Cases of invasive pneumococcal disease in children reduced

The number of cases of invasive pneumococcal disease (IPD) in children has fallen since the introduction of a new vaccine a year ago.

Modelling data reveals cost effectiveness of HPV vaccine

New modelling research presented at the Health Protection Agency's annual conference will show that up to 70% of cases of cervical cancer and 95% of cases of genital warts in men and women could be prevented by the introduction of human papilloma virus (HPV) vaccination into the UK 's national immunisation programme. This is in addition to the cancer cases already prevented by the NHS cervical screening programme.
