WASHINGTON (AP) — A government report suggests the U.S. is falling short of the White House goal of increasing COVID-19 vaccine coverage in poor, struggling communities.

The Centers for Disease Control and Prevention’s report, released Wednesday, indicates 31 states are failing to meet the goal.

In contrast, Arizona and Montana are achieving equity in vaccine coverage, directing vaccines to counties with more economic and social disadvantages. Three other states – Alaska, Minnesota and West Virginia – are doing fairly well by that measure, the report said.

The CDC looked county-by-county at the proportion of people getting at least one dose of vaccine. Coverage was lower in counties with more economic and social disadvantages as measured by the CDC’s social vulnerability index. That’s a measure combining factors such as poverty, education, crowded housing and racial and ethnic minority population.

The CDC analyzed vaccine coverage through March 1 and included data representing 49.2 million people who had at least one dose. Hawaii did not systematically report county of residence, so the state was omitted from the analysis.

The national average of vaccine coverage 15.1%, the report said. In better-off counties, coverage was 15.8%. In worse-off counties, coverage was 13.9%.

Meanwhile, White House officials announced Wednesday that the Biden administration is working to make a leading COVID-19 therapy available to even more Americans.

Dr. Marcela Nunez-Smith, the White House COVID-19 equity task force chair, said that the administration is spending $150 million to broaden access to monoclonal antibodies. When administered early in the course of infection, the treatments can dramatically reduce serious illness or hospitalization.

Nunez-Smith said the treatments are available in 5,000 locations across the country already, with more locations — particularly in hard-hit communities to follow in the coming weeks.

The administration is also increasing its outreach to caregivers to encourage them to utilize the therapies to prevent deaths and hospitalizations.
