The U.S. reached a milestone in its vaccination efforts on Wednesday, with new data showing that close to 25% of adults in the country have been fully vaccinated, NBC News reports.
The data from the Centers for Disease Control and Prevention also show that 40% of adults and 75% of seniors have received at least one dose.
The country’s COVID-19 vaccination efforts began in December after the emergency authorization of a vaccine by the U.S. drugmaker Pfizer and the German firm BioNTech. That effort was greatly accelerated with the addition of the Moderna and Johnson & Johnson vaccines.
States such as Illinois and California have tied their reopening plans to the success of vaccination efforts, which determine when it’s safe to resume large gatherings.
Certain states, such as New Mexico, South Dakota and Alaska, have surpassed the national average and fully vaccinated more than 30 percent of their adult populations, according to CDC data.
