Robert Redfield, director of the U.S. Centers for Disease Control and Prevention (CDC), estimated that a vaccine for the disease caused by the novel coronavirus, COVID-19,
will likely be available (WSJ) to the U.S. public in the late second or third quarter of 2021. A limited supply that could be made by the end of 2020 would be prioritized for high-risk people and first responders, Redfield told a Senate subcommittee. He also encouraged the use of masks.
President Donald J. Trump pushed back, saying a vaccine could be
ready in weeks (NYT) for immediate public distribution, though multiple vaccine experts have disputed that timeline. Trump also
questioned the effectiveness (WaPo) of masks, which have been shown to limit the virus’s spread. Daily U.S. coronavirus infections have risen to roughly 40,000, and the country has recorded
almost 197,000 total virus-related deaths (CNN).
