About one-fifth of people in the United States – about 66 million people – have been fully vaccinated against COVID-19, data from the US Centres for Disease Control and Prevention shows.
About 112 million people – about one-third of the population – have received at least one dose since the vaccine drive started in mid-December.
In total, almost 175 million jabs have been administered.
The US has a population of about 330 million.
It’s using the Moderna and Pfizer vaccines, which require two doses, as well as the Johnson & Johnson jab, which becomes fully effective after just one dose.
The Pfizer shot is authorised for use in people over the age of 16, while the others can be used only on people over 18 years old.
US President Joe Biden has promised to provide enough shots for the country’s entire adult population by the end of May.
