Why are booster doses of some vaccines recommended?
To increase the number of antibodies in the blood
To decrease the risk of an adverse reaction to the vaccine
To provide immunity for a longer duration
To reduce the number of required vaccine doses
The Correct Answer is C
Explanation: Booster doses of vaccines are recommended to reinforce and extend the duration of immunity provided by the initial vaccination. They help the immune system to maintain a higher level of protection against the disease over time.
Incorrect choices:
a. The number of antibodies in the blood is not increased by booster doses; rather, the immune system's memory is reinforced.
b. Booster doses do not decrease the risk of adverse reactions; they are given to maintain immunity.
d. Booster doses do not reduce the number of required vaccine doses; they are additional doses given to maintain immunity over time.
