Effect of BioNTech Vaccine on Omicron Explained for the First Time

Although it was seen in a small number of people at that time, which appeared about 2 weeks ago, which caused countries to sign on travel restrictions decisions. About the Omicron variant works in progress. One of the most curious things about the new variant was whether the vaccines we currently use could resist the variant. To answer this, a study showed for the first time the effect of the coronavirus vaccine developed by BioNTech and Pfizer on Omicron.

In the study carried out at the African Health Research Institute and still awaiting peer review, 6 of them had previously experienced coronavirus. 14 blood samples were taken from 12 people. In the study, compared to the original version of the virus The BioNTech vaccine Roughly 40 times greater reduction in antibody levels was discovered. Although this rate is frightening, Alex Sigal, who carried out the study, Omicron still hasn’t completely defeated the vaccine., expressed that it is important to be vaccinated against the new variant.

Will Omicron require additional vaccinations?

But the marked reduction in antibodies raised the question of how effective the vaccine protection against Omicron would be, as well as how durable it would be. Sigal has a good and empowering comment on this subject. Additional vaccination will reduce the risk of infectionstated that there should be those who do not have additional vaccinations.

A study was also conducted in Sweden

Shortly after Sigal announced the results of her work with her team, Sweden’s Karolinska Institute also published the results of its own study. This study compares to the study in South Africa. lower level of antibody reduction it was showing. According to the study with 17 blood samples pending evaluation, such as the study in Africa, the reduction in antibody compared to the original version of the virus. It was on the 7th floor.

The researchers found in the shared study results that the effect of Omicron varied greatly between samples, where it was in the lab rather than live virus. that they use an artificially produced version of Omicron they stated. It has been stated that Omicron is definitely worse than Delta, but still not as extreme as expected.

Previous studies for the Delta variant had shown that the level of reduction in antibody was 2-3-fold, and in Beta 7-8-fold. It is stated that the results of the new studies are not conclusive, yet there is a that there are preliminary results and they are waiting for approval Let’s remind again.
