Re: Covid-19 antibody tests: a briefing
Thank heavens for an unambiguous criticism of these tests by Dr Pushpa-Rajah (rapid response).
I challenge anyone medically qualified to disagree.
Starting from here, I go on to say:
1. Nobody knows how many persons in any discrete population have had Covid - 19 infection eliciting antibody reaction in the host.
2. Nobody knows how many individuals in such population inhaled Covid -19, or were infected mucosally by Covid-19, and were too strong ( ? Cellular immunity) to develop an antibody reaction, with or without clinical disease.
The implications for the value to be attributed to vaccines will be a matter for conjecture.
