Thank you for quoting. While ACIP faces changes, medical evidence remains constant. New ACG guidelines reinforce that IBD patients need vaccines, screenings & preventive care. Trust your healthcare team—preventive health still matters most. @AmCollegeGastro.

Good to know GI societies and many other medical societies are stepping up and recommending vaccines for their patients! Now its our time to be vocal and still strongly recommend vaccines. @AmerGastroAssn @ASGEendoscopy @CrohnsColitisFn @uw_GIHep @UWHealth @uwsmph @uw_medicine.

Vaccines save lives. And in times like these, clear, evidence-based guidance matters more than ever. #OurAMA joins 79 medical societies to reaffirm that vaccines for flu, COVID-19 & RSV are vital to preventing serious illness. #VaccinesWork.

Read a summary of today ACIP meeting. Worrisome. Read to stay informed of what's being said so you can provide recommendations to your patients. Since ACIP recommendation may change. @AmCollegeGastro @AmerGastroAssn @AASLDtweets .

7) At this time, for someone with IBD who has not been immunized against measles with an MMR vaccine , I would recommend holding immunosuppressive therapy and consulting with both their gastroenterologist and infectious disease specialist.

6) While small studies have shown live vaccines may be safe in IBD patients, we need more studies evaluating their safety. For now, caution is warranted.

5) I'm not recommending using serologic titers to evaluate for vaccine immunity in those with previous known immunization history.

4) Our research shows that patients with IBD on immunosuppressives maintain comparable MMR antibody levels to healthy controls, supporting ACIP guidance to use immunization records rather than serologic testing to determine immunity.

3) What does this mean for patients with Inflammatory Bowel Disease (IBD)?.Important: Live vaccines (like MMR) are not generally recommended for patients with IBD, particularly those on immune modifying therapy.

2) Tragically, we've seen one death of an unvaccinated child due to measles. As of last week, 164 measles cases have been reported across the U.S. VACCINATION STATUS:.95% of cases unvaccinated individuals or unknown status.Only 3% had one MMR dose.Only 2% had two MMR doses.
