Florida wrote natural immunity into state law this week as GOP lawmakers elsewhere are pushing similar measures to sidestep vaccine mandates.
-
As scientists argue whether a previous bout of COVID-19 voffers the same amount of protection as vaccinations, people turn to the courts to decide.

Scientists don't know whether people who have been exposed to the coronavirus will be immune for life, or if it can infect us again and again, like the common cold.
