Clinical Trial Summary

This study will evaluate the effect of the microorganisms in the gut on how well the flu or COVID-19 vaccine works in people who have a weakened immune system due to inflammatory bowel disease. Participants can expect to be in the study for up to 65 days.

Description:

The overall objective of this study is to evaluate the role of gut microbiome in influenza or COVID-19 vaccine response in immunosuppressed populations. Microbial diversity (alpha diversity) is decreased in immunosuppressed patients and might be associated with lower immunogenicity to vaccines.

It is known that patients with IBD have dysbiosis of their gut microbiome and those immunosuppressed may have a lower vaccine response. In this aim, the investigators will evaluate whether differences in microbial diversity predict immune response to the influenza and COVID-19 vaccine.

In this prospective study, immunosuppressed IBD patients will be vaccinated per standard of care and blood will be collected to measure the immune response. A fecal and saliva sample will be collected to characterize the gut microbiome. The investigators hypothesize that reduced richness / alpha-diversity in gut microbiota will correlate with those with a blunted vaccine response.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Influenza or COVID-17 antibody concentrations	Hemagglutination inhibition assay (HIA) will be used to measure influenza antibodies in blood. COVID-19 antibody concentration analysis will be completed with LabCorp's Cov2Quant IgG™ assay which uses immunoassay that uses electrochemiluminescent technology (ECL) for quantitative determination of anti-receptor binding domain (RBD) IgG antibodies specific to SARS-CoV-2.

One blood draw between 28-65 days after baseline
Primary	Microbiome metrics	Microbiome metrics will include phylogenetic diversity, and analyses of relative abundance of microbes using 16SrRNA gene sequence data from fecal material. Alpha diversity of the microbiome will be evaluated.	One stool collection between days 0-65
Primary	Microbiome stability	Microbiome stability will be evaluated using hierarchical clustering of weighted and unweighted UniFrac distances (a beta diversity metric indexing compositional similarity/difference) for microbiome using 16SrRNA gene sequence data from fecal material.	One stool collection between days 0-65
Secondary	Correlation between Fecal Metabolomic Activity and Vaccine Response		up to 65 days
Secondary	Correlation between Saliva DNA and Vaccine Response		up to 65 days
