More than 300 million doses of the COVID-19 vaccine have now been given out across the United States, according to data from the Centers for Disease Control and Prevention.
In all, more than 170 million people have received a first dose of the vaccine, or about 51.5% of the U.S. population, the CDC reports. Another 138 million are fully vaccinated, either through two doses of the Moderna or Pfizer vaccines, or a single dose of Johnson & Johnson's shot.
This new landmark achievement comes less than a week after the Biden administration announced it would be sending an initial allotment of 25 million doses of surplus vaccine to the United Nations-backed COVAX program in aid of the global vaccination effort.
