More than half of all adults in the United States have received at least a first dose of coronavirus vaccine as of Sunday.
Since the US started its vaccine drive four months ago, 50.4 per cent of adults – some 130 million people – have had at least one jab, according to figures from the country’s Centers for Disease Control and Prevention (CDC).
Almost one-third of adults have been fully vaccinated.
Among the higher-risk group of those aged 65 and older, 81 per cent have had a first dose, and around two-thirds are fully vaccinated.
An average of more than 3 million shots are currently being administered daily, according to the White House.
In total, almost 210 million doses have been administered in the country, which has a population of 330 million.
A nurse received the country’s first jab in New York on December 14, 2020.
The US is largely using Moderna and Pfizer vaccines, and recently suspended shots from Johnson & Johnson after six US cases of cerebral venous thrombosis were recorded.
The Johnson & Johnson vaccine requires only one injection to be fully effective, while two doses are required for the other vaccines.
