What the study said: “The omicron coronavirus variant causes less severe disease than the delta strain even in those who are unvaccinated or who haven’t had a prior COVID-19 infection,” per Bloomberg.

Yes, but: The World Health Organization said Wednesday that the omicron variant can be a “dangerous virus” for the unvaccinated, per Reuters.

  • “Omicron still represents a massive threat to their life and a massive threat to their health,” said Dr. Mike Ryan, director of the WHO’s health emergencies program, per CNBC.
  • President Joe Biden said in December that the omicron variant is dangerous for vaccinated people: “For unvaccinated, we are looking at a winter of severe illness and death ... for themselves, their families and the hospitals they’ll soon overwhelm,” Biden added. “But there’s good news. If you’re vaccinated, and you have your booster shot, you’re protected from severe illness and death, period.”
