Detailed explanation-2: -How are vaccines produced? Vaccines are made from dead (inactivated) or modified (attenuated live) whole microbes, or from inactivated or recombinant parts of microbes that are responsible for disease (such as toxins or surface proteins).

Detailed explanation-3: -Describe the process of vaccine production. Vaccines contain attenuated disease-causing organisms or toxins that initiate an immune response in the body. The first step in vaccine production is to prepare the antigen. Viruses are grown in the primary or cultured cells, bacteria are grown in the bioreactors.
