An AE is any untoward medical occurrence in a clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of a study intervention. AEs such as redness/erythema, swelling, pain, and induration at the injection site are recorded. The percentage of participants who experience 1 or more injection-site AE will be reported.

V503 is an investigational 9-valent human papillomavirus (HPV) vaccine being developed for the prevention of cervical cancers, vulvar cancer, vaginal cancer, genital warts, and other papillomavirus infections. It is currently in Phase 3 clinical development and is not yet approved by regulatory authorities.
V503 is being developed by Merck & Company, Inc., which trades under the ticker symbol MRK. The company is conducting Phase 3 clinical trials to evaluate the vaccine's safety and efficacy in preventing HPV-related diseases.
V503 is in Phase 3 clinical development. It is an investigational vaccine and has not been approved by the FDA or other regulatory agencies. Multiple Phase 3 trials have been completed, and the drug remains under active investigation.
V503 has been studied in several Phase 3 trials, including NCT00943722 in preadolescents and adolescents, NCT01047345 in females previously vaccinated with GARDASIL, NCT01304498 comparing V503 to GARDASIL, and NCT03158220 in adult and young adult women. These trials have enrolled over 5,800 participants.
V503 is a 9-valent human papillomavirus (HPV) L1 virus-like particle (VLP) vaccine. It works by presenting HPV L1 proteins as virus-like particles to the immune system, stimulating an immune response that protects against nine HPV types associated with cervical cancers and genital warts.
V503 is not the same as GARDASIL. While both are HPV vaccines developed by Merck, V503 is a 9-valent vaccine that targets nine HPV types, whereas GARDASIL is a quadrivalent vaccine targeting four types. Clinical trials have directly compared V503 to GARDASIL.
