Just had a thought. What if we took a insignificant amount of the virus and injected it into people. This would allow them to develop antibodies so that if they do become exposed they are ready to fight it.
Probably safer then just exposing people to the virus. Could also do it to enough people that it virtually eradicates the virus.
Just an idea. We would also have to do a bunch of testing and have a bunch of regulations around it. Just to prove there isn't any unwarranted side effects.
