WATCH: CDC chief, health officials testify on COVID-19 vaccine

The Senate Committee on Appropriations held a hearing July 2 on protocols related to a future COVID-19 vaccine.

Watch the hearing in the video player above.

Dr. Francis Collins, Director of the U.S. National Institutes of Health testified that “we are all optimistic” that the Trump administration’s vaccine-acceleration program “Operation Warp Speed” will produce a safe and effective vaccine for COVID-19 by year end, and able to provide 300 million doses by early 2021.

Collins said, “The goal that we have set to have a vaccine that works and is safe by the end of 2020 will be met” by one of the several vaccines candidates.

Collins added that the U.S. is also targeting having 1 million rapid, on-site tests per day sometime around September to enable schools reopening and sports events.

“By fall we expect that the winning technologies will make it possible to deploy several million more tests each week,” he said.
