UK Prime Minister, Boris Johnson, is pledging to donate most of the country’s surplus vaccine supply to poorer countries.

Speaking at a virtual G7 meeting today, Johnson urged rich countries to support a 100-day target for the development of new vaccines for future emerging diseases.

The UK has ordered more than 400 million doses of various vaccines, that will result in many being left over once all adults are vaccinated.

But anti-poverty campaigners say the country isn’t doing enough.

Decisions regarding the surplus distribution will be made later this year, with ministers taking into account the supply chain and whether booster shots will be needed.
