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.
