Vaccine Information Leaflet
HPV vaccines help to prevent infection with Human Papillomavirus (HPV), which may lead to cervical, vaginal and vulvar cancer in women, or anal cancer and genital warts in both women and men.
HPV infection spreads from one person to another through skin-to-skin contact such as during sexual activity, or less frequently during delivery from an infected mother to her baby.
Most HPV infections, including the strains that can cause cervical cancer, do not have any signs or symptoms. Symptoms of cervical cancer may include abnormal vaginal bleeding such as bleeding after menstrual periods or after sex. There may also be changes in the amount, colour or smell of vaginal discharge. It is recommended to have regular screening, e.g. Pap smear to detect cervical cancer early.
There are two types of HPV vaccines available in Singapore. They are the HPV2 (Cervarix), and HPV9 (Gardasil 9). Cervarix provides protection against HPV types 16 and 18, which account for 70% of all cervical cancers, and have been shown to be both clinically- and cost-effective in the local setting. It is registered for use in females. Gardasil 9 provides protection against an additional 20% of cancer-causing HPV types. It is registered for use in both females and males.
The Singapore National Childhood Immunisation Schedule (NCIS) and National Adult Immunisation Schedule (NAIS) recommend that all females should receive the vaccine between the ages of 9 – 26. For those under 15, there is a total of 2 doses and for those 15 and above it is a total of 3 doses (at intervals of 0, 1-2 months and 6 months). Although not included in the NCIS and NAIS for males, some HPV vaccines are licensed for use in males to protect them from being infected and spreading the HPV virus.
