U.S. Army officials announced last week that the Medical Research and Development Command (USAMRDC) is closing in on human trials for a coronavirus vaccine. 

The command has been quietly working on its own vaccine candidates as part of President Trump’s Operation Warp Speed, according to Col. Stuart Tyner, director of Military Infectious Diseases Research Program. 

Operation Warp Speed is the administration’s aggressive plan to counter the virus that continues to rage across the country and has led to the deaths of over 220,000 Americans and the infection of 8.3 million. One of the key objectives of the operation is the creation and distribution of some 300 million vaccines.

The command is reportedly working hand in hand with private companies in an effort to accelerate the vaccine timeline. “We do have a vaccine that we’ve been working towards maturing and developing,” Tyner said.
