Cervical Cancer Vaccine – The Facts
It is now generally accepted that better than 99% of all cervical cancers are caused by a viral infection, the Human Papillomavirus (HPV(G)). This virus is usually, though not exclusively, transmitted between partners during sexual intercourse. There are over 60 strains of HPV which can cause various medical conditions; however two strains, HPV16 and HPV18 are known to cause over 70% of cervical cancers.
