The World Health Organization chief hailed Monday “encouraging” news about COVID-19 vaccines but expressed concern about surging cases in many countries and insisted that complacency was not an option.
“We continue to receive encouraging news about COVID-19 vaccines and remain cautiously optimistic about the potential for new tools to start to arrive in the coming months,” WHO chief Tedros Adhanom Ghebreyesus told a virtual press briefing.
But he added: “This is no time for complacency.”
His comments came as global hopes of overcoming the coronavirus pandemic were boosted after a second candidate vaccine was found to be nearly 95 percent effective in an ongoing trial.
The news from the US biotech firm Moderna brought much-needed optimism to a world facing surging infections and grueling new restrictions.
