Interesting ethical conversation regarding the future vaccine:
Researchers Debate Infecting People on Purpose to Test Coronavirus Vaccines

The technique, called a human challenge trial, has been used to evaluate other vaccines.
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.
Challenge trials have been used to test vaccines for typhoid, cholera, malaria and other diseases. For malaria, volunteers have stuck their arms into chambers full of mosquitoes to be bitten and infected. But there were so-called rescue medicines to cure those who got sick. There is no cure for Covid-19.
For both ethical and practical reasons, the idea of challenge trials for a coronavirus vaccine has provoked fierce debate.
