Pfizer Vaccine Has 5 Times Fewer Antibodies Against Delta Variants Of Corona: Lancet
People fully vaccinated with the Pfizer-BioNTech Vaccine were five times less likely to have neutralizing antibodies against the delta variant, first identified in India, compared to the original strain.
London:
According to research published in The Lancet journal, people fully vaccinated with the Pfizer-BioNTech Vaccine showed antibodies against the first identified delta variant in India compared to the original strain. The deactivation level is likely to be five times lower. The study also shows that the levels of these antibodies that are able to recognize and fight the virus decrease with age and that levels decline over time, in support of plans to give booster doses to vulnerable people. provides evidence.
This supports current plans to reduce the dose gap between vaccines in the UK as they found that after just one dose of the Pfizer-BioNTech vaccine, people were less likely to develop antibody levels against the B.1.617.2 variant. The probability is the same as observed against the previously dominant B.1.1.7 (alpha) variant, first detected in Kent.
The team, led by researchers from the Francis Crick Institute in the UK, found that antibody levels alone do not predict the effectiveness of the vaccine, and that a prospective population study is also needed. He added that low neutralizing antibody levels may still be linked to protection from COVID-19.
Let us inform that the delta form of corona first appeared in India or B1.617.2 has now become a cause of concern in Britain and due to its outbreak, the number of patients in hospitals is expected to increase. UK health officials said this.
According to Public Health England (PHE), which monitors all forms of Kovid in the country, cases of infection from the delta form of the virus increased by 5,472 in a week and the total number of cases on Thursday rose to 12,431. After looking at the latest data, experts said that Delta seems to be more effective than Alpha in terms of losses.
Dr Jenny Harris, Chief Executive Officer of Britain’s Health Protection Agency, said, “Given the nature of the virus that has now spread across the UK, it is important that we all take as many precautions as possible.” Work from home, keep hands, face and surroundings clean at all times. If not vaccinated, then get vaccinated and also take another dose of vaccine. This will save lives.”
