Wealthy countries seeking more Covid-19 vaccines are undermining the Covax initiative to inoculate the world’s poorest people against Covid-19, the head of the World Health Organisation said. Dr Tedros Adhanom Ghebreyesus said the coronavirus could not be defeated unless it was tackled globally. Billions of dollars have been pledged to Covax to ensure equitable and affordable access to vaccines. Dr Tedros thanked G7 countries for recent “significant” donations, which now total $7.5 billion. “Even if you have the money, if you cannot use the money to buy vaccines, having the money doesn’t mean anything,” Dr Tedros said during a press conference with German President Frank-Walter Steinmeier. G7 member Germany pledged to donate €1.5bn ($1.82bn) last Friday to Covax. But rich countries have also bought up billions of vaccine doses while poorer nations struggle to obtain them. Dr Tedros said rich countries must ensure their vaccine orders did not undermine the programme. “But I don’t think they’re asking that question, and that’s why one thing that I would ask the high-income countries is: before they ask the manufacturers or the private sector for additional vaccines they should make sure whether their request affects the Covax deal or not.” Dr Tedros underlined the importance of accelerating vaccine supply, “because with increased production, the pie is increased, then there is a better volume to share. Otherwise, with shortages, sharing is difficult,” he said. “And that’s exactly what’s happening now.”
