Marketing authorization of the vaccine in the European Union is based on evidence from two Phase III clinical trials: Renoir and Matisse. The first of these is a global, randomized, double-blind, placebo-controlled study designed to evaluate the efficacy, immunogenicity and safety of a single dose of vaccine in adults 60 years of age and older. On its part, MATISSE is a global, randomized, double-blind, placebo-controlled study designed to evaluate the efficacy, safety and immunogenicity of RSVpreF. lower respiratory tract disease (LRTD) and RSV-related severe LRTD in infants born to healthy individuals vaccinated during pregnancy.

There is more danger. conditions.
