WASHINGTON — Half of all adults in the U.S. have received at least one COVID-19 shot, the government announced Sunday, marking another milestone in the nation’s largest-ever vaccination campaign but leaving more work to do to convince skeptical Americans to roll up their sleeves.

What You Need To Know

  • Half of all adults in the U.S. have received at least one COVID-19 shot, according to CDC data

  • This marks another milestone in the nation’s largest-ever vaccination campaign 

  • The U.S. cleared the 50% mark for adults just a day after the reported global death toll from the coronavirus topped a staggering 3 million

  • Almost 130 million people 18 or older have received at least one dose of a vaccine

Almost 130 million people 18 or older have received at least one dose of a vaccine, or 50.4% of the total adult population, the Centers for Disease Control and Prevention reported. Almost 84 million adults, or about 32.5% of the population, have been fully vaccinated.

The U.S. cleared the 50% mark for adults just a day after the reported global death toll from the coronavirus topped a staggering 3 million, according to totals compiled by Johns Hopkins University, though the actual number is believed to be significantly higher.

In other developments, the nation’s top infectious diseases expert indicated Sunday that the government will likely move to resume use of Johnson & Johnson’s COVID-19 vaccine this week, possibly with restrictions or broader warnings after reports of some very rare blood clot cases.

Dr. Anthony Fauci, in a series of news show interviews, said he expects a decision when advisers to the Centers for Disease Control and Prevention meet Friday to discuss the pause in J&J’s single-dose vaccine.
