In two decades of practicing family medicine, I've never seen a patient with measles. But if there was ever a more fertile environment for this age-old contagion to come roaring back in the U.S., this is it. As a measles outbreak in West Texas approaches 100 cases and the national percentage of kindergarten-age children who have received measles, mumps, and rubella (MMR) vaccine has fallen below 93%, vaccine conspiracy theory amplifier Robert F. Kennedy, Jr. has taken the reins as Secretary of Health and Human Services (HHS). In his first week on the job, Kennedy declared his intention to re-evaluate the entire recommended vaccine schedule and indefinitely postponed next week's meeting of the CDC's Advisory Commission on Immunization Practices, which creates the schedule and had been holding uninterrupted meetings to provide guidance for clinicians for the past 60 years. (Oh, and the CDC's National Immunization Survey has been canceled by the so-called Department of Government Efficiency, even if the Epidemic Intelligence Service seems to have received a temporary reprieve.)
This real-life scenario is probably Dr. Adam Ratner's worst nightmare, but it couldn't have come at a better time for his book. Ratner, a pediatric infectious diseases specialist at NYU Grossman School of Medicine, wrote Booster Shots: The Urgent Lessons of Measles and the Uncertain Future of Children's Health to retrace the history of human interactions with measles and explain why our mastery of the science of vaccination hasn't led to enduring eradication of this highly transmissible, damaging, and occasionally lethal infection. In the introduction, Ratner conveys the fury of two grandparents at their adult daughter for refusing measles vaccination for their granddaughter, who becomes one of the first of hundreds of New York City children to be hospitalized for measles in a 2018-19 outbreak:
What happened between those two generations, the vaccine-hesitant mother and her own parents, dumbstruck at the idea of someone opting out of the miracle of vaccination? How did we go from eliminating measles in the United States ... to a massive resurgence in 2019, presaged by smaller blips in the prior years? And should those blips have warned us about some of the problems that we would face with the COVID-19 pandemic - the vaccine hesitancy, the demands for unproven (and sometimes rigorously and scientifically disproven) medications, the distrust of doctors and public health professionals, the underestimation of the new virus's effect on children?
Ratner does an exceptional job describing the epidemiology and virology of measles without watering down the science for a general audience, and the fascinating narrative of the history of measles epidemics over the centuries left me wondering if he had a master's degree in history rather than public health. The most impactful chapters, though, are "Making Nothing Happen," about the laboratory breakthroughs that led to the licensing of the first measles vaccines; and "Amnesia," which juxtaposes the immune system amnesia that often results from measles infection and the human amnesia that causes declines in cases to make people forget why it's necessary to protect children and adults against measles in the first place.
In the concluding chapter, written long before Kennedy was nominated or confirmed as HHS Secretary, Ratner emphasizes the importance of confronting him and other purveyors of vaccine misinformation with the same resolve and attention to detail that have produced the unrivaled medical success of the routine childhood immunization schedule: preventing 508 million cases of illness, 32 million hospitalizations, and 1,129,000 deaths in the U.S. over the past 30 years. This is the perfect book for a very imperfect era, when the future health of our nation very much hangs in the balance. Fortified by Booster Shots, champions of prevention will be able to stand their ground.
