Oakes et al., evaluated cellular and humoral immune responses after influenza vaccinations in adults. Vaccination elicited comparable serologic responses; however, adults 65 years old and over had reduced cellular immune responses, and single-cell RNA sequence analysis revealed that they had attenuated IFN transcriptional signatures in T-helper and myeloid cell subsets.
