WHEN the World Health Organization declared the coronavirus a pandemic one year ago Thursday, it did so only after weeks of resisting the term and maintaining that the highly infectious virus could still be stopped. A year later, the UN agency is still struggling to keep on top of the evolving science of COVID-19, to persuade countries to abandon their nationalistic tendencies and help get vaccines where they’re needed most. The agency made some costly missteps along the way: It adviced people against wearing masks for months and asserted that COVID-19 wasn’t widely spread in the air. It also declined to publicly call out countries — particularly China — for mistakes that senior WHO officials grumbled about privately.

 

That created some tricky politics that challenged WHO’s credibility and wedged it between two world powers, setting off vociferous Trump administration criticism that the agency is only now emerging from. President Joe Biden’s support for WHO may provide some much-needed breathing space, but the organisation still faces a monumental task ahead as it tries to project some moral authority amid a universal scramble for vaccines that is leaving billions of people unprotected. “WHO has been a bit behind, being cautious rather than precautionary,” said Gian Luca Burci, a former WHO legal counsel now at Geneva’s Graduate Institute. “At times of panic, of a crisis and so on, maybe being more out on a limb — taking a risk — would have been better.” WHO waved its first big warning flag on January 30, 2020.
