An effective vaccine is needed to reduce HIV infections, particularly among younger people. The initiation of an HIV vaccine regimen in early life could allow the development of mature HIV‑specific antibody responses that protect against infection. The investigators compared the effects of two vaccine regimens in infant rhesus macaques (sex not specified). Both vaccines induced a rapid innate response, indicated by elevated inflammatory plasma cytokines and altered gene expression. By performing a network analysis, the investigators identified differentially expressed genes associated with B cell activation. These findings suggest that vaccine-induced immunity can be optimized by modulating specific antibody and T cell responses. Supported by ORIP (P51OD011107), NCI, NIAID, and NIDCR.
