During a study in Britain, it has been revealed that the vaccine is effective against the delta variant of the corona virus. In the second wave of the corona epidemic in India, the situation worsened due to the delta variant and the delta variant overtook the alpha variant in terms of infectiousness in Britain. A new scientific analysis published by Public Health England has found that two doses of the corona vaccine are effective in preventing hospitalization due to B.1.617.2 (Delta Variant). Apart from this, it has been revealed in the study that those who have been vaccinated, have not died due to this variant. This analysis is yet to be peer reviewed.
The study found Pfizer-BioNtech’s mRNA vaccine to be 96 percent effective and Oxford-AstraZeneca’s vaccine 96 percent effective in preventing hospitalization after two doses. The Delta variant was first found in India.
analysis done like this
Researchers from the London School of Hygiene and Tropical Medicine and London’s Guys and St Thomas NHS Foundation Trust compared all symptomatic corona cases between 12 April and 4 June with the Emergency Care Dataset (ECDS). In this data set, records of patients admitted to the Emergency Department in England are kept. In the analysis, out of 14,019 cases of the delta variant, only 166 were found hospitalized.
The analysis found that the first dose of the Pfizer vaccine was 64 percent and the second dose 96 percent effective in preventing hospitalization due to the delta variant, similar to the alpha variant. At the same time, the first dose of Oxford-AstraZeneca vaccine is 71 percent and the second dose is 92 percent effective. The Coveshield of the Oxford-AstraZeneca Vaccine is being installed in India.
First death confirmed in India after COVID-19 vaccination, but experts said, the benefits outweigh the risks
Similar claim in Lassant’s study
The delta variant of the corona virus doubles the risk of hospitalization compared to the alpha variant. But the vaccines of Pfizer and AstraZeneca provide good protection against the strain. This has been revealed in a study published in The Lancet Journal. This analysis was done on 19,543 confirmed SARS-CoV-2 infections in the period 1 April to 6 June 2020, of which 377 were hospitalized in Scotland for COVID-19. The delta variant of the corona virus was found in about 7,723 cases and 134 corona patients admitted to the hospital. The study found that the Pfizer vaccine provides 92 percent protection against the alpha variant and 79 percent against the delta strain. This protection is available two weeks after the second dose.
