Brazilian Amazon city Manaus achieved ‘herd immunity’, says Imperial College

One of the most affected cities in Brazil during the COVID-19 pandemic, the capital of Amazonas state, Manaus, has achieved “herd immunity”, according to a study by Brazilian researchers in partnership with scientists from Harvard, Imperial College, and Oxford University, in addition to institutes such as Ipea and Fiocruz, reported Folha de São Paulo.

The peak of people immunized in Manaus was in June, with 51.8% of the population showing antibodies. Corrected false negatives, up to 66% the population would have been infected. But that immunity is attached to more than 130,000 infected and almost 4,000 dead.
