CDPH Statement on COVID-19 Booster Shots

November 19, 2021

COVID-19 Joint Information Center

After receiving approval from the FDA, the Centers for Disease Control and Prevention (CDC)’s Advisory Committee on Immunization Practices (ACIP) expanded upon their previous recommendation and has approved and recommends a third “booster” dose for anyone age 18 or older who received a Pfizer and Moderna COVID-19 vaccine. Moderna and Pfizer boosters should be received at least six months after completing an initial COVID-19 vaccine series. For those who received a J&J/Janssen COVID-19 vaccine, a reminder that it is recommended that everyone should receive a booster dose at least two months after their initial shot.


The Chicago Department of Public Health supports this decision and encourages all eligible Chicagoans to get their booster dose as we head into the winter months and holiday season. We are ordering more vaccine from the federal government in anticipation of increased demand and remind Chicagoans that they can get a dose at sites across the city – in hospitals, physicians’ offices, local pharmacies, pop-up clinics hosted by the City, and more.
