Immunization Services
DR. KANUPRIYA CHATURVEDI DR .S.K. CHATURVEDI
Objectives
• Describe what comprises routine immunization services
– Components – Activities within components – Role of a Plan of Action
What is “routine immunization”
• No standard definition
– Hard to define – Means different things to different people – Regional and agency differences
• The sum of human and logistical activities/events to ensure the regular delivery & uptake of vaccines & the monitoring of their positive & adverse impact
What is “routine immunization”
• Implies the “regular” delivery, i.e., known schedule, of EPI vaccines
– Fixed posts &/or outreach
• Part of a larger plan • Not time limited • Goal to provide needed vaccines to all eligible persons and to successive birth cohorts
Routine services: Ensuring that all children receive the WHO recommended vaccination schedule

WHO’s Approach: Components of routine immunization systems
Vaccine Supply & Quality
Logistics
Service delivery
Advocacy & Communication
Surveillance
Components glued together by:
• • • • • • Planning Management Coordination Supervision Training Financing
Components & “glue” exist at national, provincial, district & local level…. Cascading effect
Activities…………….. Vaccine Supply & National level ..Policy on Quality
•Procurement •Quality •Local production •National Regulatory Authority •Strategies for international procurement •Timely vaccine ordering •Financial security for purchase •Supply planning (VVMs, vaccines, syringes)
Lower Levels ..Ordering & supply planning ..Getting vaccine & supplies to the lower levels for administration
Activities………
National Level .Policy statement & implementation • Injection safety • Health care waste disposal • Cold chain • National central cold store • Vaccine/supply management • Transport management •Supplies, supervision
•Lower levels • Vaccine/supply management • Cold chain •Transport • Getting the vaccine to the people
Logistics
Activities…….
National level •Policy •Standards & guidelines •Case definitions •Disease, coverage, adverse events monitoring for nation •Data management systems •Improving data quality •Laboratory Services
Surveillance
Local level •Disease, adverse events monitoring •Vaccine supply •Vaccination info management •Register •Tally sheets
Activities…….
Types of surveillance in EPI •Routine •Generally passive, provides idea on trends, impact of program •Special routine – AFP, fever/rash •Sentinel •Complements weak routine for key diseases •Early warning for outbreaks •Special Surveys •Set baseline disease burden
Surveillance
Activities………
National Level •Technical documents & guidelines •Capacity building •Partnerships with media •Social Mobilization
Local Level •Partnerships with the community •Social Mobilization
Advocacy & Communication
Activities…………
National Level • Supporting local level
Local level • Vaccination activities
Service delivery
Activities…………
Delivery modes - Fixed sites - Outreach - Mobile services - Pulse campaigns - Campaigns
Service delivery
Each mode has its own advantages & disadvantages, its own indications for use, $$ considerations No single mode is appropriate for all circumstances/diseases
The “glue”
5 key components of EPI 1. Planning 2. Management 3. Coordination 4. Supervision 5. Training 6. Financing
Activities to get the job done
National
provincial
district
health facility
Monitoring Program Performance
• Key indicators (an example)
– Coverage levels
• Fully vaccinated child, individual antigens
– Access to services
• BCG and/or DTP1 coverage
– Tracking & follow up activities
• Dropout - DTP1 to Measles • Median age of receipt of vaccines
– Missed opportunities – Cold chain quality
• Vaccines at correct temperature
– Provider knowledge/practices
Plans of Action (POA)
5 key components of EPI 1. Planning 2. Management 3. Coordination 4. Supervision 5. Training
POAs.. ..Detailed & costed activities to ensure adequate implementation of key components and the “glue” … 5 year & 1 year plan … National, provincial, district level plans Must be a living document used to monitor routine immunization services
Plans of Action
• Different formats in different countries, regions • Should contain
– For each component
• • • • • Goals/objectives Key activities Timeline Cost Responsibility
– For each type of glue
• Key activities • Timeline • Cost
District Plans of Action
• Important for efficient service delivery • Similar to national, but with emphasis on
– – – – – – High risk areas High risk populations Special activities, e.g., outreach, mobile services Social promotion Supervision Local funding – sources and channels
Inter-agency Coordinating Committee (ICC)
• Composition
– Example: MOH, WHO, UNICEF, USAID, Rotary, NGOs, etc – Varies by country
• Promotes collaboration & cooperation
• Prevents
– Duplication of activities – Ensures that all activities/components/”glue” are covered and will be addressed in the POA
