The decision follows the emergence of a highly infectious new coronavirus variant in Britain, which has prompted many countries to shut their borders to travellers from there.

Pfizer and BioNTech, by contrast, presented data on 36,523 people to show that its vaccine has an efficacy rate of 95%.

"This additional testing requirement will fortify our protection of the American public to improve their health and safety and ensure responsible worldwide travel", the CDC said in a statement.
