Florida officials are plowing ahead with a proposal to roll back certain vaccine mandates for the state’s schoolchildren. That is after Republican Gov. Ron DeSantis called for the state to become the first in the nation to eliminate all school vaccination requirements. The Florida Department of Health held a public hearing on the policy change in Panama City Beach on Friday. Activists and parents opposed to the mandates heralded the importance of individual freedom. Doctors recalled the children who died of infectious diseases before the advent of vaccines. For generations, the shots have been a cornerstone of public health policy.
