HPV vaccines are a group of vaccines have been developed to protect again human papillomavirus infection, which may lead to certain types of cancers. HPV refers to a very large group of viruses, and some of these, including HPV 16 and HPV 18, cause cervical cancer, anal cancer, genital warts, and other serious illness.[1]

Available vaccines protect against either two, four, or nine types of HPV.[2][3] All vaccines protect against at least HPV type 16 and 18 that cause the greatest risk of cervical cancer.[3]

Types[edit | edit source]

A number of different vaccines are in use, with bivalent vaccines protecting against two types of HPV, and quadrivalent vaccines protecting against four types of HPV:

  • Bivalent: Ceravix which protects against HPV 16 and HPV 18 only, and contains aluminum hydroxide and monophosphoryl lipid[2]
  • Quadrivalent: Gardasil which protects against HPV 6 and 11, plus HPV 16 and 18, and contains amorphous aluminum hydroxyphosphate sulfate. This is the vaccine currently used in the UK.[4][5]
  • Nonavalent: Gardasil-9, which protects against 9 types of HPV: HPV 6 and 11, HPV 16 and 18, plus HPV 31, HPV 33, HPV 45, HPV 52, and HPV 58, and contains a larger amount of aluminum hydroxyphosphate sulfate and more than twice as many virus-like particles than the quadrivalent vaccine.[6][7] Gardasil-9 was approved for use in the United States in 2014.[7]

Controversy[edit | edit source]

  • Should Your Child Get the HPV Vaccine?[8]
  • 2012, The HPV Vaccine Controversy[9]
  • 2014, Pros, cons, and ethics of HPV vaccine in teens—Why such controversy?[10]
  • Gøtzsche et al. (2021) criticized the European Medicines Agency report on HPV vaccine safety for being overly confident and relying too heavily on data on serious adverse events reported by the manufacturers during clinical trials, and also made criticisms of the Cochrane review process. They referred to previous investigations into rates of raised particular concerns about rates of POTS, ME/CFS and Chronic Regional Pain Syndrome (CRPS) after HPV vaccination, and to rates of post-vaccination in POTS compared to POTS rates after other vaccines. However, Gøtzsche et al avoided stating that the HPV vaccines were not safe and they present any analysis of data, or draw their own conclusions about the HPV vaccines.[11]

ME/CFS[edit | edit source]

The recent use of different HPV vaccines has led to a number of studies looking at HPV vaccine safety, including whether any of the HPV vaccines may increase the risk of developing ME/CFS.[1]

Feiring et al. (2007) conducted a national study in Norway covering six birth cohorts, and found that ME/CFS was not associated with HPV vaccination in girls, but medical history was associated with a higher number of girls developing ME/CFS within two years of HPV vaccine, and lower uptake of HPV vaccination.[6] They commented that ages 10-19 and 30-39 had the highest incidence of ME/CFS.

postural orthostatic tachycardia syndrome (POTS) - A form of orthostatic intolerance where the cardinal symptom is excessive tachycardia due to changing position (e.g. from lying down to sitting up).

tachycardia An unusually rapid heart beat. Can be caused by exercise or illness. A symptom of postural orthostatic tachycardia syndrome (POTS). (Learn more: www.heart.org)

myalgic encephalomyelitis (ME) - A disease often marked by neurological symptoms, but fatigue is sometimes a symptom as well. Some diagnostic criteria distinguish it from chronic fatigue syndrome, while other diagnostic criteria consider it to be a synonym for chronic fatigue syndrome. A defining characteristic of ME is post-exertional malaise (PEM), or post-exertional neuroimmune exhaustion (PENE), which is a notable exacerbation of symptoms brought on by small exertions. PEM can last for days or weeks. Symptoms can include cognitive impairments, muscle pain (myalgia), trouble remaining upright (orthostatic intolerance), sleep abnormalities, and gastro-intestinal impairments, among others. An estimated 25% of those suffering from ME are housebound or bedbound. The World Health Organization (WHO) classifies ME as a neurological disease.

adverse reaction Any unintended or unwanted response to a treatment, whether in a clinical trial or licensed treatment. May be minor or serious.
