A study in Israel claimed that the Pfizer and Biontech vaccine was found to be less effective than other vaccines on the South African Corona Variant found in South Africa. . Research has said that the South African corona variant was found to be able to penetrate the protection given by two doses (Dose) of the Pfizer vaccine to some extent. However, it is not clear yet how much the efficacy of the vaccine has decreased from the variant.
This research was released on Saturday, which compared about 400 people. In this, those who were found to be corona positive after receiving one or two doses of the vaccine two weeks or earlier were compared to those who had not received the vaccine.
Less effective vaccine against SA variant
A study conducted by Tel Aviv University and Israel’s largest healthcare provider Clalit found 1 percent of all corona cases included in the South African variant B.1.351 study. According to the study, the prevalence rate of the corona variant in patients taking both doses of the vaccine was eight times higher than in patients not taking the vaccine, 5.4 percent versus 0.7 percent.
Researchers said that this vaccine is less effective against the original Corona virus variant and the South African variant than the earliest UK variant. Adi Stern of Tel Aviv University said in research that we found disproportionately higher rates of South African variants among people who received the second dose of vaccine than the non-vaccinated group.
The company refused to comment
This means that the South African variant has been able to penetrate the protection given by the vaccine to some extent. However, researchers have warned that a small sample of people infected with the South African variant was included in the research due to rarity in Israel. He also said that the aim of the research was not to reduce the overall effectiveness of any vaccine. Pfizer and BioNotech company have not made any comment about this at the moment.
