background: nanoparticles have been considered as promising tools because of their high applicability. recently, nanoparticles have been evaluated for their ability to increase the immune responses as adjuvants. silver-nanoparticles (agnps) have shown promising results in enhancing th-2 immune responses and to produce potent neutralizing antibodies. neutralizing antibodies are considered as the...

The choice of adjuvants is critical for any vaccine whether prophylactic or therapeutic. Our group previously showed that incomplete Freund’s adjuvant, commonly used in different cancer vaccine trials, had many undesirable effects on T cell trafficking and function which directly translates into poor anti-tumor efficacy in preclinical murine model. Switching from oil-based (IFA) to water based ...

Enteric redmouth disease (ERM) caused by the fish pathogen Yersinia ruckeri is a major threat to freshwater production of rainbow trout throughout all life stages. Injection vaccination of rainbow trout against Y. ruckeri infection has been shown to confer better protection compared to the traditionally applied immersion vaccination. It may be hypothesized, based on experience from other vaccin...

compared to other methods of vaccine production, (e.g. culture flask and bioreactor system), the roller culture method for producing rabies vaccine is simpler, and the equipment easier to install and maintain, and also in the event of contamination of one roller, the entire batch need not be discarded. this system provides a much larger surface area than the culture flask, and also ensures a mu...

The induction and modulation of the immune response to vaccination can be rationally designed by combining different vaccine formulations for priming and boosting. Here, we investigated the impact of heterologous prime-boost approaches on the vaccine-specific cellular and humoral responses specific for a mycobacterial vaccine antigen. C57BL/6 mice were primed with the chimeric vaccine antigen H...

The antibody response to various combined polyvalent Pasteurella haemolytica vaccines was studied in sheep and cattle. In sheep, certain oil adjuvant vaccines gave rise to a better antibody response to P. haemolytica than an A1(OH)3-adsorbed vaccine. This finding, however, was not consistent for all serotypes, and with respect to P. multocida, oil adjuvants had no advantage. Furthermore, it was...

The ongoing threat from Influenza necessitates the development of new vaccine and adjuvant technologies that can maximize vaccine immunogenicity, shorten production cycles, and increase global vaccine supply. Currently, the most successful adjuvants for Influenza vaccines are squalene-based oil-in-water emulsions. These adjuvants enhance seroprotective antibody titers to homologous and heterolo...

introduction: influenza can cause more severe diseases and higher rate of morbidity and mortality in the elderly population. therefore, they should receive influenza vaccine annually. however, the host response to vaccine is less in older individuals. on the other hand, selenium can act as a stimulator of the immune system and cause increased immunity and response to vaccine. this study was car...
