The Cervical Cancer Vaccine
● Cervical cancer is caused by certain carcinogenic (cancer causing) types of the
sexually transmitted Human Papillomavirus (HPV）
● Of these types over 70% of women who develop cervical cancer in their 20s and 30s

● The cervical cancer vaccine protects women from being infected with these two
highly carcinogenic types of HPV (HPV 16 and HPV 18)
