Researchers Debate Infecting People on Purpose to Test Coronavirus Vaccines

Researchers Debate Infecting People on Purpose to Test Coronavirus Vaccines | 01 July 2020 | One way to quickly see if a coronavirus vaccine works would be to immunize healthy people and then deliberately expose them to the virus, some researchers are suggesting. Proponents say this strategy, called a human challenge trial, could save time because rather than conducting tests the usual way -- by waiting for vaccinated people to encounter the virus naturally -- researchers could just infect them.
