Introducing Vaccines...
This is a series of posts that are long overdue. In this series, I wish to share what I have learnt in the area of Bioprocess Engineering to all readers. In the first sharing of this series, I would like to share my experience on vaccine production during my tenure as an intern in Malaysian Vaccine and Pharmaceuticals.
So what is vaccine? Vaccine is an antigen used to establish immunity towards a certain disease. So the main difference between drugs and vaccines is vaccine PREVENTS disease before it occurs meanwhile drugs CURE the disease after it occurs.
There are two types of vaccines, which are known as killed and live vaccine. Killed vaccine contains previously virulent microbes which have been killed by heat or chemicals, while live vaccine contains viable, attenuated microbes. The vaccines are also classified based on the micro-organism used, literally viral vaccine which means vaccine from virus and bacterial vaccine which means vaccine from bacteria.
