The head of the World Health Organization, marking a year since the first cases of the novel coronavirus were reported by China, urged countries on Wednesday to ensure that vaccines are made available to people at risk everywhere, not just in rich nations.
Tedros Adhanom Ghebreyesus, WHO director-general, appealed for $4 billion to buy COVID-19 vaccines for distribution in lower and middle-income countries through the COVAX vaccine facility.
