Question

Vaccinations elicit a primary immune response so that secondary immune responses are rapid and symptoms are mild. vaccinations elicit a primary immune response so that secondary immune responses are rapid and symptoms are mild.

a. True
b. False

Answer 1

Vaccinations prompt a primary immune response which establishes immune memory, allowing for a rapid and strong secondary immune response upon re-exposure to the pathogen, often preventing illness. This statement is true.

Step-by-step explanation:

The statement that vaccinations elicit a primary immune response so that secondary immune responses are rapid and symptoms are mild is true. Vaccination introduces noninfectious antigens to the body, prompting a mild primary immune response that doesn't cause illness but establishes immune memory. Upon subsequent exposure to the same pathogen, the body's immune system can mount a quick and robust secondary immune response, often preventing the pathogen from causing significant illness. To maintain this heightened state of readiness, booster vaccinations might be necessary, as they help to replenish memory cells that can die off over time.

Answer 2

The answer would be true

The objective of vaccination is to elicit the primary immune response by introducing pathogen antigens. This antigen can be a whole weakened pathogen or just part of pathogen proteins.
The antigen will activate the primary immune response cascade that will activate of B-cells and T-cells from the secondary immune response. This will makes secondary immune response ready when the real pathogen comes.
