About 90 countries will share the doses without any counterclaims, according to the president.

- It is about our responsibility and our humanitarian duty to save as many lives as possible, Biden said.

At the meeting with Boris Johnson, Biden, according to Reuters, has warned the British from disturbing the fragile peace in Northern Ireland with trade barriers linked to Brexit.
