Aim The objective of the present study was to prepare a trivalent inactivated vaccine of Newcastle disease virus (NDV), H5N1, and H9N2 viruses. Materials and Methods Three monovalent and a trivalent vaccines were prepared by emulsifying inactivated NDV (LaSota strain), reassortant H5N1, and H9N2 viruses with Montanide ISA 71 oil adjuvant. Parameters used for evaluation of the efficacy of the ...

This is the second phase 1 study of a respiratory syncytial virus (RSV) vaccine containing RSV fusion protein (sF) adjuvanted with glucopyranosyl lipid A (GLA) in a squalene-based 2% stable emulsion (GLA-SE). In this randomized, double-blind study, 261 subjects aged ≥60 years received inactivated influenza vaccine (IIV), a vaccine containing 120 μg sF with escalating doses of GLA (1, 2.5, or 5 ...

BACKGROUND Universal vaccination of children 6 to 59 months of age with trivalent inactivated influenza vaccine has recently been recommended by U.S. advisory bodies. To evaluate alternative vaccine approaches, we compared the safety and efficacy of intranasally administered live attenuated influenza vaccine with those of inactivated vaccine in infants and young children. METHODS Children 6 t...

In the present study the effect of the locally produced genetic adjuvant of ginea pig specific CpG-motif-containing oligodeoxynucleotide (CpG-ODN) in an inactivated FMD virus vaccine was evaluated. Boosting the ginea pigs with FMD vaccine along with CpG-ODN adjuvant produced relatively higher ratio (5-fold) of FMDV-specific IgG2a / IgG1 than those vaccinated in the absence of CpG-ODN. The neutr...

*Correspo Engineer USA. E-mail: v We evaluate the feasibility of electrospinning oil-in-water type emulsions. The emulsions had an aqueous solution of polyethylene oxide (PEO) as the continuous phase, and either mineral oil or a polystyrene (PS) in toluene solution as the drop phase. The Taylor cones and electrified liquid jets were stable even when the emulsion drops were as large as a few-ten...

Oil-in-water emulsions have been successfully used to increase the efficacy, immunogenicity, and cross-protection of human vaccines; however, their mechanism of action is still largely unknown. Nlrp3 inflammasome has been previously associated to the activity of alum, another adjuvant broadly used in human vaccines, and MyD88 adaptor protein is required for the adjuvanticity of most Toll-like r...

The bolus intravenous injection of a novel medium-chain triglyceride:fish oil emulsion (MCT:FO, 8:2, w:w) was recently found to increase within 60 min the leucocyte and platelet phospholipid content of long-chain polyunsaturated omega3 fatty acids. The present report deals with the effects of bovine milk lipoprotein lipase on the lipid composition of this emulsion. The results are compared to t...

Due to a large number of mutations in the spike protein and immune escape, Omicron variant (B.1.1.529) has become predominant concern (VOC) strain. To prevent disease, we developed candidate inactivated vaccine (Omicron COVID-19 Vaccine (Vero Cell), Inactivated). evaluate safety vaccine, tested repeat-dose toxicity Sprague-Dawley (SD) rats. The doses were administered randomly three groups: phy...

We report a parallelized capillary microfluidic device for enhanced production rate of monodisperse polymersomes. This device consists of four independent capillary microfluidic devices, operated in parallel; each device produces monodisperse water-in-oil-in-water (W/O/W) doubleemulsion drops through a single-step emulsification. During generation of the double-emulsion drops, the innermost wat...
