Recently, there was a very unfortunate case of a girl who passed away in Miri Hospital, Sarawak due to diphtheria at the age of two. This raised much concern over this archaic disease that, of late, is making a comeback.

As mentioned previously, the active component in a vaccine is the ‘antigen’. This can be in the form of weakened (attenuated live vaccine) or inactivated microbes, parts of microbes, or modified microbial toxins (toxoid vaccine).
