If we need a booster dose, does that mean the vaccines are not working?

Booster doses are common for many vaccines, and over time, booster doses may need to be updated to provide optimal protection against new variants of the virus. The scientists and medical experts who developed the COVID-19 vaccines continue to watch for waning immunity, how well the vaccines protect against new mutations of the virus, and how that data differ across age groups and risk factors. To date, booster doses have worked well in extending the protection of the vaccine against serious illness, but have been somewhat less effective in boosting immunity against new variants of COVID-19 compared to the original strain. The updated booster dose formula is designed to protect against original strains of the virus, as well as Omicron variants that account for the majority of current new infections. The latest CDC recommendations on booster doses help to ensure more people across the U.S. are better protected against COVID-19. The best way to protect yourself from COVID-19 is to get vaccinated and boosted if eligible. Vaccination and boosting is particularly important for individuals more at risk for severe COVID-19, such as older people and those with underlying medical conditions.
