A jab which protects against cervical cancer could save more lives than previously thought, research suggested today.
The vaccine is given to young girls to guard against sexually transmitted human papillomavirus (HPV), which causes most cases of the disease.
Previous research suggested that HPV caused 70pc of cases of cervical cancer, the disease that killed reality TV star Jade Goody.
Now, however, experts believe the jab could prevent as many as 77pc of cases, and could offer cross protection to other strains of HPV.
The latest research, published in the British Journal of Cancer, was carried out by scientists at the Health Protection Agency (HPA), the University of Manchester and Manchester Royal Infirmary.
Their study involved analysing which types of HPV women had, taken from more than 6,000 samples.
