The Pfizer-BioNtech COVID-19 vaccine may require a third dose to work more effectively against the coronavirus (Covid-19). The third Covid-19 shot is also expected to provide better protection against the beta variant. 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 will try to get approval in view of the interim trial data, which showed that the third dose can increase antibody levels by five to ten times compared to the first two doses.
In fact, this third Covid-19 dose is expected to provide better protection against the beta variant of the corona. The beta variant was first found in South Africa. This variant is the most powerful ever. It is even more effective than the Delta variant.
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.
