It's funny that they say only 20% have antibodies when some studies have shown over 30% of the general population have antibodies for Covid19. Not only that, but they took some blood samples from a couple years ago and found that even some of those samples tested positive for Covid19 antibodies. What this means is that the ancestors of this virus have been circulating in the population for years already and that about a third of the population has partial immunity. Then they're saying that of those infected, only 20% have antibodies? I mean, did they cherry pick only AIDS patients for this study or something? Something stinks.

Yes, the population can have antibodies while testing those who "tested positive" have 20%. If you have 1000 people, and then 300 of them have antibodies, ok. They weren't tested "positive" in the PCR test or by some doctor who said "you have COVID-19". If you take 100 people who are allegedly COVID-19 positive, and check their antibodies, then you get 20% of the 100 that have antibodies (20 people). It doesn't negate 30% of the 1000 from having antibodies. It's also possible the antibody tests from before were picking up previous covid antibodies...
Correct. I think I may have confused these numbers because the one study from NY said there were 30% positive. I think the point of the article I mentioned was that there are ancestors for SARS-CoV2 which many people already have antibodies for, meaning that the novel nature of it is called into question. More than likely it mutated from something we already have circulating through the population that previously may have been identified as a cold or flu based on symptoms.
"they took some blood samples from a couple years ago and found that even some of those samples tested positive for Covid19 antibodies". You got sources on that? I just want to read up on it
Okay, well I poked around and I can't find a link to the study I was thinking of. Maybe I saw it somewhere other than facebook, but I did find this YouTube video doing an analysis on the cross-reactivity of antibodies for other viruses being cross-reactive with SARS-CoV2. Kevin McKernan is a genomics expert who worked on the human genome project back in the '90s and early '00s. He goes over a lot of the theory behind why many don't get sick when exposed to Covid-19. https://www.youtube.com/watch?reload=9&v=2SfXZa7-JKM&feature=youtu.be&fbclid=IwAR0uce2be0mt4pjp1nLt-2q_2omt7shNiI6wjZkcKJ1qW8Ho34SGNW0kmeE
Sure. I originally came across it on FB so it might take me a bit to find it, but I'll track the link down.
