>Disturbing new revelations that permanent immunity to the coronavirus may not be possible have jeopardized vaccine development and reinforced a decision by scientists at UCSF and affiliated laboratories to focus exclusively on treatments.
>Several recent studies conducted around the world indicate that the human body does not retain the antibodies that build up during infections, meaning there may be no lasting immunity to COVID-19 after people recover.
>The latest bad news came from scientists at King’s College of London, whose study of 90 COVID-19 patients in the United Kingdom found antibody levels peaked three weeks after the onset of symptoms and then dramatically declined.
>“Waning antibodies affect vaccine development,” said Shannon Bennett, the chief of science at San Francisco’s California Academy of Sciences. “Where natural immunity doesn’t really develop or last, then vaccine programs are not likely to be easily successful or achievable.
