Vaccine booster doses can provide extra protection against COVID-19, especially for those who are most vulnerable to serious illness, including seniors and people with underlying health conditions. Booster doses do a good job of ​strengthening protection against COVID-19​ ​that may have started to wane after initial vaccination. 

Chicagoans can get a booster dose at sites across the city – in hospitals, physicians’ offices, local pharmacies, through Protect Chicago At Home, at pop-up clinics hosted by the City, and more.

No, all three COVID-19 vaccines continue to be very effective in preventing hospitalization and death from COVID-19. However, the CDC has said the protection provided by the vaccine could wane over time, especially among those in the oldest age groups or who have underlying medical conditions.

This depends on the vaccine. Pfizer and Johnson & Johnson booster doses are the same as the initial vaccine doses. For Moderna, it is half the dose of the vaccine people get for their initial series.

Individuals age 5 and older should get a Pfizer COVID-19 vaccine booster. Individuals 18 years and older may choose among any of the COVID-19 vaccines as a booster dose. Some people may have a preference for the vaccine type that they originally received and others may prefer to get a different booster. CDC’s recommendations now allow for this type of mix and match dosing for booster shots.

COVID-19 vaccines are available for everyone at no cost, including the booster shot. Vaccines will continue to be given to all eligible people living in Chicago, regardless of insurance or immigration status.

Individuals can self-report that they are eligible and receive a booster dose wherever vaccines are offered. This will help ensure there are not additional barriers to access for this vulnerable population receiving their booster.

Yes. Up to date means a person has received all recommended doses of a COVID-19 vaccine, including any booster dose(s) when eligible.

Yes, if a patient is eligible, both flu and COVID-19 vaccines can be administered at the same visit, as recommended by CDC and ACIP. In addition to flu vaccine, COVID-19 vaccine can be given with other vaccines as well.
