In view of the fear of the third wave of corona and the changing nature of the virus, the American vaccine manufacturer is preparing to give the third dose. American pharmaceutical company Pfizer-BioNtech is trying to get approval for the third dose. The company claims that a third dose may be needed to beat Corona. The company announced on Thursday that they would seek regulatory approval for their Covid-19 vaccine. The company will seek approval in view of data from the interim trial, which showed that the third dose can increase antibody levels by five to ten times as compared to the first two doses.
Actually, this third Covid-19 dose is expected to provide better protection against the beta variant of Corona. The beta variant was first detected in South Africa. This variant is the most powerful ever. It is even more effective than the Delta variant.
Actually, the Pfizer vaccine is less effective in protecting against the delta variant of the corona. A study revealed that this vaccine is not very effective in producing antibodies in the body of people who have not had corona virus before and if they are infected with the delta variant of corona. A study published in ‘Journal Nature’ claimed that the effect of the Pfizer vaccine on the delta variant of Covid-19 was not shown much. According to the report, Pfizer is up to 64 percent effective in blocking the effects of the Delta variant. Earlier this vaccine was up to 94 percent effective in other variants of Corona. In such a situation, Pfizer is seeking permission to give the third dose.
