Elevated biosynthesis of palmitic acid is required for zebrafish against Edwardsiella tarda infection.

Mechanisms by which vaccines enhance immunity to combat bacterial pathogens are not fully understood. Recently, we have found that live Edwardsiella tarda vaccine enhances ability against the bacterial challenge by metabolic modulation in zebrafish. Here we first explored the metabolic modulation promoted by inactivated E. tarda to eliminate the pathogen. Inactivated E. tarda vaccine modulated a similar metabolome to combat with the pathogen in zebrafish as live E. tarda vaccine did. Specifically, both vacc...

Live-attenuated H1N1 influenza vaccine candidate displays potent efficacy in mice and ferrets.

Currently, influenza vaccine manufacturers need to produce 1-5 x 107 PFU of each vaccine strain to fill one dose of the current live-attenuated-influenza-vaccine (LAIV). To make a single dose of inactivated vaccine (15 ug of each hemagglutinin), the equivalent of 1010 PFU of each vaccine strains need to be grown. This high dose requirement is a major drawback for manufacturing as well as rapidly sourcing sufficient doses during a pandemic. Using our computer-aided vaccine platform Synthetic Attenuated Virus...

Challenges in Evaluating Post-licensure Vaccine Safety: Observations from the Centers for Disease Control and Prevention.

: Vaccination is one of the most successful and cost-effective public health interventions. Although vaccines undergo extensive safety and efficacy evaluations prior to licensure, vaccine safety assessment post-licensure is essential for detecting rare and longer-term adverse events (AEs) and maintaining public confidence in vaccines and recommended immunization programs. Despite the proven effect of vaccines to save lives and prevent disease and overwhelming evidence of vaccines' safety and societal benefi...
