Study information
Scientific title
Clinical trial of safety (reactogenicity) and immunogenicity of needle-free jet injection of reduced-dose, intradermal, Influenza vaccine (INF) administered to more than or equal to six month- to less than 24 month-old infants and toddlers in the Dominican Republic
Acronym
Study hypothesis
Intradermal administration of a fraction (40%) of a dose of influenza vaccine with a needle-free injector induces a non-inferior immune response compared to intramuscular injection of a full dose, in infants and toddlers.

Intervention
All volunteers are bled at day of first injection and receive:
Group 1: intramuscular injection with needle 0.25 mL influenza vaccine
Group 2: intramuscular injection with needle 0.1 mL influenza vaccine
Group 3: intradermal injection jet injector 0.1 mL influenza vaccine
All volunteers are bled 28 days after first injection and receive:
Group 1: intramuscular injection with needle 0.25 mL influenza vaccine
Group 2: intramuscular injection with needle 0.1 mL influenza vaccine
Group 3: intradermal injection jet injector 0.1 mL influenza vaccine
All volunteers bled 56 days afer first injection and receive:
Groups 2 and 3 (those who received only 0.1 mL doses) receive intramuscular injection of 0.25 mL influenza vaccine.
