Abstract
Continued H5N1 virus infection in humans highlights the need for vaccine strategies that provide cross-clade protection against this rapidly evolving virus. We report a comparative evaluation in ferrets of the immunogenicity and cross-protective efficacy of isogenic mammalian cell-grown, live attenuated influenza vaccine (LAIV) and adjuvanted, whole-virus, inactivated influenza vaccine (IIV), produced from a clade 1 H5N1 6:2 reassortant vaccine candidate (caVN1203-Len17rg) based on the cold-adapted A/Leningrad/134/17/57 (H2N2) master donor virus. Two doses of LAIV or IIV provided complete protection against lethal homologous H5N1 virus challenge and a reduction in virus shedding and disease severity after heterologous clade 2.2.1 H5N1 virus challenge and increased virus-specific serum and nasal wash antibody levels. Although both vaccines demonstrated cross-protective efficacy, LAIV induced higher levels of nasal wash IgA and reduction of heterologous virus shedding, compared with IIV. Thus, enhanced respiratory tract antibody responses elicited by LAIV were associated with improved cross-clade protection.
