Similar concerns have risen from both Russia and China claiming to have effective vaccines. Those are being used by their militaries and other high-risk individuals in the population — all before completing, or in some cases even starting, Phase 3 trials.

“I just can’t imagine a scenario by which we would choose to follow Russia and China on anything else,” Kass said.

Dr. Howard Forman, a Yale University professor and health expert, told Yahoo Finance that it would be just like China and Russia if the U.S. were to authorize the use of a vaccine before human trials are complete.

“We have a vaccine now. In fact, we have many vaccines now. We just don’t know if they are safe and effective,” Forman said, adding that the standards of the FDA are what distinguish the U.S. from other countries.

Still, mounting political pressure have stoked concerns among experts over the past several weeks.

“The CDC and the FDA, in the past week, have both had to go back and walk back comments they have made about safety recommendations on testing or therapeutics based on political pressures they’ve had, where they’ve had to correct themselves,” Kass said. “That doesn’t help any public confidence in a vaccine when it comes out.”
