Question

Quizplus · Accepted Answer

As people age, their adaptive immunity, which involves the body's ability to recognize and remember specific pathogens for faster immune responses in future encounters, tends to weaken. This decline is due to factors like reduced production of new immune cells and diminished function of existing cells, making older individuals more susceptible to infections, diseases, and reduced vaccine efficacy.
