Other side effects

Some girls may feel dizzy or faint after vaccination. Girls are asked to sit or lie down for the injection and for about 15 minutes afterwards to help reduce the chances of them fainting or hurting themselves falling over.

People have reported other side effects. But because these come from people reporting side effects themselves, rather than controlled clinical tests, it's not possible to say how often they happen or to how many girls.

Other side effects that have been reported include:

  • bruising or bleeding more easily 
  • chills, weakness, tiredness or general feeling unwell
  • swollen glands
  • pain or tenderness in the joints or muscles
  • vomiting
  • fits (seizures)

Most of the symptoms are reported after any kind of vaccination. But if you have any of these or other symptoms, you should talk to the person who gave you your vaccination, a pharmacist, your doctor or a nurse.

If you feel very ill, get medical help straight away.

Reporting side effects

You can also report any side effects you think may be linked to the HPV vaccination using the Yellow Card Scheme, which is run by the Medicines and Healthcare Products Regulatory Agency.

Allergic reactions

Very rarely, some girls may have a more severe allergic reaction, known as an anaphylactic reaction, immediately after HPV vaccination.

Signs of an anaphylactic reaction include:

If a girl has a severe allergic reaction, the healthcare professional giving the vaccine will be fully trained in how to deal with it.

People recover completely with treatment, usually within a few hours.

An anaphylactic reaction can also be caused by other things, such as bee stings and food allergies.

If you're with someone and they start to experience the symptoms of anaphylaxis, dial 999 immediately to request an ambulance.
