HPV vaccines have been developed to protect again human papillomavirus infection. HPV refers to a very large group of viruses, and some of these, including HPV 16 and HPV 18, cause cervical cancer or other serious illness.[1] 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]

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.[3][4]
  • 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.[5][6] Gardasil-9 was approved for use in the United States in 2014.[6]

ME/CFS[edit | edit source]

Feiring et al. (2007) conducted a national study in Norway covering 6 birth cohorts, and found that CFS/ME was not associated with HPV vaccination in girls, but medical history was associated with a higher number of girls developing CFS/ME within 2 years of HPV vaccine, and lower uptake of HPV vaccination.[5] They commented that ages 10-19 and 30-39 had the highest incidence of CFS/ME.
