Identify "1" and "2" in the following diagram. Write in brief about production of vaccine.

Vaccine can be characterised as the introduction of the dead of living microbe into the body for instigating the immune cells to react and produce antibodies. In the given diagram 1 is antigen and 2 is adjuvant. A vaccine is produced on a large scale with precaution because it is to be administered to both children as well as adults. The first stage is Inactivation which is involved in the preparation of antigen. The microbe or the virus is made to proliferate in a primary cell such as a chicken egg. Once the microbe grows well, it may contain toxins and harmful substances. The second stage is purification which requires the isolation or purification of the antigen. The microbe is then isolated from the cell to weaken its strength and make it inactive. The third stage is formulation where the isolated antigen is mixed with adjuvants, stabilizers, and preservatives to form the final vaccine preparation. The role of the adjuvant is to enhance the immune response of the antigen. The stabilizers increase the storage life of the vaccine after it has been completely manufactured.
