Project description: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 TIV (6 vaccinees) or LAIV (6 vaccinees), and blood samples isolated at day 0 and at day 7 post-vaccination. Cell subsets (B cells, Monocytes, mDCs and pDCs) were FACS-sorted from frozen PBMCs. Microarrays were performed using amplified total RNA.

Microarrays were performed using total RNA extracted from the peripheral blood mononuclear cells of vaccinees.

Project description:Purpose: Influenza virus infections affect millions of people annually. Current available vaccines provide varying rates of protection. There is a knowledge gap on how the nasal microbiota, particularly established pneumococcal colonization, shapes the response to influenza vaccination. Methods: In this study, we inoculated healthy adults with live S. pneumoniae and vaccinated them three days later with either TIV or LAIV. Vaccine-induced immune responses were assessed in nose, blood and lung. Results: Nasal pneumococcal colonization had no impact upon TIV-induced antibody responses to influenza, which manifested in all compartments. However, pre-existing pneumococcal colonization dampened LAIV-mediated mucosal antibody responses, primarily IgA in the nose and IgG in the lung. Pulmonary influenza-specific cellular responses were more apparent in the LAIV group compared to either TIV or an unvaccinated group. Conclusions: These results indicate that TIV and LAIV elicit differential immunity to adults and that LAIV immunogenicity is diminished by the nasal presence of S. pneumoniae. This important confounder should be considered when assessing LAIV efficacy.

Project description:LAIV and TIV are effective for prevention of influenza infection in children, but the mechanisms associated with protection are still not well defined. We analyzed the differences in B cell responses and transcriptional profiles. Compared to baseline, LAIV elicited a significant increase in naïve, memory and transitional B cells on day 30, while vaccination with TIV elicited an increase in number of plasmablasts on day 7. Antibody titers against the three vaccine strains (H1N1, H3N2 and B) were significantly higher in the TIV group and correlated with number of antibody-secreting cells. Regarding transcriptional profiles, both vaccines induced expression of interferon signaling, but at different time points, TIV on 1 day, and LAIV on day 7 day post-vaccination, the last only in children younger than 5 years old. Interferon-related genes over expressed in both vaccinated groups correlated with antibody titers of H3N2 vaccines strain. These results suggest that LAIV and TIV induced significant different B cell responses in vaccinated children. Early induction on interferon genes appears important for development of effective antibody responses.

Longitudinal study with time points at baseline (day 0), 24hr, day 7 and day 30. 136 total samples analyzed. This was a prospective cohort of previously healthy children 6 months to 14 years of age enrolled between October 2011 and February 2012. Thirty seven subjects were randomized to receive one dose of either LAIV (FluMistM-BM-., MedImmune) (n= 20) or TIV (FluzoneM-BM-., Sanofi Pasteur) (n= 17). Two exceptions were applied to the randomization: four children with ages between 6 months and 2 years old received TIV, since LAIV is not licensed on this age group, and four children with controlled asthma also received TIV following CDCM-bM-^@M-^Ys recommendations. One child aged 6 months at the time of enrollment received two doses of the vaccine with one month interval apart, since it was his first influenza vaccination. Exclusion criteria included any medical comorbidities or chronic conditions (lung, kidney or heart disease), use of systemic steroids in the previous 2 weeks, and congenital or acquired immunodeficiencies. The 2011-2012 LAIV and TIV vaccines contained A/California/7/2009 (H1N1)-like, A/Perth/16/2009 (H3N2)-like and B/Brisbane/60/2008-like antigens, the same strains used on the 2010-2011 influenza vaccine. TIV recipients aged 6 to 35 months old received 0.25 mL intramuscularly and recipients aged 36 months and older received 0.5 mL. LAIV recipients received 0.2 mL by intranasal route, 0.1 mL per nostril. Blood samples were collected at four time points, on day zero prior to vaccination, and day 1, day 7 (range 6-8) and day 30 (range 27-33) post-vaccination.
