On Sunday, Surgeon General Dr. Vivek Murthy said, U.S. President Joe Biden will be announcing the new steps to reduce the spread of COVID-19 before the U.N. General Assembly meets.

Although Murthy did not specify what those steps would be. The next session of the General Assembly opens Tuesday; the first day of general debate will be the following week.

Speaking to CNN on Sunday, Murthy defended Biden’s efforts to expand vaccination in the United States, he said, “There will be more actions that we continue to work on, especially in the global front”.

Biden on Thursday said he would require federal workers to be vaccinated against COVID-19 and mandate that large employers either require their workers to be vaccinated or regularly tested.

Biden said the United States had donated 140 million vaccine doses to other countries. “That’s American leadership on a global stage, and that’s just the beginning,” he said.
