The NHS is launching a 'vaccine passport' on its app for international travel

• The UK's National Health Service is adding a "vaccine passport" to its app, the government said.
• The new service is designed to clear travelers for international trips.
• The feature is set to launch on Monday.

The UK's National Health Service app will be available on Monday to use as a COVID-19 "vaccine passport" for people who are fully vaccinated and want to travel internationally, the government told The Times and the BBC.

Downing Street said the app feature would be ready on Monday, when the UK's ban on international travel is lifted.

People without smartphones will be able to get paper documents to confirm their vaccination status through calling 119, the government said.

People who are not fully vaccinated will still have to follow testing regulations and COVID-19 rules for the countries they're traveling to, the government says on its website.

However, the website also says that people who are fully vaccinated might still need to isolate or show proof of a negative COVID-19 test to get into another country.

"There are not many countries that currently accept proof of vaccination," it said. "So for the time being most people will still need to follow other rules when travelling abroad - like getting a negative pre-departure test."
