“The Food and Drug Administration (FDA) plans to allow Americans to use a different COVID-19 vaccine as a booster than the one they received first,” it said.
The regulator will most likely not recommend mixing vaccines and emphasizing the desirability of using the same drug as a booster. However, vaccine suppliers will obviously be allowed to suggest a different brand at their own discretion, the post said.
This decision may also be prompted by the results of studies presented last Friday. According to doctors, people who received a single dose of Johnson & Johnson, after the second same vaccination, demonstrated a fourfold increase in the number of antibodies. However, those who received a booster from Moderna after the first J&J vaccine had a 76-fold increase in antibody levels.
