Pfizer Vaccine May Put People at Higher Risk for COVID Variants, Israeli Study Shows

Israeli researchers found people who received two doses of the Pfizer vaccine were eight times more likely to be infected with the South African variant, and people who received one dose of the vaccine were more likely to get the UK variant.

A new study by Israeli researchers found that a South African variant of COVID may put people who have been vaccinated with the Pfizer-BioNTech vaccine at higher risk of breakthrough infection compared to unvaccinated people.

The study also showed an increased incidence of the UK variant in those who received one dose of the Pfizer shot.

The study, released April 10, reviewed the positive COVID-19 test results of 800 people — 400 people who tested positive for COVID 14 days or more after they received one or two doses of the Pfizer vaccine against 400 unvaccinated people to see if those vaccinated were more likely to be infected with the UK or South African variant compared with unvaccinated individuals.

The South African variant, B.1.351, was found to make up about 1% of all COVID cases across all the people studied, according to the study by Tel Aviv University and Israel’s largest healthcare provider, Clalit.

But among patients who had received two doses of the vaccine, the variant’s prevalence rate was eight times higher than in those unvaccinated — 5.4% versus 0.7%, Reuters reported.

The research suggests the vaccine is less effective against the South African variant, compared with the original COVID variant and a variant first identified in Britain that had comprised nearly all COVID cases in Israel, researchers said.

“We found a disproportionately higher rate of the South African variant among people vaccinated with a second dose, compared to the unvaccinated group,” said Tel Aviv University’s Adi Stern, who headed the research. “This means that the South African variant is able, to some extent, to break through the vaccine’s protection.”
