Simple Blind, Placebo Controlled, Randomized Safety and Reactogenicity Trial of "Baby-Hib [Vaccine for the Prevention of Infections Caused by Haemophilus Influenzae Type b], Lyophilizate for Preparation of Intramuscular Injection Solution, 0.5 mL/Dose", FSUE SPbSRIVS FMBA of Russia, in Volunteers Aged 18-50

Trial purpose is to evaluate the safety, tolerability and reactogenicity of the Vaccine for the prevention of infections caused by Haemophilus Influenzae Type b in volunteers aged 18-50.

Study Overview

• Status: Completed
• Conditions: Vaccines; Haemophilus Influenzae Infection
• Intervention / Treatment: Biological: Vaccine for the prevention of infections caused by Haemophilus influenza type b; Biological: Placebo

Detailed Description

The trial includes 2 stages (Stage I and Stage II). The aim of the Stage I is to assess the tolerability, reactogenicity and safety of the Hib vaccine in the first 10 volunteers during the first 7 days after vaccination.

The aim of the Stage I is to assess the tolerability, reactogenicity and safety of the Hib vaccine during 28 days after vaccination and also to conduct a comparative assessment of the safety and reactogenicity of the Hib vaccine and placebo during 28 days after vaccination.
