Which of the following is an age-related change associated with the immune system?

According to the National Institutes of Health, the immune system of older individuals responds less efficiently to novel or previously encountered antigens. This decline, known as immunosenescence, answers the question: "Which of the following is an age-related change associated with the immune system?". It is characterized by widespread changes affecting both the adaptive and innate immune systems.
