Booster May Be Necessary For Pfizer, Moderna Vaccines

The CEOs of Moderna and Pfizer said they might require a booster dose as soon as September for those among the earliest vaccinated. Depending on the research results on the longevity of the vaccines, you might need a booster shot between eight to 12 months after the initial two-dose vaccine series. Pfizer says the decision is dependent upon the CDC and the FDA approving booster shots.
