Johnson & Johnson seeks emergency authorization from FDA for coronavirus booster shot

Johnson & Johnson asked the Food and Drug Administration on Tuesday to grant emergency use authorization for a booster dose of its single-shot coronavirus vaccine. The action is part of an effort by Biden administration officials to provide increased protection against covid-19, the disease caused by the coronavirus, which has claimed more than 700,000 lives in the United States. Johnson & Johnson “is asking the FDA to look at our data and agree with us that we have enough data to support a boost” for people 18 and older, said Mathai Mammen, global head of research and development for the Janssen Pharmaceuticals division of Johnson & Johnson.
