STAT (5/3, Branswell) reported that as U.S. health officials put “all they have into extinguishing measles outbreaks,” there is “a growing amount of tinder afoot, a fact that will make it increasing difficult to battle these blazes, experts fear.” While “the percentage of children who have received one or more doses of measles-containing vaccine has remained relatively stable,” over the past few decades, “the overall size of the population that is either unvaccinated or undervaccinated has been growing.” According to the article, “with each cohort of kids born to parents who distrust or fear vaccines, the number of people susceptible to the measles virus expands,” and “at the same time, there is a growing population of adults who were children in the early days of measles vaccination whose immunity may have worn off.”
