U.S. health officials raised an 11-day drop on COVID-19 vaccinations with Johnson & Johnson’s single-dose shot Friday, after scientific advisors chose its benefits outweigh an infrequent possibility of blood clots. The us government found 1-5 vaccine recipients who developed an extremely strange form of blood-clot out of almost 8 million people awarded the J&J shot. All of the women, many under age 50. Three expired seven and seven remain hospitalized.
