Even one polio case is an outbreak

KUALA LUMPUR (Bernama): The three-month-old infant from Tuaran, Sabah who contracted polio was under-immunised with polio vaccine and was thus not protected, says consultant paediatrician and clinical immunologist Datuk Dr Musa Mohd Nordin.

According to the Malaysian National Immunisation Schedule, infants are to receive the inactivated polio vaccine (IPV) at ages two months, three months and five months. A booster shot also needs to be administered when the child is 18-months-old in order to be fully protected.
