The coronavirus variant first discovered in South Africa is able to evade some of the protection of the Pfizer-BioNTech vaccine, according to a new Israeli study, which has not yet been peer-reviewed. 6park.com

Researchers at Tel Aviv University and Clalit, the largest health-care organization in Israel, examined nearly 400 people who had tested positive for Covid-19 after receiving at least one dose of the vaccine. They compared them to the same number of people who were infected and unvaccinated. 6park.com

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. 6park.com

“Based on patterns in the general population, we would have expected just one case of the South African variant, but we saw eight,” Professor Adi Stern, who headed the research, told The Times of Israel. “We can say it’s less effective, but more research is needed to establish exactly how much.” 6park.com
