Fig. (1) Virus-specific serum and local immune responses in mice after primary vaccination and revaccination with 106 EID50 (H7N3) LAIV or combined LAIV and GBS vaccine (n=8). (a) HI antibodies were detected against A (H7N3) vaccine virus and A/PR8/34 influenza virus. (b) The whole purified A(H7N3) vaccine virus was used for ELISA assay. Reciprocal antibody titers were expressed as log2 (HI) or as log10 (ELISA) and presented as mean±SEM, (*) - p=0.02.
