About the HPV Vaccine

A vaccine is a substance that improves immunity (protection) to a particular disease. The HPV vaccine protects against the HPV virus which can cause cancer and genital warts in both women and men.

HPV vaccine prevents Cervical Cancer

In September 2020 a study from Sweden reported that Swedish girls and women aged 10 to 30 years old, who had been vaccinated with Gardasil (which protects against 7 out of 10 cervical cancers) resulted in a big reduction in the risk of invasive cervical cancer in the population.

In the study cervical cancer was diagnosed in 538 women who had not received Gardasil vaccine and in only 19 women who had received the vaccine.

In Ireland, Gardasil 9 vaccine given through the school imminisation programme protects against 9 out of 10 cervical cancers.

How we know the HPV vaccine is safe

The HPV vaccine is safe. The safety of the HPV vaccine has been studied for over 15 years. Over 1 million people have been studied during clinical trials since the vaccine was licensed in 2006. We have over 100 pieces of research about HPV vaccine safety and effectiveness.

No country has raised concerns about the safety of the HPV vaccine. There is no scientific evidence in Ireland or in any other country that the HPV vaccine causes any long-term medical condition.

Vaccines are strictly monitored and reviewed regularly by international bodies including the:

Gardasil 9

The HPV vaccine currently used in Ireland is called Gardasil 9. Over 100 million people have been fully vaccinated with Gardasil worldwide. This includes over 350,000 people in Ireland.

HPV vaccine side effects

Long-term side effects

All international bodies have continually reported that the vaccines used in Ireland have no long-term side effects.

Short-term side effects

Most people have no problems after the vaccine. The HPV vaccine has many of the same, mild side effects as other vaccines. 

Some people have an area of soreness, swelling and redness in their arm where the injection was given. This is nothing to worry about as this usually passes after a day or two.

Some people may get a headache, or feel sick in their tummy or have a slight temperature. If this happens, paracetamol or ibuprofen will help.

Occasionally, some people may feel unwell and faint after getting their injection. To prevent this, when someone gets the vaccine they are asked to sit down and rest for 15 minutes after the vaccination.

Severe allergic reactions to vaccines are very rare. School vaccination teams are trained to treat any severe allergic reaction. If you are worried, talk to a member of the school team or your GP.

False claims about the HPV vaccine

We are aware of stories on social media claiming that the HPV vaccine causes an increase in cases of:

  • postural orthostatic tachycardia syndrome (POTS) – an increase in heart rate that can make you feel faint and dizzy
  • complex regional pain syndrome (CRPS) – a form of chronic pain that usually affects an arm or a leg

The European Medicines Agency (EMA) researched these claims in 2015. They found no evidence that the HPV vaccine leads to an increase in these conditions.

The HPV vaccine in other countries

Over 120 countries now have a HPV vaccine programme, with more than 30 of these countries giving the vaccine to boys and girls.

These countries include:

  • Australia
  • Italy
  • New Zealand
  • Norway
  • US
  • UK

HPV vaccine effectiveness

The HPV vaccine now protects against the types of HPV that cause 9 out of 10 cervical cancers.

A study from Sweden published in 2020 showed that vaccination with HPV vaccine is associated with a big reduction in the risk of cervical cancer. 

The HPV vaccine has greatly reduced cases of pre-cancers of the cervix in young women in many countries including Australia, Sweden, the US and the UK.

In countries where the HPV vaccine is used, the number of cases of genital warts has decreased dramatically in both young women and men.

Since the HPV vaccine was licensed in 2006, research has been done all over the world. It shows that the vaccine is safe and prevents cancer. Read more about HPV vaccine safety and effectiveness.

The World Health Organization (WHO) considers the HPV vaccine to be extremely safe. Read more about the safety of the HPV vaccine on the WHO's website.

Patient information leaflet 

The vaccine used as part of the school immunisation programme is called Gardasil 9. It is produced by MSD Ireland (Human Health). 

Read the patient information leaflet (PIL) for Gardasil 9 (PDF, 233KB, 6 pages).

HPV screening

HPV screening for females

Even if you have had the HPV vaccine, you should have your cervical screening test (smear test) each time it's due. This is because the HPV vaccine doesn't give complete protection against cervical cancer.

Read more about when you should have a cervical screening test.

HPV screening for males

There is no HPV screening currently available for males. The HPV vaccine is your best chance at protecting yourself against genital warts and HPV-related cancers.

The HSE School Vaccination Programme

The HPV vaccine, along with MenACWY and Tdap, is given to first year students in secondary school by our school vaccination teams. 

It is hoped that the second level school programme will commence from the 27th September 2021.

The HSE school vaccination programme may need to take place in a different venue from the school premises or may still be delayed because of COVID-19. The HSE will try to keep these changes to a minimum.

The HSE school vaccination programme may need to be done in a different venue or may be delayed because of COVID-19.

There is no requirement to restart the HPV vaccine schedule if the schedule is interrupted because of COVID-19. The National Immunisation Advisory Committee (NIAC) advice from the Immunisation Guidelines for Ireland says:

If an immunisation course is interrupted, it should be resumed as soon as possible. It is not necessary to repeat the course, regardless of the time interval from the previous incomplete course*. The course should be completed with the same brand of vaccine if possible.
