The research does not go one to say if the particular activated antibody - obviously produced during a prior other corona virus infection, has protective effects when the person obtains a Covid-19 infection. THAT additional research needs to be done. It could help explain the dominant mass of asymptomatic Covid-19 infections.
Yup good point. Would be good to know if it helped or not. I got tested for covid antibodies because I came down with ‘the crude we called it, back when the coronavirus started, then again a month later, same symptoms, but shorter duration. The test came back negative for antibodies, so no idea what we had. We hadn’t heard of any flues going around at that time, but it was a pretty strong bug whatever it was. Not as strong as others we’ve had, but it was certainly ly miserable. Anyways, I doubt we got covid, as not many folks in our town got it. not sure if we’ve had previous coronavirus or not
Or maybe it just further underscores that the bulk of the “asymptomatic infections” were not that at all, but just the result of the PCR test not only being misused as a diagnostic device, but also turned up to so many cycles that remnants of that weaker coronavirus were found and amplified into fake Covid cases.
