Abstract:
Older people exhibit increased morbidity and mortality after viral infections than younger people. Additionally, vaccines are less protective in older people than in younger people. As the immune system is critical for host defense to viral infections and for vaccine efficacy, the implications are that aging negatively affects immunity. The immune system is broadly categorized into adaptive and innate systems. The innate immune system acts as a first line of defense to pathogen invasion. In this review, I focus on how aging affects the innate immune response to viral infection.

NK Cells
NK cells are a crucial part of our innate immune system, acting as the first line of defense against viral infections. These cells can recognize and kill infected cells without prior exposure to the virus, effectively slowing down the spread of infection. Additionally, NK cells produce proinflammatory...

Innate immunity is the body's natural, nonspecific defense system that acts quickly to protect against pathogens. It incorporates physical barriers like skin and mucous membranes and cellular elements such as phagocytes and natural killer cells. This part of our immune system provides an immediate,...
