Experts estimate that 11 billion doses are necessary to reach widespread global immunity. Before Wednesday, the United States had promised to donate more than 600 million doses. The additional 500 million that Mr. Biden pledged brings the total U.S. commitment to 1.1 billion doses, more than any other country.

“Put another way, for every one shot we’ve administered to pay in America, we have now committed to do three shots to the rest of the world,” Mr. Biden said.

But activists, global health experts and world leaders say donated doses will not be enough. They are calling for the Biden administration to do more to scale up global manufacturing of vaccines, particularly in Africa, where the need is greatest.

“The Covid-19 pandemic reminds us of the importance of diversification of production centers across the world,” President Joko Widodo of Indonesia, which has suffered one of the biggest surges in cases, said in his General Assembly speech. “We know that no one is safe until everyone is.”

selling — rather than donating — its vaccine to other countries.

“We should unite around the world on a few principles: that we commit to donating, not selling — donating, not selling — doses to low- and lower-income countries, and that the donations come with no political strings attached,” the president said.

He also announced a vaccine partnership with the European Union and said the United States was working to scale up production overseas through a partnership with India, Japan and Australia that was “on track to produce at least 1 billion vaccine doses in India to boost the global supply by the end of 2022.”

The doses the Biden administration is donating, however, have been trickling out slowly. So far, 157 million have been shipped overseas. Dr. Peter J. Hotez, an infectious disease expert at Texas Children’s Hospital who helped develop a coronavirus vaccine that is being manufactured in India, said the president should have laid out “a frank articulation of the magnitude” of the shortage.

“We don’t need it by 2023,” Dr. Hotez said. “We need it now, over the next six to eight months.”
