Vaccinating poor countries should be a bigger global priority than booster shots for rich countries
The UK is enjoying real success with its Covid-19 vaccine coverage. Around 85% of adults (44.8 million people) have received one vaccine dose and 63% (33 million people) both doses, with around 160,000 doses a day still being administered.

Vaccination with two doses helps prevent infection, and in those that do still get infected, lessens the impact of the virus by reducing disease severity, transmission of infection, and death.
