Vaccinations in Crohn’s Disease
Most vaccines are the same as for any teen, with a few that need extra planning.
With only a few exceptions, you should follow the same vaccination schedule as the rest of the pediatric and adolescent population. Your medical team will know which vaccines are recommended for individuals with Crohn’s disease.
The main thing to keep in mind: live virus vaccines should be avoided if you are immunocompromised or planning to start specific medications.
Why Vaccinations Matter
Don’t they have the opposite effect?
It’s a common worry, but the answer is no. If your medications weaken your immune system, you’re more prone to severe infections, which is exactly why staying protected matters.
The flu and other illnesses can hit harder when your immune system is being treated, so vaccines do the opposite of harm: they protect you when you need it most.
Recommended Vaccinations
Routine for teens
Check that your childhood vaccinations are up-to-date
Age- and situation-specific vaccines
Pneumococcus, for the general population: usually under 5 or over 65.
Also for some teens and adults: Pneumococcus is also recommended for people of any age who take medications that suppress the immune system. Your medical team will let you know if this applies to you.
Shingrix (shingles): may be recommended for immunocompromised patients age 19 and up; ask your team if it applies to you.
Only for patients without immunosuppression
These are live vaccines, so they are only safe if you are not immunocompromised:
• MMR (measles, mumps, rubella)
• Varicella (chickenpox)
• The nasal spray flu vaccine (the flu shot is used instead)
Important: Only safe if you are not currently taking medications that suppress your immune system. Always check with your medical team first.
Live Virus Vaccines: A Quick Note
If you are immunocompromised or about to start a medication that affects your immune system, live virus vaccines should be avoided. Whenever possible, your medical team will plan ahead so you can receive any needed live vaccines before starting these treatments, usually at least 4 weeks before the first dose.
After stopping medications that suppress the immune system, live vaccines usually wait between 1 and 3 months, depending on which medication you were taking. Your medical team decides if and when any vaccine is safe for you.
