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.

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 just a day after the reported global death toll from the coronavirus topped 3 million, according to totals compiled by Johns Hopkins University, though the actual number is believed to be significantly higher.

Within the U.S., New Hampshire, Maine, Connecticut, Massachusetts and New Mexico report the highest percentage of population who have received at least one dose, according to NPR’s vaccination tracker.

Most of the states with the highest vaccination rates have historically voted Democratic in presidential elections, with the exception of South Dakota.

On the flip side, many of the states reporting the lowest rates of people receiving at least one dose of vaccine are traditionally Republican voting.
