New HPV 9 Vaccine Provides Wider Protection


 

HPV or Human Papillomavirus is a common sexually transmitted viral infection. Though certain types of the virus are harmless and resolve by themselves, some may lead to genital warts and cervical cancer.

 

Two Categories of HPV: Low-risk and High-risk

Human Papillomavirus or HPV is a common viral infection transmitted through skin-to-skin contact during sexual activity or by sharing contaminated sex toys. It can affect both men and women and is categorized into high-risk (oncogenic) types that cause cancer and low-risk (non-oncogenic) types that do not cause cancer but cause genital warts.

Low-risk HPV type infection sometimes will resolve by itself and the infected person may not develop any symptoms or health issues. High-risk HPV infection causes:

  • Vagina, vulva, and cervical cancer
  • Penile cancer
  • Anal cancer and throat cancer (including tongue and tonsils)

 

Low-risk HPV types

(Do not cause cancer)

6, 11, 27, 32, 40, 42, 43, 44, 54, 55, 57, 60, 61, 62, 64, 71, 72, 74, 76, 81, 83, 84, 86, 87, 89, 90, 91 6 and 11 are responsible for about 90% of genital warts cases.

Possible-risk HPV types

(Possible to cause cancer)

26, 30, 34, 53, 66, 67, 68, 69, 70, 73, 82, 85, 97

High-risk HPV types

(May cause cancer)

16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59 16 and 18 account for about 70% of cervical cancer cases.

 

Who Is at Risk of Getting HPV Infection?

HPV is a common viral infection, that may not manifest within months or years after a person was first infected. There are many people who have it and do not know when they first come in contact with the virus. This means an infected person who has no signs or symptoms of infection, can pass it to others.

However, the risk of infection seems higher in people who have multiple sexual partners and those who have an already weak immune system such as patients with Human Immunodeficiency Virus (HIV) or are taking immune-system suppressing drugs.

 

Types of HPV Vaccines

At present, there are two types of vaccines approved in Singapore, which are the quadrivalent (4 strains) and nine-valent (9 strains) HPV vaccines.

Who Should Get Vaccinated Against HPV?

HPV vaccinations are recommended for both females and males, aged 9 to 26 years old. They are most effective if given before the person starts becoming sexually active.

However, for people who have started having sex, HPV vaccinations can still provide protection from HPV types that they have not yet been exposed to.
