NCT ID: NCT03293498

Last Updated: 2022-12-21

Results Overview

The immunogenicity of Tri-NIV at 2 different doses, and the licensed comparator Fluzone HD (Sanofi Pasteur), in healthy older adults ≥ 60 years of age, based on hemagglutination inhibition (HAI) responses to vaccine-homologous influenza A and B strains, as recommended for the 2017 - 18 Northern hemisphere vaccine, at Day 21 post-dosing expressed as GMR.

Participant Flow

Participants took part in a study conducted at 3 different clinical sites from September 18, 2017 to October 29, 2018.

Healthy older adults (≥ 60 years of age) were enrolled in the study and divided into 3 treatment groups based on gender, age, and history of 2016-17 influenza vaccine. Participants were treated with different doses of Tri-NIV Vaccine (0.3 mL,0.8mL), Fluzone HD (0.8 mL), and Placebo (0.5 mL) as Intramuscular (IM) injection into the deltoid muscle.
