The omicron variant pushed new daily cases of COVID-19 to all-time highs in the United States and underscored the urgency of the national vaccination effort. So far, an estimated 220,287,778 Americans have been fully vaccinated, or 67.3% of the population.

Some states are proving more effective than others in getting their residents vaccinated. Depending on the state, the share of the population that has been fully vaccinated ranges from as low as 51.0% all the way up to 82.9%.

Due in large part to vaccine hesitancy and resistance, millions of doses are currently sitting idle under the purview of state governments, yet to be administered. As of May 10, only about 79.1% of the 733,497,200 doses of the vaccine that have been distributed to the 50 states and Washington D.C. have been administered. In one state, only 64.6% of delivered doses have gone into the arms of residents.

Meanwhile, the virus continues to spread. In total, there have been 24,777 known infections for every 100,000 people nationwide.
