The New COVID Booster Shot Could Save Your Life; Get One Now, FDA Expert Says

FDA Chief Medical Officer Hilary Marston explains the importance of getting a booster shot, considers why so few people have gotten them and answers other questions
According to an announcement from Pfizer-BioNTech on Friday, the revised booster dose produces a greater immune response against the omicron subvariants BA.4 and BA.5 than the original Covid vaccination.
The outcomes are based on blood samples given from adults one month following single doses of the revised booster shot or initial vaccine versions.
The original coronavirus strain was the focus of Pfizer’s vaccine formulation, which was introduced to older adults in December 2020. The new booster shot is made to simultaneously attack the original viral strain, BA.4, and BA.5.

As we’ve learned over the last year, COVID-19 variants are to be expected.

According to Pfizer, persons 55 years of age and older who received the updated vaccine had neutralizing antibodies against BA.4 and BA.5 that were around four times greater than those of the same age who received the original vaccine.
The findings, which Pfizer disclosed in a news release, have not been submitted to or evaluated by outside scientists for publication in a medical journal.
