1 year old might have covid.

So I think my 1 year old might have covid. Gonna call the doctor tomorrow. But I'm wondering is there anything the doctor can even give my 1 year old. Do they give the vaccine to kids that young? Can they give him anything to help him feel better right away? How long will it be before he's back to his normal self?

Did anyone else go through this with your young kids? Advice?
