Transcript Scaling-up for Measles Eradication Implications for WHO

Global Measles and Rubella:
Highlights, Priorities and Critical
Issues
Global Measles and Rubella Management Meeting
15-17 March, WHO/HQ Geneva
Peter Strebel and Edward Hoekstra
Tenth Anniversary of the Measles Initiative
 Joint Declaration, 31 January 2001
 Work together in partnership to further
reduce measles mortality according to
each partner organization's strengths
 To advocate for human and financial
resources
 Support strategies outlined in the
WHO/UNICEF Strategic Plan, including
use of rubella vaccine
 Support the GAVI goal of saving lives

Highlights
WHA, May 2010
 Report A63/18: "Global Eradication of Measles"
– Summary of global progress
– Requirements for eradication
– Feasibility of elimination in each region
 2015 Global Targets as milestones towards eradication
– Vaccination coverage of 90% national level and 80% in every district
– Reported incidence of <5 cases of measles per million
– Mortality reduction of 95% vs 2000
 Targets aligned with the 2015 Millennium Development
Goal of reducing child mortality by 2/3

Feasibility of Measles Eradication
 July 2010 – Global Consultation
– Measles can and should be
eradicated
– In the context of strengthening
immunization and primary health
care systems
– Opportunity to accelerate rubella
control and the prevention of
congenital rubella syndrome
– Target date of 2020 feasible if
measurable progress
6|
SAGE, November 2010
 Measles can and should be eradicated
 Measurable progress towards 2015 global targets and
existing regional elimination goals is required before
establishing a target date
 Requested frequent updates on progress
 Executive Board (Jan 2011) endorsed SAGE approach

103 million children vaccinated
High quality
State-of-the-art communications
 India starts implementing 2nd
dose
– Phase 1 catch-up campaign
– 25 million children in 13 states
– Good vaccine handling,
injection safety
– Demand low in urban areas
– Weak national level
coordination

Priorities
#1 Gaps Population Immunity
 Increase 1st dose vaccination
coverage
Measles IgM positive results per province:
South Africa, January 2009 -3 March 2011
(N=18,404 lab-confirmed cases)
 High quality SIAs
Mass vaccination campaign (week 15-18)
800
 Introduce routine 2nd dose

– GAVI window reopened
– Establish visit in 2nd year

Guiding principles
• Immunization system
strengthening
• Synergies, rubella, polio etc.
Summary
 Remarkable progress
– ¾ reduction in measles deaths and reported incidence rate
– Elimination of measles and rubella in the Americas
 Progress in India and China
 New tools for diagnosis and vaccination
 Challenges:
– Levelling off coverage, incidence, deaths
– Declining resources
25 |
Critical Issues
 Common vision and goal
– Measles Initiative Joint Declaration - does it need revising?
– Position of rubella?
 Resource mobilization
– Measles the invisible gorilla!
– Advocacy and resource mobilization plan?
 Contribution to systems strengthening
– Indicators to document contribution
 Outbreak tracking and response
– Role for a vaccine stock-pile
