From September 2012, the Department of Health will change the vaccine it uses to protect girls in the UK against cervical cancer.
The Cervarix vaccine has been used since 2008. It protects againsts HPV types 16 and 18, which causes more than 70% of cervical cancers. Later in the year the Gardasil jab will be used which in addition to protecting against types 16 and 18, also protects against types 6 and 11 which cause nearly all genital warts.
Gardasil, manufactured by Sanofi Pasteur, is the most widely used of the two vaccines and have distributed eighty million doses worldwide. The Department of Health estimates 400 deaths a year will be prevented by the vaccination programme.
