Question

Summarise the process of vaccine production

Answer 1

a.  Production of vaccines involves growing the organism in a growth medium to      produce large amounts of toxins. 
b. These toxins are then altered to give toxoids which are no longer toxic. These      toxoids become antigens which the immune system recognises, and hence          produces antibodies to act against genuine toxins.
c. The live organisms in the culture are inactivated, and the resulting mixture is       diluted and mixed with an adjuvant

d. The blended vaccine is then filled and packed.
