About HPV
Human papillomavirus (HPV ) is a very common virus, with more than 100 strains worldwide. It can cause cancer in the cervix, vagina, vulva, penis, anus, mouth and throat, as well as genital warts.
The HPV vaccine helps protect against these cancers and genital warts caused by nine types of the virus (6, 11, 16, 18, 31, 33, 45, 52 and 58).
Spreading HPV
HPV spreads through intimate skin-to-skin contact.
Seventy-five per cent of Canadians will get an HPV infection at some time in their lives. Most people will not know that they are infected or that they are passing the virus on to someone else.
Symptoms
Most people infected with HPV do not develop symptoms. Cervical cancer and other HPV-related cancers might not have signs or symptoms until they are advanced and hard to treat. That is why it is important for people to get regular health exams.
Getting the vaccine
Students should get the HPV vaccine because it is:
- Effective: It can prevent almost 100 per cent of some cervical cancers. The vaccine can prevent 90 per cent of genital warts.
- Age appropriate: Teenagers are more likely to try activities that increase the risk of infection. This is why it is important that youth get the vaccine before this stage.
Who should not get this vaccine
Students should see their doctor for possible vaccination if they have:
- a history of a bad reaction after getting a vaccine
- an allergy to yeast protein
Deciding not to vaccinate
The HPV vaccine is not required by law to attend school. However, your student could be at risk of getting warts or cancer caused by HPV if you decide not to vaccinate.

Preparing your child for vaccination
Before vaccinating your child:
- Talk to your student about the vaccine.
- Complete and return the consent form.
- Review helpful ways to deal with fear or anxiety (for example, count to ten, look away from needle, focus on breathing).
On clinic day, make sure that your child:
- has something to eat
- wears a short sleeve shirt
Doses
The vaccine is usually given in 2 injections, at least 6 months apart. Some people (for example, older students or people with weakened immune systems) might get 3 injections over 6 months. You need all doses to get full protection.
Safety of vaccine
The HPV vaccine is very safe and effective. It was carefully tested and evaluated before receiving approval by Health Canada.
