Immune function wanes in all adults—whether healthy or sick—as they age into their fifth decade and beyond. Their bodies become less adept at recognizing and stopping pathogens, and the ability to develop and maintain immunity declines. Also known as immunosenescence, age-related decline in immunity significantly contributes to the susceptibility of older adults to serious conditions, including influenza, pneumonia, and shingles.

The following infographics explain these concepts in easy-to-share formats. See the link below each infographic for a PDF copy.
