156 countries joined a major, WHO-led effort to develop and distribute coronavirus vaccines.
The US and China aren't among them.
In recent weeks, 156 countries have formally signed on to Covax, a major effort spearheaded by the World Health Organization to develop, manufacture, and distribute coronavirus vaccines.
China and the US, however, both opted out.
Instead, the two countries are focusing on funding vaccine research and development on their own, then striking deals with manufacturers to buy the resulting shots.
But Covax is the only global initiative that aims to ensure a vaccine reaches vulnerable people in poorer nations. The countries that have signed on represent 64% of the global population, and 64 of them are wealthier nations like Canada, Germany, and Saudi Arabia.
The US and China's lack of involvement could hamper the program's efforts, experts say.
