South African COVID variant might evade protection from vaccine, study finds | Washington Examiner
The study, which was published Saturday and still requires peer review, looked at 400 individuals who tested positive for the coronavirus despite receiving at least one dose of the Pfizer/BioNTech vaccine and compared the prevalence of the South African variant, B.1.351, with the same number of people who have not yet received a vaccination.
"We found a disproportionately higher rate of the South African variant among people vaccinated with a second dose, compared to the unvaccinated group," said Adi Stern of Tel Aviv University. "This means that the South African variant is able, to some extent, to break through the vaccine's protection."
Not only could the variant "break through" protections offered by the Pfizer vaccine, but it uniquely affects those who have been vaccinated (around eight times higher) than those who have not received the vaccine — 5.4% to 0.7%.
