WHO Chief Warns of 'Vaccine Nationalism' VOA News The World Health Organization's (WHO) director-general Tuesday issued another warning against "vaccine nationalism," -- countries putting their own interests ahead of others in trying to secure supplies of a possible vaccine. At the agency's regular briefing in Geneva, WHO Director-General Tedros Adhanom Ghebreyesus said, "Nationalism exacerbated the pandemic and contributed to the total failure of the global supply chain," noting shortages of protective gear when the pandemic first hit caused by some nations hoarding resources. The WHO chief said that countries needed to work together to "prevent vaccine nationalism," so in the event a vaccine or vaccines are developed, those at the highest risk will have equal access. .
