MICROANATOMY

Detailed explanation-1: -Vaccines contain weakened or inactive parts of a particular organism (antigen) that triggers an immune response within the body. Newer vaccines contain the blueprint for producing antigens rather than the antigen itself.

Detailed explanation-2: -Live, attenuated vaccines fight viruses and bacteria. These vaccines contain a version of the living virus or bacteria that has been weakened so that it does not cause serious disease in people with healthy immune systems.

Detailed explanation-3: -Weakened Vaccines This pathogen is weakened, or attenuated, through culturing in a laboratory, making them safe to be administered to the majority of the community. After someone is vaccinated with a weakened vaccine, the virus or bacteria grows and replicates inside the body.
