Thank you.
A recent lab study suggested that the South African variant may reduce protective antibodies elicited by the Pfizer vaccine by two-thirds.
Moderna just published a correspondence in the New England Journal of Medicine with data that showed a sixfold drop in antibody levels versus the South African variant.
Is there any anticipation that this reduction in protective antibodies will render the Pfizer and Moderna vaccines ineffective against the B.1.351 variant?
