Frequently asked questions about HPV

The HPV vaccine has been used for over a decade now, and studies show that protection should last several decades and remain very strong. Research is ongoing to confirm if protection is lifelong, but there is currently no indication that a booster dose is needed (X,X).

In Quebec, HPV vaccination is free for everyone up to age 20 (X).
Men 26 years old or younger who have or plan to have sex with other men are also eligible for free vaccination (X).

People aged 21 to 45 can receive the HPV vaccine free of charge in Quebec as of October 2024. However, this temporary program will end soon, and access may vary depending on regional vaccine supplies (X). The vaccine is always free for those aged 21 to 45 that have a weakened immune system (X).

Before 2024, students were scheduled to receive 2 doses of HPV vaccines. One dose of nonavalent (HPV-9) in the 4th year of primary school, and a dose 60 months later (3rd year of secondary school) of bivalent vaccine (HPV-2). Starting in the 2024-2025 school year (so last year), only the first dose of nonavalent (HPV-9) in the 4th year of primary school is recommended. People that are immunocompetent and under 20 years of age are not required to receive additional doses (X). Two doses of HPV-9 at least 6 months apart are recommended for individuals 21 years or older (X).

The HPV vaccine has been used for over a decade now, and studies show that protection should last several decades and remain very strong. Research is ongoing to confirm if protection is lifelong, but there is currently no indication that a booster dose is needed (X,X).

Most symptoms or reactions are benign and do not last long. In most cases (>50%) people will experience pain at the injection site. Less than 50% of people will also experience redness or swelling at the injection site and less than 10% of people will experience itching around the injection site and/or fever (X). Headache, nausea, fatigue, and muscle pain are also possible, but should resolve in a few days (X).

Over 500 million HPV vaccine doses have been given worldwide, and scientific data show no serious or unexpected safety issues. No link has been found between the vaccine and serious illnesses or deaths (X).

There’s no strict age limit for the HPV vaccine. Even if you’ve already been exposed to some HPV types, the vaccine can still protect you against others. And getting even one dose provides some benefit compared to not being vaccinated at all (X). 

That said, in Canada, the nanovalent HPV vaccine is only licensed for (X): 

  • Girls and women ages 9 to 45
  • Boys and men ages 9 to 26

Outside of these age ranges, the vaccine may still offer benefits, but it’s considered “off-label” use because there isn’t enough data from clinical trials in older age groups. If you’re older, talk to your doctor about whether the vaccine is right for you (X,X). 

The vaccine works best when given before becoming sexually active, but even if you’re already sexually active, it can still help reduce your risk of HPV-related diseases (X).

HPV Immunization is free of charge for eligible Quebec individuals. The price can vary depending on the location where you will receive the vaccine (CLSC, clinic, pharmacy).
You can book an appointment on Clic Santé or by calling 1-877-644-4545 Monday to Friday between 8 a.m. and 6 p.m., or on weekends between 8:30 a.m. and 4:30 p.m (X). 

Originally, HPV vaccination programs focused on girls because the main public health goal was to prevent cervical cancer, which is caused by high-risk HPV types in women. Early safety and efficacy studies were also mostly conducted in females. By preventing infection, the HPV vaccine also helps prevent transmission. Hence vaccinating male against HPV also indirectly protects girls and women (X). Plus, over time, evidence showed that HPV can also cause cancers such as anal, penile, and oropharyngeal cancers in all genders (the risk of oropharyngeal cancer is higher in men than in women). As a result, it made sense to expand the policy rationale to include boys as well (X,X,X,X,X,X,X).
