The P1 SARS-CoV-2 variant which was first identified in Brazil may be more than twice as transmissible as non-P1 lineages and it may lower protective immunity from non-P1 variants 21 to 46 according to a study published yesterday in Science.

Different SARS-CoV-2 lineages in each COVID-19 episode. Sometimes called the Brazil variant P1 is feared to be. P2 another variant similar to P1 was also discovered in Manaus but has fewer deadly mutations.
