It could take almost 9 more months to vaccinate 70% of Americans against SARS-CoV-2 infection and reach a herd immunity threshold, assuming the current pace of immunizations continues and requires a two-dose regimen with either the Pfizer/BioNTech or Moderna vaccines, a Medscape analysis reveals.
Clinicians have administered a total 44,769,970 doses of COVID-19 vaccine in the United States as of February 11 according to the Centers for Disease Control and Prevention (CDC) COVID Data Tracker. Although the site also reports total US cases of COVID-19, total doses of vaccines delivered, and the number of Americans who have died, the agency doesn’t estimate how long it will likely take to reach certain immunization milestones.
