Vaccine fears: What can you do?
An infant girl suffering from pertussis, a vaccine-preventable disease,
What’s not to fear directly about vaccines? There’s a needle that someone pokes into your child. Your child screams. You tense up. What’s in there? you wonder. Viral or bacterial bits that, in ways that are mysterious to a non-immunologist, will keep your child well when intuition seems to say they ought to make your child sick.
Needles, screaming, microbial bits…these naturally would make any parent blanch. The number of vaccines has added to the fear for at least a decade, leading to non–evidence-based calls to “spread out” the schedule or reduce the number of vaccinations.
In fact, the evidence supports the schedule as it’s recommended.
The fear of vaccination is not new. Since Edward Jenner and his cowpox inoculation at the turn of the 19th century, people have latched onto the fear of the known—those needles!—and unknown—what’s in those things?
What might be considered the first anti-vaccine cartoon appeared in response to Jenner’s proposed inoculation of cowpox to combat smallpox.
The vision of cows growing out of arms is comical, but the reality of possible side effects from today’s vaccines can lead some parents to keep their children away from the doctor’s office. Indeed, this anxiety has done so since the days of the 19th century anti-vaccination leagues, aligned against the widespread use of Jenner’s smallpox vaccine.
The vaccine wars in those days were just as bitter and divisive as they are today, including an 1885 march in England in which anti-vaccination forces carried a child’s coffin and an effigy of Jenner himself. Today’s most fanatical crusaders against vaccines may not carry coffins or effigies, but death threats against those who promote vaccines for public health are not unknown.
The fact that the vast majority of parents overcame those fears and had their children vaccinated has led to some of the greatest public health successes of the 20th century. Thanks to the willingness of people to participate in vaccination programs, smallpox disappeared and polio became a thing of the past in much of the world. Indeed, people in those eras knew, often from personal experience, what these diseases could do—maim and kill—and the fear of those very real outcomes outweighed fears of the vaccinations.
But today, we’re different. In the United States, most of us under a certain age have never witnessed a death from diphtheria or tetanus or smallpox or measles. We haven’t seen a child drained of life as a rotavirus rapidly depletes the molecules she needs to live. Many of us have not witnessed the sounds of pertussis, the vomiting, the exploding lungs in an agony of infant death. Why? Because of vaccines.
This very success has, ironically, led to the resurgence of fear and misgiving about vaccines. No longer weighed against anxiety of death or disability from disease, the fear of vaccines now aligns against the bright picture of a nation of children largely free of life-threatening illness.
Without the collective memory of days when children played on the playground one day and died the next of vaccine-preventable disease, the calculus of parental fear pits only the side effects of vaccines against the healthy child. Vaccination requires intentional agency—parental agreement—to impose on that healthy child the very small risk that vaccines carry. Some parents simply are not comfortable either with that intentionality or that risk.
Feeding this reluctance is the explosion of Internet sites that warn against vaccines or disseminate incorrect information about them. The Centers for Disease Control and Prevention (CDC) has provided abundant information about vaccines, including a page devoted to countering erroneous information with facts.
This information will not move the fiercest anti-vaccine groups that lump the CDC in with pharmaceutical companies and others in an alleged conspiracy to harm millions via a money-making vaccine industry. However, it certainly helps concerned parents who simply seek to calm fears, weigh evidence, and make an informed decision about choosing vaccines over the life-threatening illness and compromised public health that result when people don’t vaccinate.
Indeed, these threats to public health have grown considerably with recent large outbreaks of measles and pertussis, including a growing measles outbreak in Europe involving more than 26,000 cases of measles, more than 7000 hospitalizations, and nine deaths as of this writing. The growing threat has led to calls for more stringent requirements for childhood vaccines, including dropping exemptions and requiring that all children be vaccinated over parental objections. This tactic likely would increase vaccination rates among children attending school.
But instead of strong-arming parents into having their children vaccinated, what we really need is a two-fold approach to education. First, we need sober, non-sensationalist reporting from the news media about vaccine-related stories, including stories about side effects, research, and court cases. These articles—and their sensational headlines—are in all likelihood among the prime drivers of the rumor mill against vaccines.
Second, when parents read these stories and turn to a medical professional for input, that input must come as part of a two-way communication between the health professional and the parent, not in lecture format or as patronizing. A little, “I understand your concerns because I’ve had them, too, but here’s what I know that gives me confidence in vaccines,” is considerably better than, “Your child has to be vaccinated, or you can get out of my office.” The onus is on parents to ask with open minds and an understanding that the medical professional in front of them has likely devoted considerable time to gaining the education and expertise necessary to address their questions. Health care isn't a competition about who knows more. It's about evidence-based health practices.
As centuries of history attest, no efforts will completely eradicate vaccine fears. Motivations fueling anti-vaccine sentiment that go beyond information gaps range from personal economic benefit to a desire to out-expert the experts to the inertia of fear.
But a careful and persistent information campaign and outreach efforts from medical professionals in the trenches may help keep vaccination rates sufficiently high. Parental investment in gaining information from trained professionals and making decisions based on facts rather than fear is also an indispensable component. To ensure adequate rates requires either these efforts or a resurgence of the deadly diseases that have graphically demonstrated the real balance of the threats at issue here.
Which one would we rather have?
