Individual SARS-CoV-2 neutralising antibody immunity lasts from days to decades

(Duke-NUS Medical School) Study shows that antibody longevity varies widely from 40 days to as long as several decades and not everyone who has recovered from COVID-19 is immune from reinfection. Individuals with low levels of neutralising antibodies may still be protected if they have robust T-cell immunity. Blood tests and a computer algorithm suggest annual vaccinations might be needed for some individuals to prevent future outbreaks of COVID-19.
