» U.S. hits vaccine milestone,

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.

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.

The country’s vaccination rate, at 61.6 doses administered per 100 people, currently falls behind Israel, which leads among countries with at least 5 million people with a rate of 119.2. The U.S. also trails the United Arab Emirates, Chile and the United Kingdom, which is vaccinating at a rate of 62 doses per 100 people, according to Our World in Data, an online research site.

The states with the highest vaccination rates have a history of voting Democratic and supporting President Joe Biden in the 2020 election: New Hampshire at the top, with 71.1%, followed by New Mexico, Connecticut, Massachusetts and Maine, CDC data show.

The bottom four states for rates of adults getting at least one shot are Louisiana, Alabama, Mississippi and Tennessee — Southern states that lean Republican and voted for Donald Trump.

Vaccination rates do not always align with how states vote. But polling from The Associated PRESS-NORC Center for Public Affairs Research has shown trends that link political leanings and attitudes about the vaccines and other pandemic-related issues.

A poll conducted in late March found that 36% of Republicans said they will probably or definitely not get vaccinated, compared with 12% of Democrats. Similarly, a third of rural Americans said they were leaning against getting shots, while fewer than a fourth of people living in cities and suburbs shared that hesitancy.

In January, 67% of adult Americans were willing to get vaccinated or had already received at least one shot. The figure has climbed to 75%, according to the latest AP-NORC poll.

Nationwide, 24% of Black Americans and 22% of Hispanic Americans say they will probably or definitely not get vaccinated, down from 41% and 34% in January, respectively. Among white Americans, 26% now say they will not get vaccinated. In January, that number was 31%.
