CLINICAL TRIAL OF THE PANDEMIC INFLUENZA MONOVALENT VACCINE PANDEFLU
Abstract. Evaluation of reactogenicity, safety and immunogenicity of the inactivated subunit influenza vaccine adsorbed monovalent (Pandeflu) on the base of strain A/California/7/2009 (H1N1v) was conducted in 70 volunteers aged 18–60 years immunized by one or two doses. A clinical trial of the vacci...
