Strain is more effective than original COVID and the British variant at bypassing the shot, Israeli scientists find, in first-of-its-kind, real-world study
In their study, the prevalence of the South African strain among vaccinated individuals who were infected despite their inoculation was eight times higher than its prevalence in the unvaccinated infected population. Though the number of such infections among the vaccinated was relatively small, the findings indicated that this variant was far more successful in getting through vaccinated individuals’ defenses than other strains.
“Based on patterns in the general population, we would have expected just one case of the South African variant, but we saw eight,” Prof. Adi Stern, who headed the research, told The Times of Israel. “Obviously, this result didn’t make me happy.”
