Covid variant from South Africa was able to ‘break through’ Pfizer vaccine in Israeli study

The researchers found the prevalence of the variant from South Africa, known as B.1.351, among patients who received two doses of the vaccine was about eight times higher than those who were unvaccinated. The data, published online over the weekend, suggest the B.1.351 is better able to "break through" the protection of the vaccine than the original strain, the researchers wrote in the study.
