Cervical cancer vaccines very effective worldwide, study shows
Vaccination against the virus that causes almost all cervical cancer is having a major impact on stopping infections and should significantly reduce cases of the disease within a decade, a new study demonstrates, Reuters reports.
Scientists from Britain and Canada said they found “strong evidence” that vaccination against the human papillomavirus (HPV) works “to prevent cervical cancer in real-world settings”.
Substantial reductions in cervical cancer in the next 10 years
We should be seeing substantial reductions in cervical cancer in the next 10 years”, commented Marc Brisson, a specialist in infectious disease health economics at Canada’s Laval University who co-led the study.
Two HPV types that cause 70% of cervical cancers
Brisson’s team gathered data on 60 million people over eight years from 65 separate studies conducted in 14 countries and pooled it to assess the vaccines’ impact.
They found that the two HPV types that cause 70% of cervical cancers - known as HPV 16 and HPV 18 - were significantly reduced after vaccination, with an 83% decline in infections in girls aged 13 to 19 and 66% drop in women aged 20 to 24 after five to eight years of vaccination.
