摘要: The worldwide incidence of rabies and the inability currently used vaccination strategies to provide highly potent cost-effective therapy indicate need for an improved vaccine. Thus, DNA vaccine based on lysosome-targeted glycoprotein virus was evaluated in BALB/c mice. It imparted partial protection (60%) against challenge with 20 LD50 standard (CVS) strain virus. To improve outcome vaccination, ultimately enhance immune response, we investigated different routes delivery, varied doses DNA, influence adjuvant supplementation. highest response pertaining IgG antibody titer, a predominantly IgG1/IgG2a subclass distribution, effective cellular immunity, high level neutralizing antibodies (RVNAs) attained by optimized formulation comprising intramuscular administration 100 μg supplemented Emulsigen®-D. In preexposure p...
