SAINT LOUIS – Annual boosters of the COVID-19 vaccine might not be necessary, according to a new study.
A new study indicates some COVID-19 vaccines could offer long-term protection, longer than the protection offered by flu vaccines, which need boosting every year.
Researchers at Washington University in Saint Louis found people who got two doses of Pfizer’s Coronavirus vaccine produced a type of immune cell called a ‘b-cell’ which should, in theory, keep pumping out protection for years, making follow-up COVID vaccines unnecessary for the time being.
Experts are now looking at people who recovered from an infection and then got vaccinated.
It’s possible that group could have an even stronger and broader immune response.
The study was published Monday in the medical journal: Nature.
