Gardasil Vaccine

1. Product Introduction

Gardasil Vaccine is a recombinant vaccine designed to protect against Human Papillomavirus (HPV) types 6, 11, 16, and 18. These four types are responsible for the majority of HPV-related diseases, including cervical cancer, genital warts, and other cancers such as anal, vulvar, and vaginal cancers. Gardasil is a quadrivalent vaccine, meaning it protects against four different strains of HPV.

Manufactured using recombinant DNA technology, the vaccine does not contain live virus and cannot cause HPV infection. It is administered as an intramuscular injection, typically in a series of two or three doses, depending on the recipient’s age. The vaccine is most effective when given before exposure to the virus, usually before the onset of sexual activity.

Gardasil is a globally recognized and widely recommended vaccine by major health organizations including WHO (World Health Organization) and CDC (Centers for Disease Control and Prevention) for the prevention of HPV-related diseases.

2. Uses of This Medicine

Gardasil Vaccine is used for immunization against specific types of HPV. The main uses include:

• Prevention of Cervical Cancer: Caused primarily by HPV types 16 and 18.

• Prevention of Genital Warts: Typically caused by HPV types 6 and 11.

• Prevention of Other HPV-Related Cancers: Including vulvar, vaginal, anal, and oropharyngeal cancers.

• Protection Against Precancerous Lesions: Such as cervical intraepithelial neoplasia (CIN), vulvar intraepithelial neoplasia (VIN), and anal intraepithelial neoplasia (AIN).

The vaccine is approved for use in both males and females, usually starting from age 9 up to 45 years, depending on national guidelines.
