  • Brazil's P1 coronavirus variant mutating, may become more dangerous: study

    RIO DE JANEIRO (Reuters) - Brazil?s P1 coronavirus variant, behind a deadly COVID-19 surge in the Latin American country that has raised international alarm, is mutating in ways that could make it better able to evade antibodies, according to scientists studying the virus.

    Research conducted by the public health institute Fiocruz into the variants circulating in Brazil found mutations in the spike region of the virus that is used to enter and infect cells.

    Those changes, the scientists said, could make the virus more resistant to vaccines - which target the spike protein - with potentially grave implications for the severity of the outbreak in Latin America?s most populous nation.

    ?We believe it?s another escape mechanism the virus is creating to evade the response of antibodies,? said Felipe Naveca, one of the authors of the study and part of Fiocruz in the Amazon city of Manaus, where the P1 variant is believed to have originated.
