RT Journal Article T1 Characterization of the immune response induced by a commercially available inactivated bluetongue virus serotype 1 vaccine in sheep A1 Pérez de Diego, Ana Cristina A1 Sánchez Cordón, Pedro José A1 Heras, Ana Isabel de las A1 Sánchez-Vizcaíno Rodríguez, José Manuel AB The protective immune response generated by a commercial monovalent inactivated vaccine against bluetongue virus serotype 1 (BTV1) was studied. Five sheep were vaccinated, boost-vaccinated, and then challenged against BTV1 ALG/2006. RT-PCR did not detect viremia at any time during the experiment. Except a temperature increase observed after the initial and boost vaccinations, no clinical signs or lesions were observed. A specific and protective antibody response checked by ELISA was induced after vaccination and boost vaccination. This specific antibody response was associated with a significant increase in B lymphocytes confirmed by flow cytometry, while significant increases were not observed in T lymphocyte subpopulations (CD4(+), CD8(+), and WC1(+)), CD25(+) regulatory cells, or CD14(+) monocytes. After challenge with BTV1, the antibody response was much higher than during the boost vaccination period, and it was associated with a significant increase in B lymphocytes, CD14(+) monocytes, CD25(+) regulatory cells, and CD8(+) cytotoxic T lymphocytes.
