The World Health Organisation approved the AstraZeneca COVID-19 vaccine for emergency use last night in a move that will facilitate the vaccination of millions of people in developing nations. While wealthy countries have been able to secure vaccines on their own, much of the developing world relies on the W-H-O for its jabs. The AstraZeneca vaccine is cheaper and easier to distribute than the already-approved Pfizer vaccine, making its rollout less of a burden for overwhelmed health systems around the world.
