Induction of immune responses against rotavirus by intramuscular and intranasal immunization with rotavirus DNA vaccine / 重庆医科大学学报

ABSTRACT

Objective:To search for the efficient immune routes for rotavirus DNA vaccine by evaluating efficacy in inducing immune responses to rotavirus.Methods:In this study BALB/c mice were immunized by intramuscular and intranasal routes with rotavirus DNA vaccine,pcDNA 1/VP7,then rotavirus specific systemic immunity was measured.Results:Serum rotavirus specific IgG but not IgA titers of mice immunized by both routes were significantly higher than that of the unimmunized controls.Conclusion:Both intramuscular and intranasal routes are candidates for rotavirus DNA vaccine.
