Hello, I have a question. My girlfriend told me that Europe has been creating strange farms where many people with Covid lived there. The purpose of this was to know and study the maximum stage of the virus to create a vaccine. I tried to search it on the internet, but there was nothing there. I thought it would be interesting to ask other people besides her. On the other hand, I think it is unethical to study a virus that way and I think many people think the same way, and therefore would not be in an article or something like that.
