The duration of protection of Gardasil is being monitored through different long-term extension studies from clinical trials in a number of countries. The follow-up will continue to reach 10 years.(1)
The current available data show sustained protection against clinical disease irrespective of age or sex.
In the extension study for girls and boys aged 9 to 15 years at first vaccination, protection against vaccine-type HPV diseases is maintained at 6.5 years post-vaccination. The total extension period is planned for 10 years. (1)
In addition, in the extension of a study in women vaccinated at 16-23 years of age, no cases of cervical pre-cancers due to vaccine-type HPV were detected up to approximately 8 years. In the same study, durable protection was statistically demonstrated to about 6 years. The follow-up in this population will continue to reach 14 years. (1)
These studies also show that the immune response persists after a follow-up of 8 years for 9-15-year-old adolescents and 9 years for women 16-23 years old. (1)
As written in the Committee for Medicinal Products for Human Use (CHMP) report, the administration of Gardasil to 9 to 15 years girls and boys was generally well tolerated through 8 years post-vaccination follow-up. (1)
Data from long-term follow-up studies also support the long-term safety of Gardasil in the other populations studied. (1)
The CHMP report concluded that "immunogenicity and effectiveness data from the long-term follow-up of Gardasil studies demonstrate continued protection against HPV 6, 11, 16 and 18 disease." (1)
This significant update comes in addition to the recent improvements of Gardasil product profile, with a new indication to prevent anal cancer and precancerous anal lesions as well as a schedule of 2 doses 6 months apart for the adolescents 9 to 13 years old. (2)
