PFIZER VACCINE: may NOT be enough for the SOUTH AFRICAN VARIANT of COVID. THIRD DOSE HYPOTHESIS
Hypothesis of a THIRD DOSE to increase the protection from VARIATIONSA new discovery, the result of a careful and precise study, has brought to light the possibility that the South African variant of coronavirus be able to “pierce”, at least partially, the vaccine-induced shield Pfizer-BioNTech.
One revealed it Israeli study which is also reported by the newspaper Corriere della Sera. Researchers fromTel Aviv university andClalit institute they examined 400 people positive for COVID-19 despite a dose of the vaccine and compared them to the same number of equally infected, but unvaccinated people. Scientists noted that the prevalence of the South African variant among those who had received two doses of serum it was about eight times higher compared to the unvaccinated population.
“We would have expected only one case of the South African variant, we found eight”, the professor said Adi star, which led the research, to the newspaper The Times of Israel. Hence the South African variant “is capable of violating vaccine protection”, although more studies will be needed to confirm the hypothesis. The research is bound to raise questions about another real-world study conducted by Pfizer which he concluded as the vaccine mRNA keep a protection of at least six months even against the variant.
The variants, we remember, worry all governments, so much so that the pharmaceutical companies have moved to study the hypothesis of one third dose to increase protection. In fact, the hypothesis that they are necessary is gaining ground periodic boosters of the vaccine especially among the elderly population as it already happens with the flu. Moderna also developed a vaccine against the South African variant and delivered the doses to National Institutes of Health for the start of the clinical study.
