Today we are highlighting the publication "Flu Vaccines in Older Adults"
This study looked at how the immune systems of older and younger adults respond to the flu shot. Researchers compared adults 65 and older to adults less than 45. They found that older adults produced similar levels of antibodies as younger adults after vaccination. However, older adults had fewer immune cells that help fight viruses and support a strong immune response. They also found changes in the activity of certain immune cells that may weaken the body's ability to protect against the flu. These findings suggest that future influenza vaccines should be designed to improve both antibody and immune responses in older adults.
