As measles resurges globally, the debate over vaccination is taking a new turn. Calls to administer separate measles, mumps and rubella vaccines instead of the combined MMR vaccine have raised questions about what such a shift could mean for immunisation worldwide.
Policy changes could affect vaccine production, supply chains and access, particularly in lower- and middle-income countries. At the same time, misinformation can erode confidence in vaccines and public health institutions. The challenge extends beyond any single vaccine or policy. It is about sustaining the trust, access and systems needed to ensure that proven public health interventions continue to work in the real world.
Hear from Prof Teo Yik Ying on why protecting public health requires not only herd immunity and equitable vaccine access, but also societal immunity against misinformation.
