In order to have the virus in quantities needed they have to be able to reproduce it in the lab. Grow it.
Like they used chicken eggs to grow cultures for flu virus.
When they first started making potential vaccines for covid. I read a few articles saying that they were having difficulty finding enough of the actual covid virus to make a vaccine. Back in the spring.
I don't know how safe. I'm betting the military has a vaccine for it. I know that if I felt that I needed the vaccine, I would sure as hell take the one the military is handing out. Fuck CVS and Walgreens.
Why would we need a vaccine when it's mild and there are several treatments for it?
I think that the race for a vaccine was never going anywhere and that Trump just made Big Pharma spend buttloads for a vaccine that would never be used. Which is no more than they deserve
The military also plans ahead and makes vaccines itself for bioweapons. Either way tho, Trumps EO said that the military would check safety and distribute so they would have control
