FROMA HARROP: What happens if anti-vaxxers just face the consequences?

“Medical Freedom” crusaders are trying to end vaccination requirements for schoolchildren. Places where they succeed, epidemiologists warn, will, for starters, become overrun with measles, a disease that was virtually eliminated thanks to vaccines.
