Adolescent Immunization as part of a Life Course Approach:
Goals and experiences
Immunization in the Context of Adolescent Health
Dubai, 22-23 Oct 2017
Paul Bloem, Expanded Programme of Immunization/IVBWorld Health Organization
Overview
• Adolescent immunization, integration and life course approach - WHO policies
• Global practise in vaccinating adolescents & integration
• A zoom on HPV vaccines
• Country Examples of Adolescent Immunisation Programmes
• Challenges and way forward
Why is adolescent vaccination important?
1. Adolescence represents a critical phase of development between childhood and adulthood
2. Adolescents (10-19) in many LMIC represent up to 25% of the population
3. The health system has very limited interaction with this age group! Vaccination can be a key opportunity

Country examples of adolescent immunization
Mexico: Home-based records across the life course
Case study HPV vaccination in New ZealandIntegrating school based programmes with general practice
• All New Zealand districts offer HPV as a school based programme, as well as in general practice
• Improved connection between school based programmes and GPs – GPs now recall incompletely immunised individuals at age 14
• Reminder Poster developed for GP practices
• Change HPV from grade 7 to Grade 6 to coincide with Tdap vaccination (co-delivery)
(HPV @ 13 years)
Malaysia: HPV vaccine as part of a school health package
South Africa: Integrated school health programmes includes HPV
• New integrated school health policy launched in 2012
• Package of services is provided according to age (grouped into educational phases)
– HIV Counseling and Testing and access to contraception required enabling legislation
• School activity booklet with health messages for girls and boys is delivered with HPV
• De-worming medication to be introduced in 2016 and administered by teachers whilst nurses are vaccinating at the school

Consent• For infants, presence of mother at
the clinic is implied consent
• Redefine the consent process for
vaccinating adolescents not in parents' presence
Social mobilization even more important • Inform both caregivers and adolescents (and teachers and
stakeholders…)
• Non traditional stakeholders (eg .OBGYN)
• Vaccines targeting only girls predisposes to rumours (TT, HPV)
Challenges with vaccination of adolescents
Choice of strategy (Effort and cost considerations)• Health facilities or school-based?
• Community outreaches, Campaigns (eg. Child Health days)
• Balance of cost and coverage
• Coordination with the education and other sectors
How to reach vulnerable populations?• Out-of-school (non-enrolled/absent), Institutionalized, migrant,
farming communities
Reporting and monitoring of vaccination coverage• Challenge of denominators for this new age group
• Grade based/wide age range
Challenges with vaccination of adolescents
The way forward
Ever more vaccines target adolescents and school aged children. This holds potential to develop an adolescent vaccination "platform"
Adolescent vaccination can be integrated in and reinforce school health or adolescent health
Raise awareness and improve vaccination status through School-entry screening or medical check–up's (eg 12 yr old check up)
