Merck Defends Current GARDASIL 9 Dosing Amid Regulatory Discussions on Single-Dose Regimen
- Merck affirmed its position that CDC recommendations should remain consistent with approved GARDASIL 9 labeling until sufficient data enables FDA and European Commission to license alternate dosing regimens.
- The FDA has established high evidentiary standards for single-dose regimen approval, requiring comparable effectiveness data, demonstration of non-reduced efficacy beyond cervical persistent infection, and efficacy data in men.
- GARDASIL 9 currently uses 2-dose regimens for ages 9-14 and 3-dose regimens for ages 15-45, with over 10 years of real-world experience supporting these approved schedules.
- Merck has invested over $2 billion in manufacturing capacity expansion, doubling HPV vaccine supply twice between 2017-2024 to meet global demand across 150+ national immunization programs.
