Efficient protection of mice from influenza A/H1N1pdm09 virus challenge infection via high avidity serum antibodies induced by booster immunizations with inactivated whole virus vaccine
The immunogenicities of inactivated whole and split virus vaccines derived from influenza A/H1N1pdm09 virus were compared in a mouse model. We demonstrated the unique properties of whole virus vaccine boosters on the serum memory antibody response in mice. Consistent with previous studies, booster i...

| description | The immunogenicities of inactivated whole and split virus vaccines derived from influenza A/H1N1pdm09 virus were compared in a mouse model. We demonstrated the unique properties of whole virus vaccine boosters on the serum memory antibody response in mice. Consistent with previous studies, booster immunization with either whole or split virus vaccines of A/H1N1pdm09 virus produced comparable titers of serum antibodies with hemagglutination inhibition and virus-neutralizing activities. However, superior protection against the challenge infection was unexpectedly observed in mice primed and boosted with whole virus vaccines compared with those treated with split virus vaccines, despite similar levels of antibody titers in each group. Immune serum antibodies were shown to be primarily responsible for this protection via passive transfer experiments of immune serum antibodies to naive recipient mice. Moreover, this protection correlated with elevated affinity maturation of the antibodies. Thus, booster immunization with whole virus vaccines elicited a robust serum antibody response with high avidity to the virus, which was not measurable via conventional serological assays. |
