Innocent children have the right to play without fear of catching measles, pertussis, chickenpox and so many other diseases from their friends whose parents refused to vaccinate them, said paediatrician and neonatologist Dr Musa Mohd Nordin.

Dr Musa, who is the Consultant Paediatrician and Neonatologist at Damansara Specialist Hospital, said the children would have 23 times increased risk of pertussis, nine times of chickenpox and other diseases if their parents refused to vaccinate them.
