From November 8, the Biden administration will allow all international visitors to enter the United States if they have received any World Health Organization-approved vaccine, including the relatively untested Chinese-made Sinovac and Sinopharm jabs.
The US president, Joe Biden, signed a presidential proclamation on Monday outlining the country's new international travel rules, which will replace the patchwork of blanket bans in place since the outbreak began.
The proclamation was accompanied by a set of detailed instructions for airlines, which will be held accountable for enforcing the new vaccine mandates.
The rules, which go into effect in two weeks, will allow anyone who has been immunised with one of the seven WHO-approved vaccines to enter the US by land or air.
They include the Sinovac and Sinopharm vaccines, which were developed in China despite a lack of data on their efficacy against the coronavirus's Delta variant.
Travelers will also be permitted to receive "mix and match" vaccinations, which will allow them to receive one dose from one vaccine manufacturer and another from another.
