Gardasil vaccine packets. Gardasil was the world's first commercially available vaccine against diseases caused by the human papillomavirus (HPV). HPV causes a number of cancers,including cervical and penile cancers,and genital warts. The vaccine works by using inactive virus particles,which trigger an immune response without causing any illness. Once the immune system has been exposed to the vaccine,it will be better prepared to prevent infection by the active virus. This vaccine,developed by US company Merck and French company Sanofi Pasteur,was approved for use in 2006 | |
