Competing Interests

Clotilde El-Guerche Séblain is an employee of Sanofi Pasteur. She helped define the study objectives, was involved in the discussion on the interpretation of the results, critically revised the manuscript and approved its final version. However, she had no access to the study database, did not conduct any statistical analysis, and had no power to decide what results should be published and in what form, nor to what journal submit the manuscript. Importantly, when reviewing the manuscript, her revisions concerned the epidemiological findings and not the public health conclusions. All the other authors declare they have no conflict of interests to disclose.
