Time Course of Young Adults Vaccinated with Influenza LAIV Vaccine during 2008/09 Flu Season

Systems vaccinology has emerged as an interdisciplinary field that combines systems wide measurements and network and predictive modeling applied to vaccinology. Here we used the systems vaccinology approach to study the molecular mechanisms underlying the innate responses to the trivalent inactivated influenza (TIV) and live attenuated influenza (LAIV) vaccination in humans, and to identify early gene signatures that predict the magnitude of the antibody responses to influenza vaccination. During the 2008 influenza season, healthy adults were vaccinated with LAIV (28 vaccinees), and blood samples isolated at days 0, 3, 7 post-vaccination. Microarrays were performed using total RNA extracted from the peripheral blood mononuclear cells of vaccinees.
