May 25 (UPI) -- A new vaccination milestone is expected to be reached by the end of Tuesday, with half of all adults in the United States fully vaccinated against COVID-19.
The Centers for Disease Control and Prevention says almost 130 million U.S. adults are now fully vaccinated -- or about 49.8% of the adult population.
Biden pledged to make vaccines more accessible by directing tens of thousands of pharmacies to take walk-in appointments and redirecting resources to support other community efforts.
CDC data shows that at least 25 states and Washington, D.C., have fully vaccinated at least half of their adult residents.
Earlier Tuesday, Moderna announced that its vaccine is safe and effective in children between the ages of 12 and 17. If approved by regulators next month, it would be the second coronavirus vaccine available in the United States to children.
