U.S. will allow to get a second Covid jab of a different vaccine.

The Food and Drug Administration (FDA) is planning to allow Americans to receive a different Covid-19 vaccine as a booster than the one they initially received. The New York Times reports this, citing sources.

"The government would not recommend one shot over another, and it might note that using the same vaccine as a booster when possible is preferable", the report said.

The approach was foreshadowed on Friday, when FDA researchers presented the findings of a federally funded “mix and match” study to an expert committee that advises the Food and Drug Administration. The study found that recipients of Johnson & Johnson’s single-dose shot who received a Moderna booster saw their antibody levels rise 76-fold in 15 days, compared with only a fourfold increase after an extra dose of Johnson & Johnson.
