The new quadrivalent Human Papillomavirus (HPV) L1 virus-like particle vaccine (types 6, 11, 16, 18) was studied for immunogenicity and reactogenicity in 506 girls and 510 boys (10-15 years of age) and 513 young women (16-23 years of age). Vaccine was administered in the standard schedule of 0, 2, and 6 months.
