More countries are starting to require travellers to be able to prove they have received the booster Covid-19 jab. But the government has yet to say when this will be included on the NHS app, despite prime minister Boris Johnson insisting that it will happen.

Willie Walsh, director general of airlines association Iata, told the committee hearing that many countries currently required vaccine proof for travellers aged over 12.
