Vaccination is up to 90% effective at preventing the HPV types responsible for most genital warts and HPV-related cancers.
The latest 9-valent vaccine protects against the nine HPV types that are known to cause approximately 90% of cervical cancers, 80% of cervical pre-cancers, 75% of HPV-related vulvar, vaginal and anal cancers and pre-cancers, and over 90% of genital warts.
Numerous scientific studies and clinical trials were done to ensure that HPV vaccines are safe. People who were subjects of the studies had very few serious side effects. The most common is temporary soreness at the site of injection. In some cases, HPV vaccination is not recommended, such as in the case of women who are pregnant or breastfeeding or people who have certain blood conditions or an immune disorder.
In Alberta Gardasil is free for females age 9 to 45 and males ages 9 to 26. Three doses are required. If you are not eligible for the vaccine it may be covered under your insurance.
