More than 30 percent of the adult population, or about 78.5 million people, is fully vaccinated against COVID-19 in the country, according to new data from the US Centers for Disease Control and Prevention.
The CDC says 48 percent of adults and 80 percent of at-risk seniors have received at least one dose of the vaccine.
Sixty-four percent of older people are fully vaccinated.
The agency also reported 5800 cases of infection among vaccinated people.
“All available vaccines have proven effective in preventing severe illness, hospitalization and death,” the agency said in a statement.
At the same time, the CDC expects that there will be thousands more cases of infection among vaccinated people.
