WASHINGTON (AP) — The Food and Drug Administration has approved a new kind of flu vaccine for older people, the first made with the same mRNA technology that was key to ending the COVID-19 pandemic, manufacturer Moderna said. The shot, named mFlusiva, is intended for adults age 50 or older. While there already are multiple flu vaccine options in the U.S., including three specifically recommended for people age 65 or older, tens of thousands of Americans die from influenza every year and older adults are among the most vulnerable. Flu vaccines must be updated annually to best match circulating strains of the virus. The FDA action comes after a highly unusual public dispute over mFlusiva earlier this year.
