HPV Immunisation update • Update on the programme • Overview of Surveillance strategy • Details of proposed surveillance linked to the cervical screening programme
HPV immunisation • 3 dose immunisation given at school to girls in secondary S2 (aged 12-13) • Catch-up immunisation for girls up to the age of 17 (including school leavers) • Protects against 2 HR types of HPV that cause ~70% of cervical cancer

Aims for public health surveillance of the HPV programme in Scotland • Evaluate the effect of the immunisation programme on HPV and HPV-related disease • Inform decision making on the future optimum mix of immunisation, screening and HPV testing to reduce cervical cancer in Scotland. • Monitor vaccine failure and adverse events that may be linked to immunisation
Core elements 1. Vaccine uptake 2. Adverse events that may be associated with immunisation 3. Knowledge attitudes and awareness in the vaccination era 4. The impact of the immunisation programme on HPVinfection in the population 5. The impact of the immunisation programme on Cervical Cancer & Precursors (CIN+)
Vaccine uptake • Working closely with ISD • Routinely monitor and publish immunisation uptake rates as for other childhood immunisations
Safety • MHRA yellow card • Post-licensing long term studies • Analysis of UK disease incidence statistics • Register of vaccination in pregnancy
Scotland (December 2007) Method: qualitative interview study to explore the views of a sample of parents, young people (108) and school teachers undertaken in 7 schools in a range of local authority areas Key findings: Low knowledge levels Immunisation programme welcomed Drug safety Some misconceptions Information – clear and honest and in a variety of formats Attitudinal Research
Scotland • Catchup immunisation begins this year (girls in S5-S6 & school leavers aged 16-17)) • Screening begins at age 20 • First immunised cohort invited for screening in 2010
The impact of the immunisation programme on HPVinfection in the population • Baseline information (UK published and Scottish national prevalence study) • Ongoing surveillance of HPV infection and circulating genotypes
Population under surveillanceFemales 20 – 24 years of age – who • are immunised and attend cervical screening • decline immunisation but attend cervicalscreening • are immunised but do not attend cervical screening • are neither immunised nor attend cervical screening
The Cervical Screening population HPV prevalence and subtypes in a sample from the screened population ongoing Monitor abnormal smears, and cervical abnormalities and type specific prevalence for cancer precursors (CIN 2&3) periodic

Cervical screening – uptake by age group Scotland 2001/2 to 2006/7 Source ISD: Uptake for Cervical Screening by Age Group: Scotland 1, 1st April 2001 - 31st March 2007 Percentage uptake of females who had a record of a previous smear taken within last 3.5 years
Surveillance in the non-screened population Options: • Direct survey approach • Testing of residual specimens
Postal Testing Kits – non-attenders • “Teaser” mailing – pre-information + opt-out • Postal Testing Kit arrives • Reminder mailing Issues Low response rate expected Acceptability Ethical issues • giving results • preserving confidentiality • Not an alternative to screening Practical issues – organising the survey

Fundamentals • Surveillance Year – calendar year from Jan 2009 • Overall population • 20-24 yr olds • Females • Not vaccinated and do or do not present for CS • Vaccinated and do or do not present for CS • Timeline – 12 years • 55% of cohort presenting for smears 2006/7 • Minimise use of Personally Identifiable Information (PII)
