Vaccines tend to be less effective in older adults due to the natural decline in the immune system's functionality with age, a phenomenon known as immunosenescence. This makes the 64-year-old male client more likely to have a reduced response to vaccination compared to the younger female client, regardless of lifestyle factors.
