As Iowa parents prepare their kids for the start of school, some are debating what vaccines, if any, they need. Mallya is reminding parents in Iowa that making sure their child is vaccinated is the best way to decrease their risk of getting sick. Mallya says deciding not to have a child vaccinated puts that child — and other children — at risk. In addition to the MMR vaccine, Mallya says there’s a list of inoculations kids should have before returning to class. The Robert Wood Johnson Foundation is the largest US philanthropic foundation focused solely on health.
