The White House announced Friday that Dr. Anthony Fauci, medical advisor to President Joe Biden, said he expects Americans who received the one-dose J&J vaccine against COVID-19 also will be recommended for a booster shot. Federal health officials have said it’s likely that those who received the Johnson & Johnson (J&J) vaccine will need a booster as well. They are still analyzing the data on that vaccine. More guidance for Johnson & Johnson recipients is expected in the coming weeks.
