PREVENTING HPV :

VACCINE 

HPV Vaccines are made from live-biological products or DNA that is empty protein shells called virus-like particles (VLP). Current HPV vaccines are designed to protect against HPV 16 and 18; the quadrivalent vaccine also protects against low-risk genotypes 6 and 11.

Primary prevention begins with HPV vaccination of girls aged 9-13 years, before they become sexually active.

Other recommended preventive interventions for boys and girls as appropriate are:

  • Warnings about tobacco use, which often starts during adolescence, and which is an important risk factor for cervical and other cancers;
  • Education about safe sexual practices, including delayed start of sexual activity;
  • Promotion and provision of condoms for those already engaged in sexual activity; and
