The World Health Organization says the Covid pandemic will “go on for a year longer than it needs to” because poorer countries are not getting the vaccines they need. Dr Bruce Aylward, senior leader at the WHO, said it meant the Covid crisis could “easily drag on deep into 2022”. Less than 5% of Africa’s population have been vaccinated, compared to 40% on most other continents. The UK has delivered more than 10 million vaccines to countries in need. It has pledged a total of 100 million.
