See How Vaccinations Are Going in Your County and State

The Centers for Disease Control and Prevention said on Wednesday about 208 million people have received at least one dose of a Covid-19 vaccine, including about 177.1 million people who have been fully vaccinated by Johnson & Johnson’s single-dose vaccine or the two-dose series made by Pfizer-BioNTech and Moderna.

The C.D.C. also reported that about 1.5 million fully vaccinated people have received an additional vaccine dose since Aug. 13, the day after the F.D.A. opened up eligibility for third shots for some people with weakened immune systems. This figure does not include an estimated 1.2 million people in the U.S. who may have already received unauthorized additional doses prior to mid-August, according to the C.D.C.

About 75.2 percent of adults have received at least one shot. President Biden set a goal on May 4 of reaching 70 percent of adults by July 4, but it took almost a month extra to reach that national target. Here’s how states are progressing toward that 70 percent benchmark.

How Quickly Are Shots Going in Arms?
Providers are administering about 811,000 doses per day on average, about a 76 percent decrease from the peak of 3.38 million reported on April 13.

Figures show the date shots were reported, rather than the date shots were given and include first and second doses of Pfizer-BioNTech and Moderna, and single doses of Johnson & Johnson.

In December, federal regulators gave emergency use authorization to two-dose vaccines developed by Pfizer-BioNTech and Moderna. Regulators authorized Johnson & Johnson’s one-dose vaccine in February, but recommended a pause in its use on April 13 because of reports of blood clots in a small number of patients. All 50 states paused or recommended that providers pause those vaccinations. The government ended the Johnson & Johnson pause on April 23, clearing the way for states to resume vaccinations.

Johnson & Johnson doses that were already administered or distributed continued to appear in the federal vaccination data during the halt in use.

On Aug. 12, regulators gave emergency use authorization for people with weakened immune systems to get a third dose of the Pfizer and Moderna vaccines. On Aug. 23, the federal government approved the Pfizer-BioNTech vaccine for those 16 and older, the first full approval of a Covid-19 vaccine in the country. Emergency use authorization of the vaccine continues for those ages 12 to 15 and third doses for those with weakened immune systems.

Some experts have estimated that 90 percent or more of the total population — adults and children — would need to be fully vaccinated for the country to reach a possibly elusive threshold of protection against the coronavirus known as herd immunity, now that the outbreak is driven by the highly contagious Delta variant.

A number of factors will determine if and when this threshold is met, including the pace at which newly vaccinated people join those who are immune after past infections. But the presence of more transmissible virus variants could complicate that progress. And children, who aren’t yet eligible, may be key to reaching herd immunity, experts say.

The projection below only shows the share of the total population with at least one shot based on the current rate of newly vaccinated people, but it provides a rough indication of when the virus’s spread could begin to stall.
