The United States is averaging fewer than 1 million shots per day, a decline of more than two-thirds from the peak of 3.4 million in April, according to The Washington Post’s seven-day analysis, even though all adults and children over age 12 are now eligible... The slowdown is national — with every state down at least two-thirds from its peak — and particularly felt across the South and Midwest. Twelve states, including Utah, Oklahoma, Montana, the Dakotas and West Virginia, have seen vaccinations fall below 15 daily shots per 10,000 residents; Alabama had just four people per 10,000 residents get vaccinated last week... The steep decline began in mid-April, coinciding with federal officials’ temporary suspension of the Johnson & Johnson vaccine while they probed rare blood-clotting reactions. That slowdown has continued, with only 2.4 million adults getting their first shot last week. Officials must get a first dose to 4.2 million adults per week to meet Biden’s goal of ensuring that 70 percent of adults are at least partially vaccinated by Independence Day. Complicating the push: Health officials have already reached the “low-hanging fruit — those people who absolutely want to get vaccinated without you telling them anything,” Anthony S. Fauci, the government’s top infectious-diseases expert, said on a White House-organized call with community leaders on Friday. “You’re left with a group that you may need … trusted messengers who go out there and explain to them why it’s critical for themselves, for their family.”
