Hi Everyone,
I found this interview with an expert (Akiko Iwasaki, PhD) discussing the covid19 virus. Below is an extract of the interview. It basically confirms that all the current publicity about people not showing long term anitbody immunity is not the whole story. Even though the antibodies reduce over time, we do however retain memory of the virus and this triggers a response next time we are exposed to a virus. This is very similar to the regular news in the early days about the covid virus living on surfaces for weeks, however that too wasn't the whole story, the rest of the facts omitted from that news was that the virus on surfaces is in such low quantities it is virtually impossible to catch the virus from surfaces, which has now been shown many times since from official sources. https://forum.diabetes.org.uk/boards/threads/coronavirus-on-surfaces-whats-the-real-risk.88894/
"Topol: One thing that came up recently was this kind of scare whereby some said that the antibody response that was tested in a few different series of patients who recovered from COVID seemed to be abating over time. That may have been a false alarm. Maybe you can put that in context."
"Iwasaki: I don't blame people for becoming worried about this because the longevity of the immune response is what we are counting on for protection of the whole population. That's what vaccines are supposed to do. If you follow COVID-infected patients over time, their antibody levels do seem to wane to some degree within 2-3 months. But that is not a cause for alarm because that's what happens when you get infected or when you become immunized for the first time. The antibody levels peak within the first couple of weeks and then eventually come down over a few months. That's okay because you still have memory B cells specific to that antigen as well as a T-cell immune response to the viral antigen. So the second time you're exposed to the same virus, you can mount a rapid, specific, and robust immune response. It's likely that you won't feel anything the second time you're infected. It will be a pretty mild or asymptomatic infection".

COVID Immune Responses Explained
Akiko Iwasaki explains why waning COVID antibody levels are not a cause for alarm; cytokine 'hurricanes'; herd immunity; long COVID; sex differences in infection; and more.
