HPV vaccination is effective in the prevention of high grade cervical lesions and is now recommended for all females aged 9-26 years by the Canadian National Advisory Committee on Immunization (NACI) [3]. Although the vaccine is licensed for females, males can also develop anogenital warts and can transmit the virus to their partners. Immunogenicity trials have shown similar response to vaccine in adolescent males compared to females [15]. In addition, if women have been infected with 1-3 out of the four serotypes, vaccination appears to prevent cervical lesions from the remaining serotypes [16]. Therefore, although the vaccine is licensed for women ≤ 26 years old, it may also be applicable to somewhat older women who may not have acquired all four serotypes.
