You’re messing not just with your own child’s health but the health of all the kids – and adults – around them.
A new study looks at incoming kindergartners in California, and finds that the lack of vaccination is threatening herd immunity in some schools, and that some measures of risk have doubled in just three years.
Using data from 2008 to 2010, the authors found some worrying trends. Over just two years, the statewide interaction index increased by 25 percent in this short time. That means far more students are coming in contact with peers who are unvaccinated—a serious risk, since vaccines are not 100 percent effective.
