I had seen a report a couple of weeks ago suggesting that many people who tested positive for COVID-19 actually tested negative for the COVID-19 antibodies 4-6 weeks after they recovered. One of the reasons people like Drs. Fauci and Birx are concerned about a flare-up later in the year is that there may be NO permanent immunity to COVID-19 after recovery.

Perhaps they could store some of their own plasma for their own later use as convalescent plasma to treat any flareup. Would be a perfect match, I would think.
That's funny. Why would they bother with convalescent plasma treatment then if there's no immunity response in recovering patients?
There are many plausible reasons for this. First, the acute antibody response would be IgM antibodies, which would show recent or current infection and are short-lived. It is the IgG antibodies that are the longer lasting ones, produced by cells with memory. It may be that these antibodies require a second exposure to the virus to kick in.
It could also be a false positive for COVID-19 which has also been reported, especially if these were some of the earlier tests that were more questionable.
Like many on this thread I too was sick as a dog in late November/early December 2019. As were many of my friends (most for three weeks). We all put it off to the ‘seasonal flu’.
I was posing a question to one of my friends who is a researcher / writer for a science mag asking how I could be tested to see if I had been exposed to COVID-19 and maybe had built up immunity.
She replied: The virus apparently prompts varying levels of antibodies in different people, and they start to fade fairly quickly.

More likely, they are familiar with history. Almost every flu pandemic has had at least two waves and usually three. The misnamed Spanish flu had a mild wave in the spring, then a very lethal wave in the autumn, and then another that was in between in 1919. Some even postulate a fourth wave in 1920. My father lost his mother in early 1920 to what he believes was the Spanish flu.
