Competing Interests

The authors of this manuscript have the following competing interests: KS and JD have received unconditional grants for other studies from Merck and Sanofi Pasteur Merck Sharp & Dohme; PS has received unconditional grants for other studies and honoraria from GlaxoSmithKline; LAD has received unconditional grants for other studies from GlaxoSmithKline, Merck, and Sanofi Pasteur Merck Sharp & Dohme; Eva Netterlid reports other relationships related to the Swedish HPV Vaccination Register (SVEVAC). SVEVAC, originally developed at the Public Health Agency of Sweden (formerly the Swedish Institute for Communicable Disease Control), is currently funded by the Swedish Association of Local Authorities and Regions. In the start-up phase of the registry, sponsoring was also received from Sanofi Pasteur Merck Sharp & Dohme and GlaxoSmithKline, and for a period a minor part of EN’s salary came from these funds. The authors confirm that the information included in the Competing Interests section does not alter their adherence to PLOS ONE policies on sharing data and materials.
