Why should the nurse remind an older patient to receive a pneumococcal vaccination at the age of 65?
1. Increased production of IgE
2. Decline in antibody response
3. Decreased antibody production to self
4. Increased speed of the cellular response

Rationale: Over time, the secondary immune response may also show changes. The number of B cells in the circulation decreases in some individuals. As a result, tissues are slower to repair and are more vulnerable to disease, especially infections. A decline in the production of IgE leads to a decrease in allergic or hypersensitivity reactions.
