FREQUENTLY ASKED QUESTIONS

For individuals who received a Pfizer-BioNTech or Moderna COVID-19 vaccine, everyone age 18 or older is now eligible to receive a booster at 6 months or more after their initial series.

For individuals who received the Johnson & Johnson COVID-19 vaccine, booster shots are recommended for those who are 18 and older and were vaccinated 2 or more months ago.

People who are moderately to severely immunocompromised should consult with their specialty provider about timing and dosage of vaccines.

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. 

Hundreds of pharmacies and healthcare providers throughout the city are offering vaccine booster doses. Effective October 25, Pfizer and J&J booster doses will also be offered at all CDPH pop-up clinics and events, including joint flu-COVID vaccination clinics, and through Protect Chicago At Home, the City’s in-home vaccination program.

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.

Eligible individuals may choose which vaccine they receive 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 shot wherever vaccines are offered. This will help ensure there are not additional barriers to access for this vulnerable population receiving their booster shot.

No. At this time, people are still considered fully vaccinated two weeks after their second dose in a 2-dose series, such as the Pfizer or Moderna vaccines, or two weeks after a single-dose vaccine, such as the J&J/Janssen vaccine.

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.
