“Sars-Cov2 immunity persists for months”


“Neutralizing antibodies against Sars-Cov2 persist for months in the vast majority of people who have recovered from Covid-19”. This is the good news highlighted by Guido Silvestri, virologist at Emory University in Atlanta, who posted on Facebook “the results of an impressive study published today in the journal ‘Science’ with case histories of over 30,000 subjects, the largest ever so far”.

“This is an extremely important confirmation – he comments – of similar results obtained by other groups in smaller series. Above all, the study confirms the observation that re-infections with Sars-Cov-2 are very rare and supports the hypothesis that robust herd immunity to the virus is forming in the areas most affected by the first wave of the pandemic “, Silvestri underlines, exhorting to “disseminate this important research as due”.
