The Illinois Department of Public Health (IDPH) is adopting the Centers for Disease Control and Prevention (CDC) recommendation to shorten the interval from 6 months to 5 months for when
people who have received the Pfizer-BioNTech COVID-19 vaccine can get a booster dose. This only applies to those who received two doses of Pfizer-BioNTech vaccine during their primary
series. These individuals may receive either FDA authorized mRNA vaccine (Pfizer or Moderna) for their booster dose. The booster interval remains the same for both the Moderna
vaccine (6 months) and the Johnson & Johnson (J&J) vaccine (2 months).

The CDC Media Release, including a statement from CDC Director Rochelle Walensky, can be found here. Additionally, CDC is recommending that moderately or severely immunocompromised children aged 5-11 years receive a third dose of vaccine 28 days after their second dose. IDPH also adopts these recommendations. At this time, only Pfizer-BioNTech is authorized for children. Parents of immunocompromised children should talk with their pediatrician or health care provider about a potential third dose.

On Monday (01/03/22), the Food and Drug Administration also authorized booster doses for those aged 12- 15 years and the CDC will discuss this later this week. IDPH will further communicate recommendations upon release of the CDC recommendations. The Pfizer-BioNTech COVID-19 Vaccine Provider and Recipient/Caregiver Fact Sheets have been updated following the FDA’s amendments on 01/03/2022. The EUA fact sheets can be found here.
