More parents are opting out of school shots for their children. In eight states now, more than one in 20 public school kindergartners aren’t getting all the vaccines required for attendance, an Associated Press analysis found.
That growing trend among parents seeking vaccine exemptions has health officials worried about outbreaks of diseases that once were all but stamped out.
Take measles, for example. It can lead to pneumonia, encephalitis and death. Since 2000, one in every 250 Americans who got measles died.
The measles vaccine is so effective, 99.9% of those who get vaccinated gain immunity, said Geoffrey Swain, associate professor at the University of Wisconsin School of Medicine and Public Health and chief medical officer for the Milwaukee Health Department.
Many children cannot get the measles vaccine, though, because they aren’t old enough – the first dose of vaccine is recommended between 12 and 15 months. Or, they have medical issues or families with religious beliefs that leave them unprotected and susceptible to measles through no fault of their own, Swain said.
