Summarise the process of vaccine production
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.
