Study on SARS-CoV-2 antibodies levels following infection don’t prove that recovered patients are protected from reinfection
Both SARS-CoV-2 infection and COVID-19 vaccination lead the body to produce antibodies that provide immunity to COVID-19. Data indicate that SARS-CoV-2 antibodies may last up to 20 months following infection. However, no data is available to determine what levels of antibodies are correlated with protection from reinfection. The main drawback of infection-induced immunity is that SARS-CoV-2 infection can lead to severe disease and even death, whereas vaccines are safer and effective and can also enhance infection-induced immunity.Thus, they remain the strategy of choice.
