The Centers for Disease Control and Prevention has directed all 50 states and five large cities to make preparations to distribute a potential coronavirus vaccine as soon as late October. In a letter to the nation’s governors, CDC Director Robert Redfield urged states to waive any requirements that would prevent vaccine distribution centers from becoming fully operational by November 1. The government has hired the private company McKesson Corporation to distribute a vaccine once it is approved. There is growing concern that the Trump administration might give emergency approval to a vaccine before clinical tests are completed in an attempt to boost the president’s reelection chances. Public health officials have warned that rushing an unproven vaccine could pose health dangers and inflame anti-vaccination sentiment. This all comes as the U.S. death toll from COVID-19 approaches 186,000.
