The US Centers for Disease Control and Prevention (CDC) has asked states to be ready to distribute a potential coronavirus vaccine by as soon as November 1.
In a letter to state Governors and health departments on Wednesday, CDC Director Robert Redfield said the McKesson Corporation and its subsidiaries would soon be applying for permits to build distribution sites. He asked the Governors to consider waiving requirements that would delay construction or opening the sites. In the letter Redfield quoted,
CDC urgently requests your assistance in expediting applications for these distribution facilities and, if necessary, asks that you consider waiving requirements that would prevent these facilities from becoming fully operational by November 1.
Three different vaccines are currently in Phase 3 trials in the U.S., during which the vaccine is given to thousands of people to test its safety and efficacy.
Some scientists warn that granting emergency authorization to a vaccine before clinical trial is potentially dangerous while others say that doing so could save thousands of lives. A spokesperson from CDC said,
At this time, we don't know which vaccines will be approved, however, limited COVID-19 vaccine doses may be available by early November 2020 and COVID-19 vaccine supply will increase substantially in 2021.
