Vaccine credited with HPV virus reduction in Scotland

Without vaccinating boys there is not enough herd immunity. Somehow I feel this report may be rubbish, but on the surface it seems good news. We have made the same mistake as for rubella (German measles) and tried to save money by only vaccinating females.

BBC News reports good news from Scotland 5th April 2017?: Vaccine credited with HPV virus reduction in Scotland

A campaign to vaccinate girls against a cancer-causing sexually transmitted infection has led to a dramatic drop in reported cases.

Researchers have found a 90% fall in levels of the human papilloma virus (HPV) in Scottish women since the vaccine was made available in 2008.

HPV virus types are thought to account for about 90% of cervical cancers.

Scientists hope the drop in HPV cases will lead to a significant drop in future cervical cancer cases.

The researchers, led by senior epidemiologist Dr Kevin Pollock at Health Protection Scotland, said they hoped to see a decrease in new diagnoses within a year.

He told BBC Radio Scotland: “The two HPV types we were vaccinating against – HPV 16 and HPV 18 – cause about 70% to 80% of cervical cancers within Scotland but the vaccine has exceeded our expectations because it appears to have knocked out another three high-risk HPV types which cause about 10% of cervical cancers.

“So we do forecast within the next few years a 90% reduction in cervical cancer within Scotland.”

Researchers compared the cervical screening and vaccination records of women born in 1995, who had been vaccinated as teenagers, with those from unvaccinated women born between 1989 and 1990.

They found just 0.5% of women from the 1995 group tested positive for the virus, compared with 21.4% of women born before 1990.

The study also showed evidence that the vaccine protected against three other high-risk HPV genotypes involved in the development of cervical cancer.

‘Significant impact’

The research will be presented to the Microbiology Society’s annual conference in Edinburgh on Wednesday by Dr Kate Cuschieri, director of the Scottish HPV Reference Lab.

She said: “These new findings indicate that the positive impact of the HPV vaccine may be even greater than we initially thought.

“Collectively, these data demonstrate the significant and continued benefits of the HPV vaccination programme in Scotland, which has achieved a consistent and high uptake of around 90% in 12 to 13-year-old girls.”

Dr Pollock added: “The very high uptake of the HPV vaccine is strongly associated with these massive reductions in high-risk HPV types that are known to cause approximately 90% of cervical cancer in Scottish women.”

He said the virus was also known to cause a number of other cancers, including vulvovaginal, anal and a subset of head and neck cancers.

“These results suggest that this vaccine will also have a significant impact on these cancers in the years ahead”, he said.

The research, which was funded by the Scottish government, looked at samples from more than 20,000 women, making it one of the largest population-based studies on the impact of the vaccine.

There were 388 new cases of cervical cancer in Scotland in 2014.

About Roger Burns - retired GP

I am a retired GP and medical educator. I have supported patient participation throughout my career, and my practice, St Thomas; Surgery, has had a longstanding and active Patient Participation Group (PPG). I support the idea of Community Health Councils, although I feel they should be funded at arms length from government. I have taught GP trainees for 30 years, and been a Programme Director for GP training in Pembrokeshire 20 years. I served on the Pembrokeshire LHG and LHB for a total of 10 years. I completed an MBA in 1996, and I along with most others, never had an exit interview from any job in the NHS! I completed an MBA in 1996, and was a runner up for the Adam Smith prize for economy and efficiency in government in that year. This was owing to a suggestion (St Thomas' Mutual) that practices had incentives for saving by being allowed to buy rationed out services in the following year.
