After the new variants of the corona virus were found, there was concern about the effect of the vaccine on them. However, according to a study published in the New England Journal of Medicine, Pfizer and BioNTech’s Corona virus vaccine has been found to be effective against variants spreading in Brazil. The study has found that the vaccine has shown efficacy against viruses containing the spike protein of the infectious P.1 variant. This is similar to the effect on the chronic corona virus, which is less infectious than it is.

Preparing to meet the new challenge

Despite the comforting news, the company is planning to test three booster doses instead of two. Apart from this, work is also being done on such version which is especially effective against the new variant so that the immune response can be understood better. At the same time, Moderna has already sent its booster vaccine to the National Institutes of Health for clinical trials. Both companies say that booster doses will be ready at the end of the year 2021 or early 2022.

Health experts are worried that the new wave of corona virus may not start due to variants. 3000 new cases of UK B117 strains have been reported in the US. 81 people are infected with the B1351 variant of South Africa. At the same time, 15 people are infected with the Brazilian variant. Scientists have feared that B117 is going to spread rapidly this month. The effect of the vaccines has been satisfactory against the British variant, but there was concern about the Brazilian and South African variants.
