Brazilian coronavirus variant could cause reinfection in up to 61% of people 

The P1 variant was found to be 1.4 to 2.2 times more transmissible than other variants in Manaus, and was found to evade 25% to 61% of protective immunity from previous infection.

The Manaus variant of coronavirus, detected in Ireland last month, could cause reinfection for between 25% and 61% of people who have previously had Covid, a new study suggests.

Research on the P1 variant among people living in the Brazilian city of Manaus found potentially high levels of reinfection, and that the variant was more transmissible than the original pandemic strain.
