> FYI, just because you've already had it doesn't mean you can't be an asymptomatic carrier.

That statement defies all science and logic. Either I have immunity, which means the virus can’t survive in my body which means I can’t be a carrier OR I don’t have immunity at which point it’s just as likely to get symptoms as it was the first time.

> Also, some people have had it twice.

There is no actual data to suggest that, only a few self reported cases which scientists have said were far from clear. It’s still regarded as very unlikely and in fact all regions in the world which had a very severe outbreak in March and April haven’t had a second wave at all yet whilst the rest of such countries are currently in the middle of a steep second spike again.
