This is the first of a new monthly series on Public Health with Azrul Mohd Khalib, CEO of Galen Centre for Health & Social Policy. Malaysia’s National Immunisation Programme is a success story. We have kept deadly infectious diseases at low levels and even eradicated some of them. However, we may see all our progress being derailed by the growing anti-vaccination movement. Dr Rohani bt Jahis, Head of the Vaccine Prevention of Disease/Food & Water Borne, Ministry of Health, and Datuk Dr Musa Mohd Nordin, Consultant Paediatrician and Neonatologist, look at what policies have achieved so far – and what it will take to convince the anti-vaxxers.
