IBD vaccines and infection risk: Foundation bridge

Selected Crohn's & Colitis Foundation educational content and Marks are used on IBDPal under license. This page summarizes Foundation guidance on vaccines and infection prevention for people with IBD, especially on immunosuppressive therapy. The Foundation does not endorse IBDPal.

Why vaccines matter in IBD

Immunosuppressants and active inflammation raise infection risks.

Vaccines reduce preventable illnesses that could complicate IBD care. Symptom patterns tracked over several days are more useful to your clinician than a single snapshot.

Plans should be individualized with your GI and primary care. Discuss how this topic applies to your current disease activity with your gastroenterologist. Logging patterns in IBDPal or a notebook helps clinicians see trends beyond a single visit. Your GI team can adjust recommendations based on labs, imaging, and symptom trends. Second opinions are reasonable when plans feel unclear or symptoms persist despite treatment. If symptoms worsen while you try these steps, contact your clinic using your flare pathway. Bring these observations to your next IBD appointment so your team can personalize advice.

Live versus non-live vaccines

Live vaccines may be avoided on some therapies. Timing before starting biologics matters.

Inactivated vaccines such as influenza, pneumococcal, and COVID-19 are commonly recommended. Write down questions for your gastroenterologist before each visit so limited appointment time is used well.

Travel vaccines need advance planning with your team. Bring these observations to your next IBD appointment so your team can personalize advice. Children, older adults, and post-surgical patients may need modified guidance from specialists. Patient education supports shared decision making; it does not replace individual medical assessment.

Screening for latent infections

TB and hepatitis B screening often precedes biologics.

Treat latent TB before starting certain drugs. Medication adherence and follow-up labs are as important as diet changes for many IBD patients.

Repeat screening may be needed when switching therapies. Your GI team can adjust recommendations based on labs, imaging, and symptom trends.

Everyday infection prevention

Hand hygiene, food safety while traveling, and prompt care for fever on immunosuppression are key.

Report shingles, persistent cough, or unusual rashes early. Tell your team about travel, work stress, sleep changes, and menstrual cycle timing when symptoms shift.

Dental and surgical teams need your medication list. Patient education supports shared decision making; it does not replace individual medical assessment.

Family and household considerations

Household members may need certain vaccines to protect immunosuppressed patients.

Discuss newborn and live vaccine exposure with obstetrics when relevant. Bring prior colonoscopy, imaging, and pathology reports when seeing a new IBD specialist.
