HPV Vaccine Safety

How do we know that the Gardasil® vaccine is safe?

The HSE is guided by the recommendations of the National Immunisation Advisory Committee (NIAC) and the World Health Organization (WHO).

All vaccines used by the HSE including Gardasil® are licensed by the Health Products Regulatory Authority (HPRA) and the European Medicines Agency (EMA). These agencies have strict procedures for the licensing and monitoring of all vaccines to ensure their safety and effectiveness.By March 2017, over 227 million doses of Gardasil® have been distributed worldwide, either as part of national immunisation programmes or by private doctors. Gardasil® is currently used in over 25 European countries, the United States, Canada, Australia and New Zealand.

In Ireland 690,000 doses of Gardasil® have been administered and more than 230,000 girls have been fully vaccinated against HPV.

All national and international regulatory bodies have stated HPV vaccines are safe.

The World Health Organization (WHO) Global Advisory Committee for Vaccine Safety (GACVS) has reviewed the evidence on the safety of Gardasil vaccine in 2007, 2008, 2009, 2013, 2014  and 2015. WHO has never reported safety concerns with HPV vaccines.

WHO has again reported in July  2017 that HPV vaccines are considered to be extremely safe.  Further information can be found here  http://www.who.int/vaccine_safety/committee/topics/hpv/en/

The Centers for Disease Control and Prevention (CDC), US, states HPV vaccination is recommended because the benefit of, preventing cancer, far outweigh the risks of possible side effects.

Since the HPV vaccine Gardasil was licensed in Ireland in 2006 the Health Products Regulatory Authority (HPRA) has continually  reported that the majority of the reports received following vaccination  are side effects known to occur with the vaccine.

There is no scientific evidence in Ireland or in any other country that the HPV vaccine causes any long term medical condition.

The Centers for Disease Control and Prevention, US, which monitors vaccine safety in the US, has monitored the safety of the HPV vaccine for over ten years, provides an information leaflet for parents on the safety of Gardasil vaccine, updated in August 2016, available at http://www.cdc.gov/vaccinesafety/pdf/data-summary-hpv-gardasil-vaccine-is-safe.pdf and further  information at http://www.cdc.gov/vaccinesafety/vaccines/hpv/hpv-safety-faqs.html

In January 2017 all 69 US National Cancer Institute NCI-designated Cancer Centers Endorsed HPV Vaccination

“As national leaders in cancer research and clinical care, we are compelled to collectively call upon parents and health care providers to increase vaccination rates so our nation’s children don’t grow up to become cancer patients.

HPV vaccines, like all vaccines (used in the U.S.), have passed extensive safety testing before and after being approved.

The vaccines have a safety profile similar to that of other vaccines approved for adolescents in the U.S.

Internationally, the safety of HPV vaccines has been tested and approved by the World Health Organization’s Global Advisory Committee on Vaccine Safety”.

HPV Vaccine Safety and Effectiveness

Since HPV vaccine was licensed in 2006 research has been conducted all over the world that shows that the vaccine is safe and prevents cancer. The evidence has been steadily growing since 2006 and now an enormous bank of research exists which proves the safety and effectiveness of this vaccine.
