  1. Investigation into how the process of aging modifies immune responses to respiratory pathogens, thereby leading to impaired viral clearance, and alterations in long-term immunity to these pathogens.
  2. Examine how aging in the presence of a chronic viral infection impacts immune system function, thereby leading to increased susceptibility of chronically infected hosts to secondary respiratory pathogens.
  3. Examination of innate immune responses to primary influenza viral infections and secondary bacterial infections and how these responses are altered in aged hosts.
  4. Investigate how age induced inflammatory responses alter vaccine efficacy and design of potential therapies to augment innate anti-viral immune function with aging.
