Are the vaccines effective against this variant?

Studies are underway to answer that question. While it is possible that current vaccines may be less effective against the Omicron variant, vaccine availability is limited in many African countries, and South African officials are reporting that most of the people there who are sick due to the omicron variant were not vaccinated. Vaccines remain widely available in the U.S. and the Omicron variant is yet another reason to get vaccinated and get a booster if you are eligible.
