IDPH also aligns with the CDC Advisory Committee on Immunization Practices’ (ACIP) recommendation for a booster shot of COVID-19 vaccines in certain populations.

The Food and Drug Administration’s (FDA) and CDC’s recommendation for use are important steps forward as we work to stay ahead of the virus and keep Illinoisans safe.

For individuals who received a Pfizer-BioNTech or Moderna COVID-19 vaccine, the following groups are eligible for a booster shot at 6 months or more after their initial series:

65 years and older

Age 18+ who live in long-term care settings

Age 18+ who have underlying medical conditions

Age 18+ who work or live in high-risk settings

For the nearly 15 million people who got the Johnson & Johnson COVID-19 vaccine, booster shots are also recommended for those who are 18 and older and who were vaccinated two or more months ago.

Of Illinois’ total population, more than 69 percent has received at least one COVID-19 vaccine dose and 54 percent of Illinois’ total population is fully vaccinated.
