots at the same time, he would only need to use about 0.1% of his immune system to respond to them.3 Giving several vaccines at once does not damage, weaken, or overload the immune system. Vaccines boost the immune system. Also, the diseases that the vaccines protect against are the most severe in infants and young children. Your doctor wants to get those vaccinations in as safely and effectively as possible. That’s why the timing is so important (and why a staggered or delayed vaccination schedule is a bad idea – more on that in the controversies section of this handout).
Medical science is working on it! There have been a few combination vaccines licensed for use. The largest combination vaccines are Pediarix (DTaP, IPV, Hepatitis B) and Pentacel (DTaP, IPV, Hib). The reason there isn’t just one big shot is that some vaccines are ineffective when they are sitting together in a solution. Your baby may still need more than one shot, but if your doctor uses a combo vaccine, at least it will be fewer shots than if they are all administered separately.
More combination vaccines are on the horizon.
There are four governing panels of experts in infectious diseases that make recommendations for vaccinations. These smart folks include: American Academy of Pediatrics (AAP), American Academy of Family Physicians (AAFP), Advisory Committee on Immunization Practices (ACIP), and the Centers for Disease Control and Prevention (CDC). Because there are several groups involved in this effort, there is some variability in vaccination schedule recommendations.
No! This is a common misconception of parents. Even if your baby has a minor illness, he can still get his shots. We cannot stress how important it is to get your child vaccinated in a timely manner. So don’t let a sniffle or two make you reschedule an office visit for shots. Your child can also get his shots even if he is on antibiotics.
Q Yes, but we wouldn’t advise it. Choosing not to vaccinate is not a riskfree choice. It’s choosing to expose your child to potentially serious infection. It’s also choosing to expose other children in your community to serious, preventable diseases. And if you think your child will be safe because everyone else vaccinates his or her kids, you’d be wrong (and very selfish, we might add). You can also choose not to stop at a stop sign, but we wouldn’t advise it!
Vaccine requirements for school entry vary by state. There is no one consistent policy. As of mid-2019, all 50 states allow vaccine exemptions for medical reasons, 45 states allow exemptions for religious reasons, and 17 states allow exemptions for philosophical reasons.4 After the 2019 measles outbreaks, several state legislatures reconsidered their existing laws for vaccine exemptions. Limiting the exemptions improves vaccination rates and thus protects more children.
No. The diseases we prevent by vaccination are not minor illnesses (this includes chickenpox). For instance, would you rather have your child get meningitis and die or get the vaccine? Getting chickenpox or any other disease the “natural way” is a much greater health risk without any significant benefit. And just think of the discomfort, pain and perhaps serious injury that come with getting any of these diseases. It is true that some vaccinations require a booster dose to keep antibody levels high. That is why we need a tetanus booster every ten years.
That’s an easy one. The diseases would come back. Vaccinations keep us from getting sick from these infections. But all of the infections we protect against are alive and well in our world. As of today, the only disease we have completely eliminated is smallpox. And when it was eliminated, we stopped vaccinating for it. Anyway, it’s a simple fact: when immunization rates drop, epidemics occur. Just look at states with lower immunization rates – their rates of pertussis (whooping cough) are twice the number seen in states with higher percentages of immunization rates. Children whose parents opt out of vaccines face a 23 times greater risk of getting whooping cough.5 In the 2019 measles outbreak, most cases occurred in communities with dangerously low measles immunization rates.
In 1990, low immunization rates led to a measles epidemic of 55,000 cases and over 100 preventable deaths in the U.S. The U.S. saw a measles epidemic again in 2008 – over 90% of these cases were unvaccinated children, two-thirds of which were by parental choice. But a few of the cases were infants who were too young to be vaccinated (and exposed to an infected child in the doctor’s waiting room). You would think we would have learned our lesson, but 2019 was another banner year for measles, with more cases than in the previous 30+ years. This serves as a reminder that vaccine-preventable diseases have not disappeared.
