"The effort to distribute and administer the vaccine is not progressing as it should," Biden said in Wilmington, Delaware. This revealed eight mutations specific to the spike protein gene associated with the British variant, Polis said in his statement. The Denver-based online news outlet Coloradopolitics.com, citing Elbert County's public health director, later reported that a second suspected case of the variant was under examination there.

The Biden team has stressed the importance of inoculation in non-white communities especially hard hit by the coronavirus and more highly skeptical about vaccine safety.
