Pfizer says federal regulators will decide if booster shots are needed and in which populations a third dose is recommended.

The Delta mutant is currently the predominant strain in the United States, and the recent increase in coronavirus cases is due to its predominance in the United States.
Despite the promising data released by Pfizer, it is unclear whether a third dose is needed, as current vaccines have been shown to be effective in preventing serious illness.
According to a study published last week, two doses of the Pfizer or AstraZeneca vaccine are about as effective against the delta mutant as well as the previously predominant alpha mutant. Reuters report.. The study found that two doses of Pfizer shots were 88% more effective in preventing symptomatic disease with delta variants than 93.7% against alpha strains.
