A new study has found that there is a link between the severity of Covid-19 and the levels of antibodies patients carry after recovering from the virus.
The research conducted by Stanford Medicine shows that Covid-19 antibodies preferentially target a different part of the virus in mild cases than they do in severe cases. But all antibodies significantly decrease within months.
The team of researchers studied 254 people who were asymptomatic, had mild, or severe Covid-19. They were identified at the Stanford Health Care Clinic.
