U.S., Sept. 18 -- ClinicalTrials.gov registry received information related to the study (NCT07824310) titled 'Immunogenicity and Safety of HPV-4 Vaccine With or Without Td Vaccine in Children' on Sept. 11.

Brief Summary: This study will evaluate the safety and immune response of a single dose of a quadrivalent human papillomavirus (HPV) vaccine when given together with a tetanus-diphtheria (Td) vaccine in healthy children and adolescents aged 9 to 15 years.
