Answer: The correct answers would be:

1: a) antibody

2: a) immunologist memory

Explanation:

Vaccination is one of the processes which helps in the development of adaptive immunity.

It is the process by which heat-killed or weakened pathogen is inserted into the body. The weakened organism acts as natural pathogen for the body due to which body it produces antibodies and memory cells.

Due to weakened pathogen, it does not produce disease.

On secondary exposure to the same pathogen, the body produces greater and faster response due to immunological memory.
