The current cervical cancer jab, Cervarix is to be replaced by Gardasil. The jab is given to girls aged 12 and 13 and protects against strains of human papillomavirus (HPV). HPV is a sexually transmitted infection which is the cause of many cases of cervical cancer.
More than 5 million doses of Cervarix have been given but it has now been decided to change to Gardasil as this also protects against genital warts.
Doctors believe this is the safer option as there are 100,000 new cases of genital warts in England every year and condoms only prevent transmission by around 50%.
Experts state that changing medications and immunisations is not unusual and those who have been vaccinated using Cervarix need not worry as they are fully protected against HPV.
