With a brief memo, Florida Surgeon General Joseph Ladapo has subverted a public health standard that's long kept measles outbreaks under control.On Feb. 20, as measles spread through Manatee Bay Elementary in South Florida, Ladapo sent parents a letter granting them permission to send unvaccinated children to school amid the outbreak.
For this reason, government officials have occasionally mandated vaccines in emergencies in the past. For example, Philadelphia's deputy health commissioner in 1991 ordered children to get vaccinated against their parents' wishes during outbreaks traced to their faith-healing churches.
