People with inflammatory bowel disease often need vaccines more, not less, especially when biologics, immunomodulators, or steroids reduce immune response to infections. Timing and vaccine type matter. This overview follows themes common in CCF and GI society patient education. It is not a personalized immunization schedule.

Why vaccination is part of IBD care

IBD itself and many therapies increase risk for influenza, COVID-19 complications, pneumonia, and reactivation of some latent infections. Staying current on inactivated vaccines is a core safety habit alongside understanding biologics and infection precautions.

Inactivated vaccines commonly discussed

Your team may recommend seasonal influenza vaccine, COVID-19 vaccines per current public health guidance, pneumococcal vaccines, hepatitis B if not immune, Tdap, and other age-appropriate shots. Inactivated vaccines are generally preferred over live vaccines when you are significantly immunosuppressed, but exact decisions belong to your clinicians.

• Bring a vaccine record to GI and primary care visits
• Ask whether titers or booster timing are needed after therapy starts
• Coordinate shots with infusion schedules when possible

Live vaccines need special caution

Live vaccines (examples often discussed include measles-mumps-rubella, varicella, nasal flu spray, and yellow fever for travel) may be unsafe during certain levels of immunosuppression. If a live vaccine is recommended for travel or work, ask your gastroenterologist and travel medicine clinician before scheduling. Sometimes vaccination is ideally completed before starting a biologic; that window is not always available during a severe flare.

Steroids and timing questions

High-dose steroids can blunt vaccine responses and change infection risk. Ask whether to delay a non-urgent vaccine until a steroid taper progresses, or whether to proceed because infection risk is higher than waiting. There is no one rule for every dose and every patient.

Household and travel planning

Family members staying up to date protects you. For international travel, review itinerary vaccines early. See also travel with IBD and IBD care outside the United States for records and logistics.

Questions to ask before your next infusion or injection

• Which vaccines should I complete before escalating immunosuppression?
• Are any live vaccines off-limits on my current regimen?
• Should primary care or GI order pneumonia or hepatitis panels?
• How should I report fever after vaccination versus infection?

Keep a shared list between GI, primary care, and pharmacy. CCF materials encourage proactive vaccine conversations rather than waiting until flu season or a last-minute trip.
