HOW TO INOCULATE AGAINST ANTI-VAXXERS
The World Health Organization has ranked vaccine hesitancy — the growing resistance to widely available lifesaving vaccines — as one of the top 10 health threats in the world for 2019. That news will not come as a surprise in New York City, where the worst measles outbreak in decades is underway. Nor in California or Minnesota, where similar outbreaks unfolded in 2014 and 2017, respectively. Nor in Texas, where some 60,000 children remain wholly unvaccinated thanks in part to an aggressive anti-vaccine lobby.
Leading global health threats typically are caused by the plagues and perils of low-income countries — but vaccine hesitancy is as American as can be. According to the Centers for Disease Control and Prevention, the percentage of children who are unvaccinated has quadrupled since 2001, even though the overall utilization of most vaccines remains high. More than 100,000 American infants and toddlers have received no vaccines whatsoever, and millions more have received only some crucial shots.
It’s no mystery how we got here. On the internet, anti-vaccine propaganda has outpaced pro-vaccine public health information. The anti-vaxxers, as they are colloquially known, have hundreds of websites promoting their message, a roster of tech- and media-savvy influencers and an aggressive political arm that includes at least a dozen political action committees. Defense against this onslaught has been meager. The CDC, the nation’s leading public health agency, has a website with accurate information but no loud public voice. The U.S. Surgeon General’s office has been mum. So has the White House — and not just under the current administration. That leaves just a handful of academics who get bombarded with vitriol, including outright threats, every time they try to counter pseudoscience with fact.
The consequences of this disparity are substantial: a surge in outbreaks of measles, mumps, pertussis and other diseases; an increase in influenza deaths; and dismal rates of HPV vaccination, which doctors say could effectively wipe out cervical cancer if it were better utilized. But infectious disease experts warn that things could get much worse. Trust in vaccines is being so thoroughly eroded, they say, that these prevention tools are in danger of becoming useless. The next major disease outbreak “will not be due to a lack of preventive technologies,” Heidi Larson, a professor at the London School of Hygiene and Tropical Medicine, writes in the journal Nature, but to an “emotional contagion, digitally enabled.”
Thwarting this danger will require a campaign as bold and aggressive as the one being waged by the antivaccination contingent.
Here’s how to get started.
Get tough. After the 2014 California measles outbreak, the state eliminated nonmedical exemptions for mandatory vaccinations. After a similar outbreak in Michigan, health officials there began requiring individuals to formally consult their local health departments before opting out of otherwise-mandatory shots. In both cases, those tougher policies drove up vaccination rates. Other states ought to follow that lead, and the federal government should consider tightening restrictions around how much leeway states can grant families that want to skip essential vaccines.
Be clear. Vaccines, to some extent, are victims of their own success. In the United States especially, they’ve beaten so many infectious foes into oblivion that hardly any practicing doctors, let alone new parents, remember how terrible those diseases once were. An effective pro-vaccine campaign needs to remind us: Vaccines prevent 2 million to 3 million deaths globally each year. It’s also OK to get out of the gray zone. Scientists, especially, are uncomfortable with black-and-white statements, because science is all about nuance. But, in the case of vaccines, there are some hard truths that deserve to be trumpeted. Vaccines are not toxic, and they do not cause autism. Full stop.
Know the enemy. The arguments used by people driving the anti-vaccination movement have not changed in about a century. Those arguments are effective because they are intuitively appealing — but they are also easily refutable. An effective pro-vaccine campaign would confront them directly, over and over, for as long as it takes. Yes, there are chemicals in vaccines, but they are not toxic. No, vaccines can’t overwhelm your immune system, which already confronts countless pathogens every day.
Enlist the right support. Some doctors and scientists have referred to “uneventful vaccination” as “The Greatest Story Never Told.” Although they may not spread on the internet like the stories of terrible mishaps that anti-vaxxers traffic in, these far more common tales of inoculation without incident can be a powerful elixir for a nervous new parent. The best ambassadors of these stories are likely to be parents themselves. Surveys suggest that pro-vaccine families are often eager to help counter misinformation, but they don’t know where to start. If health officials corralled those families and trained them in the basics of vaccine science, they might succeed where official voices sometimes fail.
