Official title
Longitudinal Evaluation of Antibody Kinetics Following Administration of a Non-mandatory Marketed Vaccine in the General Population, Real-life Study
Overview
The study would make it possible to document more explicitly the evolution of antibody titers at following a non-public vaccination over a large post-vaccination period in the French population . Analysis of real-life data would enhance knowledge of vaccine response kinetics It would be useful to identify possible early declines requiring doses Similarly, by analyzing antibody kinetics by age, sex, and vaccination status, the would be possible to determine whether there are differences in the immune response between these different sub-groups. In addition, it would provide additional information to assess the real impact of these non-public vaccines in public health and guide vaccine policies.
Interventions
- Biological Blood collection
Collection of blood before and after a non mandatory vaccination
Primary outcome measures
- Quantification of specific serum antibodies (IgM, IgG) at different times before and/or after vaccination by a reference technique such as ELISA. [Time frame: 3 years]
