1. No-one knows what a Covid-Infection does to you in the long term.
2. We know that a Covid-Infection in the short term can have devastating effects.
3. The point is to dampen the epidemiological course by dampening the spread. The point is not to overload the hospital system. The point is to reduce the risk of spreading by considerably reducing the risk of infection when getting in contact with the virus. The point is to reduce the amount of virus replication in your body to dampen the emergence of mutations.
