No. The updated bivalent formula is in use only for COVID-19 booster doses, and not for initial vaccination. The best way to protect yourself from getting severely ill from COVID-19 is to get vaccinated. The CDC recommends that currently unvaccinated people get their primary series (the initial two doses of either the Pfizer, Moderna, or Novavax vaccines, or one dose of the Johnson & Johnson vaccine), and then wait at least two months to get the updated Pfizer or Moderna booster dose. Adults age 18 and older also have the option to receive a Novavax booster instead of an updated Pfizer or Moderna booster if they are unable to receive mRNA vaccines and haven’t previously received any booster dose.