Fever, fussiness, redness, or lump at the site of the injection. Inactivated vaccines cause an immediate immune response. The body mounts a response to the foreign invader as if it were being infected. The result, typically, is a fever within 24 hours of vaccination. Babies sometimes feel like they are coming down with a cold or flu (body aches, pains). Some babies prefer to sleep through the experience; some choose to tell you how they feel (fussiness, crying). All of these symptoms resolve within 24 to 48 hours of vaccination. Live attenuated vaccines (MMR, Varicella) cause a delayed immune response. This occurs one to four weeks after the vaccination is given. Long after the doctor’s visit, your child may wake up one morning and have a fever. This may be accompanied by a rash that looks like measles (pimples) or chickenpox (clear, fluid-filled pimples). The rash can sometimes be dramatic. Both the fever and the rash tell you that your baby is forming an immune response to the vaccination. Babies are not contagious and aren’t too bothered by the rash. You don’t need to call your doctor. This reaction is expected. Redness at the injection site is common. In particular, the fifth booster dose of the DTaP (at age five years) can cause a pretty dramatic area of redness. No worries. We do get quite a few phone calls about it, though! A firm lump may develop at the injection site if some of the fat in the arm/leg gets nicked as the needle goes into the muscle. This is called fat necrosis. It usually goes away within six to eight weeks. It doesn’t hurt. Red flag! If your baby has a fever more than 72 hours after being vaccinated, it’s not from the vaccination. You need to call your doctor. The only exceptions are the MMR and chickenpox vaccines, which typically cause a fever one to four weeks afterwards.
To help reduce fever and discomfort from shots, it’s okay to give your baby acetaminophen (Tylenol) as long as you wait at least four hours after vaccinations are given. The dose is not listed on the package. It says to “consult a doctor.” That’s because doctors don’t want you giving this medicine to a baby three months or younger with a fever without checking in first. Other than with shots, you need to call your doctor about fevers in this age group.
These are called adverse reactions. This is the equivalent of an allergic reaction to a medication – and fortunately, they are all quite rare. With each generation of newer vaccinations, the risk of serious reactions is almost eliminated. Adverse reactions include: 1. Death. 2. Anaphylactic reaction. 3. Encephalitis. 4. Fever-related seizure (convulsions). Both the CDC and FDA keep close tabs on adverse reactions to vaccines via a Vaccine Adverse Event Reporting System (VAERS). Both doctors and patient families may submit a VAERS form if any adverse reaction occurs.
Keep in mind that medical illness reports do not prove an association of a particular illness with a specific vaccination. The job of both the CDC and FDA is to review each report that occurs and see if there is a pattern of subsequent illness after vaccination. VAERS data is publicly available at vaers.hhs.gov. To report a possible reaction, you can download a form at the same site. There is also a Clinical Immunization Safety Assessment Project comprised of six U.S. academic medical centers that evaluates adverse reactions to vaccines. While we would be remiss if we didn’t tell you that vaccinations have some risks associated with them, we want you to remember that the risk of adverse reaction is significantly lower than leaving your baby unprotected. Serious side effects, such as a severe allergic reaction, are known to occur, although very rarely.6 It is estimated that, for every 1 million doses of vaccine, 1 to 2 people will have a severe allergic reaction. That is why you need to watch your child carefully for a few days after their shots and, if you see something that concerns you, call your doctor right away. We agree that a serious adverse reaction only has to happen to one child for it to be heartbreaking. But if we look at the big picture, we can point to the millions of children who might have experienced illness, chronic disability, and death if diseases like smallpox or polio were not controlled by vaccinations.
There are several very specific medical reasons to discontinue or hold off on certain vaccinations. These include: 1. Patient or family member is immune-compromised. 2. Patient had disease (for example, if you’ve had chickenpox, you don’t need the vaccine). 3. Patient has encephalitis or degenerative brain disorder. 4. Patient has allergy to vaccine or to an additive in the vaccine. If your baby has a food allergy to eggs or gelatin, or an allergy to antibiotics (such as neomycin, streptomycin, polymyxin B), notify your doctor before any vaccinations are given. Several vaccines are grown in chick embryo cells and therefore contain a small amount of egg protein: flu vaccine, MMR, rabies, and yellow fever vaccine. The MMR vaccine also includes gelatin. Rabies, MMR, chickenpox, and polio vaccines include several different kinds of antibiotics to prevent contamination of the vaccine itself. Check with your doctor if your child is allergic to any antibiotics. While there is a scant amount of egg protein in the MMR vaccine, it is still safe to give to a person with an egg allergy in your pediatrician’s office. And, although the flu vaccine contains trace amounts of egg protein, beginning with the 2016–17 vaccination season, it is recommended that patients with an egg allergy of any severity can safely be vaccinated with any influenza vaccine product.
