The World Health Organization is calling for a moratorium on Covid-19 vaccine booster shots until at least the end of September, WHO director-general Tedros Adhanom Ghebreyesus said on Wednesday.
"Even while hundreds of millions of people are still waiting for their first dose, some rich countries are moving towards booster doses," Tedros said. "So far more than 4 billion vaccine doses have been administered globally. More than 80% have gone to high and upper middle income countries, even though they account for less than half of the world's population."
Germany, the UK, and Israel have all announced plans to provide booster shots for certain vulnerable populations.
