Results from LimitationRecognizer: We detected the following sentences addressing limitations in the study:Some limitations of our study are the small numbers of study subjects in some of the groups and grouping together of drugs by class. T cell responses, including IL-4, IL-2 and IFN-γ production, showed a significant correlation with RBD and spike - specific antibody responses. There was substantial induction of T cell cytokines and release of cytotoxic molecules following spike peptide pool stimulation of PBMCs collected following one dose of vaccine. Some subgroups and parameters showed increases in T cell cytokines with two doses. Multivariate analysis of the data showed that several groups had decreased IFN-γ after dose 1 of vaccine, but these deficits were largely corrected following the second vaccine dose. When data were pooled for all subjects, it was apparent that the IL-4 response was particularly dependent on 2 doses of vaccine and showed a waning trend 3 months later. As IL-4 is an important mediator of B cell proliferation, which in turn impacts antibody levels and B cell memory,28 the lower IL-4 response after 1 dose as compared to 2 doses of vaccine highlights the need for second doses to maximize B cell responses. Taken together, our study shows generally robust T cell responses in most patient groups treated with immunosuppressants or biologics after 1 or 2 doses of mRNA vaccine, improving somewhat with a second dose but with some attenuation by 3 months after the second dose. We observed some deficits in antibody responses even after two doses of vaccine, part...
