Status of UNEP Negotiations affecting vaccine preservative Thiomersal Julia Hill CSO SC Meeting Dhaka, Bangladesh 11/11/11 Julia.hill@geneva.msf.org
Overview • Background on Thiomersal • Ongoing UNEP negotiations & possible effect on thiomersal • Update from UNEP INC3 in Nairobi • Next steps • Further resources
Thiomersal • WHO-approved vaccine preservative, prevents contamination of multi-dose vials • Used in multi-dose presentations of: DTP, DT, TT, HepB, Hib, influenza, Men A conjugate, (theoretically PCV) • NOT used in live vaccines: MMR, polio, yellow fever, BCG • Thiomersal-containing vaccines used in over 120 countries, averted >1,400,000 child deaths in 2010 • Contains ethyl mercury. The WHO, U.S. and European regulatory authorities have found no evidence that thiomersal’s use in vaccines poses a health threat
UNEP Negotiations: legally binding instrument on the use of mercury • Goal: limit exposure to and effects of anthropogenic mercury releases in the interests of health and the environment • Negotiators typically sit in Ministries of Environment or Finance • Last week in Nairobi: 3rd Session of Intergovernmental Negotiating Committee (INC3) convened • Current draft lists thiomersal on list of potential products that could be banned • An outright ban would mean multi-dose vials of affected vaccines could no longer be produced by or sold to country signatories
What would a ban on thiomersal likely mean in practical terms? • LIMITED ACCESS TO VACCINES! • Worst case scenario: Suppliers switch to single-dose vials of affected vaccines prices rise cold chain requirements increase suppliers may be unable to maintain current production volumes (prices rise more) some developing countries can’t afford cost or cold chain expansion, or vaccines are not available • Testing or developing other vaccine preservatives would require WHO to re-prequalify new multi-dose formulations (years-long process)
INC3 Nairobi: Oct. 31-Nov. 4, 2011 • WHO does MoH outreach in INC3 run-up, provides technical advice at INC3 • Where do various actors stand? • Anti-ban: • WHO, GAVI, CSO SC (released statements) • USA, EU, Norway, Canada (flu vaccine) • China (traditional medicines containing mercury) • Brazil, Korea, Cuba, Mali, Togo, Madagascar, CAR, Kenya, Tanzania, Cote d’Ivoire, many others • Wavering/Uncertain/Need more information: • Nigeria (want to switch to non-mercury preservative) • AFRO (want phase-out of thiomersal over time) • Mexico, Honduras, Pakistan (need more information) • Pro-ban • Chile (autism activist), South Africa (anti-vaccine Env. Minister)—causing uncertainty amongst some African and Latin American reps • CoMed, SafeMinds (anti-thiomersal activists)
INC3 Nairobi: Oct. 31-Nov. 4, 2011, cont. • Contact group set up to discuss “products and processes”; met twice at INC3 • Potential options for solutions: • Positive list (exemptions) • Negative list (prohibited) • Hybrid +/- : list prohibited products but allow for temporary exemption period • Voluntary by country—no regulation • Many countries want to move to mercury-free products, provided these alternatives are: • Economic • Technically feasible • Available without interruption in supply during transition • (Note: this is closest to the hybrid solution)
Next Steps • Negotiation rounds will continue: INC4, 25-29 June 2012 • WHO actions: this week SAGE endorsed proposal for scientific meeting on thiomersal alternatives, and review of policy implications prior to INC4; need to develop country-level action plan with Regional Advisors • Before INC4, need to provide authoritative evidence to countries on: • Alternative preservatives (2 phenoxy-ethanol) • Economic, programmatic, manufacturing implications of moving to single-dose preservative-free vaccines • Call next week between WHO, PATH, CSOSC rep, others involved, to discuss next steps • CSO SC thoughts or suggestions for possible solutions, next steps? Lobbying capacity in key countries?
