HPV vaccine

5-minute read

Human papillomavirus (HPV) is a very common virus that is spread through sexual contact. HPV causes most cases of cervical cancer and genital warts, but you can be vaccinated against it.

What is HPV?

HPV is a sexually transmitted virus that can affect any male or female who is sexually active, even if they only experience sexual contact once. Nine out of 10 people have HPV at some time in their lives.

There are many different types of HPV virus; some are considered 'low risk' while others are 'high risk'. Low-risk HPV types can cause genital warts and don't cause cancer.

High-risk types of HPV can cause cervical cancer or other cancers, including:

  • anal cancer
  • vaginal cancer
  • cancer of the vulva
  • cancer of the penis
  • oropharyngeal cancers (cancers of the back of the throat, including the base of the tongue and tonsils)

What are the symptoms of HPV?

Most people infected HPV have no symptoms. Some types of HPV can cause genital warts, which are small growths on or around your genitals and anus.

If you are infected with a type of HPV that causes cancer, the virus can cause changes to the cervical cells, which can eventually lead to cancer. There are usually no symptoms, but some people may notice:

If you notice any of these symptoms, see your doctor.

How does HPV spread?

HPV is spread through genital to skin contact during sexual activity through tiny breaks in the skin. The virus can live in the skin for many years. It spread to another person even if there are no visible genital warts.

How is HPV diagnosed?

Diagnosis of HPV is usually made by checking symptoms, examination and, for women, doing a Cervical Screening Test. This test, which replaced the Pap smear, can detect high-risk HPV. There is no blood test to detect HPV.

How is HPV treated?

There is no treatment for HPV. The body usually gets rid of the virus by itself over time, which can take about a year. You will probably need to be re-tested to see if the virus has gone.

If you develop genital warts, your doctor may 'freeze' them off (cryotherapy) or suggest an ointment or cream. Sometimes genital warts need to be removed in hospital.

Cervical and other cancers need to be treated by specialists. Your doctor will advise you on the treatments you need.

Can HPV be prevented?

Exposure to HPV can occur through genital-to-skin contact. Using condoms offers some protection, but you can still catch HPV because condoms don't cover the whole genital area.

The best way to protect yourself and others against HPV is to be vaccinated. In women, the vaccine protects against 9 types of HPV that cause cervical cancer; it does not protect against all types of HPV. It also helps protect against genital warts and some types of vaginal, vulval and anal cancers.

In men, HPV vaccination helps protect against genital warts and some anal, penile and throat cancers.

The HPV vaccine is recommended for:

  • adolescents aged 9 to 18 years
  • people who have weakened immune systems
  • men who have sex with men

The best time to be immunised is before you are sexually active. Boys and girls aged 12 to 13 receive the free HPV vaccine at school on the National Immunisation Program Schedule. It's also available for free to anyone under 20 if they weren't vaccinated at school.

You can still be vaccinated if you have been infected with a type of HPV in the past.

Women who have received the HPV vaccine should still have regular cervical screening tests, since the vaccine doesn't cover all types of HPV. Women aged 25 to 70 need to be screened every 5 years, or 2 years after their last Pap smear.

Who shouldn't get the HPV vaccine?

The vaccine isn't suitable for people with certain bleeding disorders or a yeast allergy, or for pregnant women (although research shows there will be no significant effect on you or your baby if you have the vaccine and later find out you are pregnant). Ask your doctor if you're not sure whether you should be vaccinated against HPV.

HPV vaccine

Vaccination is your best protection against HPV. This table explains how the vaccine is given, who should get it, and whether it is on the National Immunisation Program Schedule. Some diseases can be prevented with different vaccines, so talk to your doctor about which one is appropriate for you.

What age is it recommended? 9 to 18 years.
How many doses are required?

2 if aged 9 to 14 years.

3 if starting HPV vaccination at over 15 years of age, or if there are problems with your immune system.

How is it administered? Injection
Is it free?

Free for children aged approximately 12 to 13 years (at school).

For everyone else, there is a cost for this vaccine.

Find out more on the Department of Health website and the National Immunisation Program Schedule, and ask your doctor if you are eligible for additional free vaccines based on your situation or location.

Common side effects The vaccine is very safe. Common side effects include pain, redness and swelling where the needle went in, headache, tiredness, body aches and fever.
