Argentina announced it will begin administering doses of Russia's Sputnik V vaccine later this month.

"When the Russian vaccine is in Argentina, the first person to get it will be me,” President Alberto Fernandez said. “I have no doubt in the quality of the vaccine.”

Russia on Saturday began vaccinations with Sputnik V, which hasn't yet gone through the late-stage trials required in the U.S.

Jonathan Greene, deputy assistant secretary for operations and resources at the Department of Health and Human Services, acknowledged in a briefing call that the agency is not able to provide the number of health care workers states are requesting.

HHS and FEMA have been "very judicious" in using and moving health care workers, providing 300 to 400 nationwide, which matches the number deployed during the first surge in the spring, Greene said. Fewer were deployed over the summer, mimicking the case curve.

About 3,100 can be deployed nationally, but Greene admitted the system is designed more for situations like hurricanes than for pandemics.

“It works less well when we're talking about a pandemic where everyone needs all of these providers all at once. And certainly when we activate and deploy these people and take them out of their full-time jobs and put them somewhere else, it reduces the capacity in the places where they come from,” he said.

Greene said the agency has encouraged the use of non-traditional health care providers in order "to bridge the gap."
