RE: The real question is not if it prevents them from getting Covid-19, but rather if they feel any ill effects of Covid-19, and do they recover?
I have to disagree with you. Not feeling the effects does not mean you are not a carrier. In fact, it has been argued that MOST of those who are infected are asymptomatic but INFECT other vulnerable people nonetheless.
PREVENTION (as in having a sort of vaccine effect ) is IMPORTANT. If you don’t get it, you don’t infect the vulnerable.
Well you can disagree all you want, but the fact is that lupus patients have immunity issues, so it is important. Also how quickly they recover, if they do, is also important.
