Ioannidis is a Covid skeptic (i.e. Flubro), but his conclusion seems in the ball park. The problem with seroprevalence studies is that it assumes that those who have an asymptomatic infection will acquire the same level of protective immunity as those who have a “real” case of Covid - who actually get sick. If the asymptomatic get immunity then Covid is much less dangerous. If the asymptomatic don’t get immunity, then they will eventually get a real case of Covid and run a substantial risk of death. We have an overall case fatality rate of about 1.5% in the US. Saying the “real” fatality rate is lower is like saying the lung cancer mortality rate is actually lower because lots of people have lung cancer without knowing it and it goes away. I don’t see what the point is of arguing about the fatality rate of people who don’t even get sick. But I would like to know whether the asymptomatic infected get immunity.
Interesting.
Thank you.
