Measure Description |
Time Frame |
|---|---|---|
|
Serologic protection
Time Frame: 28 days ± 3 days after influenza vaccination
|
To compare the proportion of IBD patients on maintenance infliximab who mount serologic protection to each component of the influenza vaccination between patients vaccinated on day of infliximab infusion (Day 0 to 4) and patients vaccinated at the mid-point between infliximab infusions (Day 21 to 28).
Serologic protection will be defined by a hemagglutination-inhibition titer ≥ 1:40.

28 days ± 3 days after influenza vaccination

Immunogenic response
Time Frame: 28 days ± 3 days after influenza vaccination
|
To compare the proportion of IBD patients on maintenance infliximab who mount an immunogenic response to each component of the influenza vaccination between patients vaccinated on day of infliximab infusion (Day 0 to 4) and patients vaccinated at the mid-point between infliximab infusions (Day 21 to 28).
Immunogenicity will be defined as a fourfold or greater differences in titer between pre and post-vaccination sera.

Number of participants with serious adverse events
Time Frame: 3 days post vaccination
|
To evaluate the number of participants with early serious adverse reactions (≤ 3 days post-vaccination)
|
3 days post vaccination

|
Change in disease activity from baseline
Time Frame: Four week post-vaccination
|
To evaluate the change in disease activity score from baseline using the validated instruments of the Pediatric Ulcerative Colitis Activity Index for participants with Ulcerative Coltiis and the Harvey Bradshaw Index for participants with Crohn's Disease
|
Four week post-vaccination
