The emergence of the Omicron variant of the SARS-CoV-2 virus has sparked a vigorous reaction around the globe, which in the U.S. includes steps taken by the Biden administration to ensure that the roughly 100 million people who have received an initial vaccination regime will receive a booster if eligible. The administration also reported Dec. 2 that it will take steps to ensure that home testing will be covered by private payers, all of which amounts to a massive boost in business for manufacturers of vaccines and tests despite concerns about how the Omicron variant might affect vaccine and test performance.
