Meeting report summary focused on WHO's informal consultation (April 2012) regarding vaccines for UNEP's Intergovernmental Negotiating Committee Meeting 4 (INC4). The discussions centered on thiomersal, an organic mercury preservative in multi-dose vaccines, and the global transition to alternative preservatives or single-dose formulations.

Key topics included: concerns over mercury reduction via a global legally binding instrument, evaluation of thiomersal's safety (benefits outweighed risks based on data), limitations of alternatives (e.g., limited data, unpredictable interactions, high costs), and implications for immunization programs, including potential increased costs, storage challenges, waste management issues, and disruptions in low/middle-income countries. Veterinary vaccines were also addressed, highlighting similar dependencies on thiomersal and impacts on animal/human health.

Findings emphasized that restricting thiomersal could severely affect vaccine supply, public health, and economic stability. Recommendations urged continued surveillance, development of new vaccine technologies, and cautious policy-making based on evidence.
