Of course, I don’t think it would do anything for someone already infected with SARS-CoV-2 (Covid-19 or “Rona”). But wouldn’t it offer some level of innoculation or protection to someone not yet infected with Covid-19? If not, why not?

My limited understanding is that the immune system works better at fighting off a new virus based on how similar it was to a virus it has already fought off in the past (or vaccinated against).

So maybe exposure to other coronaviruses reduces the severity of a cv-19 infection?

The shutdown was to prevent an overload of our medical system ("flatten the curve"). That didn't happen, so it's time to call it off. At some point, we will ALL be infected to certain degrees, no matter what steps we take, so let's get on with it and take care of that small percentage who get a bad reaction.
