Yes. Vaccines remain the best measure to protect from COVID-19, as well as reduce the likelihood of new variants emerging. COVID vaccines are particularly effective in preventing serious illness, hospitalization, and death, even with breakthrough cases being reported as a result of the Omicron variant. CDC recommends that everyone ages 18 years and older should get a booster shot at least two months after their initial J&J/Janssen vaccine or six months after completing their primary COVID-19 vaccination series of Pfizer-BioNTech or Moderna in order to best protect against new COVID variants.
