A little optimism from the NYTimes
Quote:
But declining antibodies, as indicated by commercial tests, don’t necessarily mean declining immunity, several experts said.
“Whatever your level is today, if you get infected, your antibody titers are going to go way up,” said Dr. Michael Mina, an immunologist at Harvard University, referring to the levels of antibodies in the blood. “The virus will never even have a chance the second time around.”
A small number of people may not produce any antibodies to the coronavirus. But even then, they will have “cellular immunity,” which includes T cells that learn to identify and destroy the virus.
“This means that even if the antibody titer is low, those people who are previously infected may have a good enough T-cell response that can provide protection,” said Akiko Iwasaki, an immunologist at Yale University.

Hope that’s right. That would be great news.
