See How Vaccinations Are Going in Your County and State

The Centers for Disease Control and Prevention said on Friday about 214.6 million people have received at least one dose of a Covid-19 vaccine, including about 184.9 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 4.4 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 also includes people who have gotten a booster dose, which the F.D.A. authorized on Sept. 22 for Pfizer-BioNTech recipients over 65 or at high risk of severe Covid-19.

The number above 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.

How Quickly Are Shots Going in Arms?

Providers are administering about 741,000 doses per day on average, including first, second and additional doses, about a 78 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.

When Might Nearly Everyone Be Vaccinated?

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.

But the pace of vaccinations varies across the country. Many states in the South and West, for example, have vaccinated a smaller share of their population with a first or single dose than in other regions.

There are many reasons eligible people are not vaccinated. Surveys have indicated that some people are adamant in their refusal of the coronavirus vaccines, while others are open to getting a shot but have been putting it off or want to wait and see before making a decision.

The first group, surveys have shown, tends to be disproportionately white, rural, evangelical Christian and politically conservative. The second group tends to be a more diverse and urban group, including many younger people, Black and Latino Americans, and Democrats.

In April, The New York Times analyzed vaccine records and voter records in every county in the United States and found that both willingness to receive a coronavirus vaccine and actual vaccination rates were lower, on average, in counties where a majority of residents voted to re-elect former President Donald J. Trump in 2020.

Are The Most Vulnerable Counties Being Vaccinated?

Speed isn’t the only priority for the country’s vaccination campaign. The Biden administration has also committed to distributing shots equitably to the communities most affected by the pandemic.

Yet many months into the rollout, the most socially vulnerable counties in the U.S. have a lower vaccination rate on average than the nation’s least vulnerable. The majority of the most disadvantaged counties with the fewest fully vaccinated people are in the South, while the most vaccinated, least vulnerable counties are in the Midwest and Northeast.

Counties are ranked according to the Social Vulnerability Index, a C.D.C. indicator used in public health crises that is based on socioeconomic status, housing, transportation, race, ethnicity and language. Each county’s vaccination rate is its share of all residents that have been fully vaccinated, a figure that does not reflect those who have only received one dose of a two-shot vaccine.

How Is Each State Doing?

Some jurisdictions have been more efficient than others at administering their doses from the federal government.

The table below includes states, territories, federal agencies and three countries with special agreements with the United States: Palau, Micronesia and the Marshall Islands.

People that have received the single-shot Johnson & Johnson vaccine are included in counts for those with “at least one dose” and those “fully vaccinated.”

There are many reasons for variation among the states and territories, including demand for the vaccine, lags in data reporting and other logistical challenges. State progress varies by age group as well.

Who Is Eligible for a Vaccine?

The United States has cleared an important milestone in its vaccine rollout: All people 12 and older are now eligible for the coronavirus vaccine in every state, according to a Times survey.

Universal eligibility follows months where states relied on complicated phase-based plans that prioritized certain vulnerable individuals — like older Americans, critical workers and those with certain medical conditions. Often, county plans differed from state plans.

Health care workers and residents of long-term care facilities have been eligible for vaccination in every state since the early part of 2021, and people 65 and older have been eligible for several months in every state.

The C.D.C. on May 12 expanded the emergency use authorization for the Pfizer vaccine to permit use in children 12 and older, allowing young adolescents to potentially start getting vaccinated before school starts in the fall of 2021. It is unclear when children 11 and younger will be eligible for a vaccine. Pfizer and Moderna have expanded the size of their clinical trials for children ages 5 to 11 — a precautionary measure designed to detect rare side effects including heart inflammation problems that turned up in vaccinated people younger than 30.

About the Data

Data on vaccines delivered and administered comes from the Centers for Disease Control and Prevention, which updates data daily and reports detailed footnotes here.

The C.D.C. began reporting county-level vaccinations on March 26. This data is not available for all states, and is incomplete in others, artificially lowering the published vaccination rates for some counties.

Figures include vaccines developed by Pfizer-BioNTech, Moderna and Johnson & Johnson. People receiving the Johnson & Johnson single-shot vaccine are counted as those with “at least one dose” and those “fully vaccinated.”

The federal data may differ from that reported by states and territories, which may post on different schedules. Providers have 72 hours to report doses administered and it can take additional time for jurisdictions and the C.D.C. to receive this information.

The C.D.C. typically reports data as of 6 a.m. each day. On March 13, the C.D.C. reported about 4.6 million new doses administered, including about 1.6 million doses that were reported after the 6 a.m. cutoff, resulting in a visible spike.

On May 16, the C.D.C. reported an erroneous increase in New Hampshire vaccinations, which artificially raised the total doses administered in the U.S. The data has since been updated, with a new U.S. figure for May 16 that is about 620,000 doses lower.

On June 14, the C.D.C. included in its counts about 340,000 additional doses administered from vaccination records that had been received but not fully processed.

The C.D.C. notes that total doses administered are based on the location where the vaccine was given, and that in limited cases, people might get a vaccine outside of their place of residency. As of Feb. 23, the C.D.C. reports the number of people receiving one or more doses based on where individuals reside.

On Feb. 19, the C.D.C. began including shots given by the federal agencies in each state’s count. Doses delivered to federal agencies were added to state totals on Feb. 20. Some states, including Alaska, North Dakota and Utah, are supposed to receive supplements for tribal governments that have elected to receive their vaccines through the state, rather than through the federal Indian Health Service.

In addition to delivering vaccines to states, territories and some federal agencies, the C.D.C. also distributes doses to three small countries that have special agreements with the U.S. government: Palau, Micronesia and the Marshall Islands.

The C.D.C. also reports state-level data on the number of shots administered to people in nursing homes and long-term-care centers.
