HPV Vaccine

The Human Papillomavirus (HPV) vaccine is a vaccine designed to protect against certain types of cancer-causing viruses, specifically those that cause cervical, anal, oropharyngeal, penile, vulvar, and vaginal cancers.

Types of HPV Vaccines

There are three types of HPV vaccines available:

• Gardasil (Quadrivalent): protects against four types of HPV (6, 11, 16, and 18)
• Cervarix (Bivalent): protects against two types of HPV (16 and 18)
• Gardasil 9 (Nonavalent): protects against nine types of HPV (6, 11, 16, 18, 31, 33, 45, 52, and 58)

Administration

The HPV vaccine is typically administered in a series of two or three doses, depending on the age of the recipient and the type of vaccine. The Centers for Disease Control and Prevention (CDC) recommends:

• Two doses for children aged 11-12 years, with the second dose given 6-12 months after the first
• Three doses for individuals who start the series at age 15 or older, or for those with certain immunocompromising conditions

Benefits and Effectiveness

The HPV vaccine has been shown to be highly effective in preventing:

• Cervical cancer: up to 90% reduction in risk
• Genital warts: up to 90% reduction in risk
• Anal, oropharyngeal, penile, vulvar, and vaginal cancers: significant reduction in risk

Safety and Side Effects

The HPV vaccine is generally safe and well-tolerated. Common side effects include:

• Pain, redness, or swelling at the injection site
