It has been suggested that a coronavirus variant circulating in Brazil may reinfect people who survived infections with earlier versions of the coronavirus. The variant that emerged in Brazil, known as P.1, carries a mutation that is already known to make a variant prevalent in South Africa harder to treat with antibodies and harder to prevent with available vaccines. New data suggests that in several recovered patients, immunity to previous versions of the virus will not afford immunity to P.1. 

In a pre-print edition of the article published in the Lancet journal it was concluded that, “lower neutralization capacity of SARS-CoV-2 antibodies and partial immunity against new variants suggests that reinfection could occur in convalescent or even vaccinated individuals.” It has also been reported in the study that among every 100 survivors of COVID-19 due to earlier virus versions, 25-to 60 could become reinfected if exposed to the P.1 variant because their antibodies could not protect them.
