J&J’s COVID Vaccine Produces Virtually No Antibody Protection Against Omicron

A new study found that Johnson & Johnson’s COVID vaccine produced virtually no antibody response to the Omicron variant.  South African virologist Penny Moore found that a key measure of antibody levels fell fell from 303 against the original strain to undetectable levels against Omicron in those with the J&J shot.  Among those who received the Pfizer shot, the antibody measure, called geometric mean titers, fell from 1,419 against the original coronavirus strain to 80 against Omicron.  “Omicron does indeed exhibit substantial immune escape from antibodies,” she said.  “The situation, I think, is even more alarming for the J&J vaccine — there was no detectable neutralization in our assay.”
