Vaccination remains the sole effective strategy for combating Japanese encephalitis (JE). Both inactivated and live attenuated vaccines exhibit robust immunogenicity. However, the production of these conventional vaccine modalities necessitates extensive cultivation of the pathogen, incurring substantial costs and presenting significant biosafety risks.

Introduction: Though COVID-19 as a public health emergency of international concern (PHEIC) was declared to be ended by the WHO, it continues to pose a significant threat to human society. Vaccination remains one of the most effective methods for preventing COVID-19. While most of the antigenic regions are found in the receptor binding domain (RBD), the N-terminal domain (NTD) of the S protein is another crucial region for inducing neutralizing antibodies (nAbs) against COVID-19.

Feline calicivirus (FCV) is one of the most widespread pathogens affecting feline animals. Currently, FCV is believed to be divisible into two genotypes, with prevalent strains encompassing both GI and GII. Vaccination is the primary means of preventing FCV infection, yet traditional inactivated or attenuated vaccines theoretically pose potential safety concerns.

Introduction: Pandemic influenza vaccine development focuses on the hemagglutinin (HA) antigen for potency and immunogenicity. Antibody responses targeting the neuraminidase (NA) antigen, or the HA stalk domain have been implicated in protection against influenza. Responses to the NA and HA-stalk domain following pandemic inactivated influenza are not well characterized in humans.

Unlabelled: Neuraminidase (NA)-specific antibodies contribute to immunity against influenza. While studies have demonstrated increased NA inhibiting (NAI) antibody titers after vaccination with egg-derived inactivated influenza vaccines (eIIV), the response to cell culture-derived (c) IIV has not been reported.
Methods: An immunogenicity sub-study was performed within a clinical trial comparing the effectiveness of egg, cell, and recombinant hemagglutinin (HA)-derived influenza vaccines during the 2018-2019 and 2019-2020 influenza seasons.
