The HPV vaccine

HPV (human papillomavirus) is a very common virus. Most people come across it at some point in their lives. Usually the body clears it without any signs at all. But some types of HPV can lead to cervical cancer and other cancers many years later.

The cervix is the lower part of the womb. The vaccine is one of the most effective ways to protect against these viruses.

The vaccine works best when it is given before someone comes into contact with the virus. Your body also responds more strongly at this age. That is why the World Health Organization recommends it for girls aged 9 to 14. It can be given later too, and a doctor can advise you.

It is an injection in the upper arm. A doctor will tell you how many doses you need and where you can get it. The vaccine doesn't contain live virus, so it can't give you the infection.

Side effects are usually mild and pass quickly:

• Pain, redness or swelling on your arm
• Headache or tiredness
• A slight fever

Sitting down for a little while after the injection helps prevent dizziness. Serious side effects are very rare.

You may read online that the vaccine causes infertility. That isn't true. Large studies have found no such link. The vaccine has been monitored for well over a decade and millions of people have had it.

If you have questions, ask a doctor together with a parent.
