Antibody responses to specific antigens are generally impaired in the elderly. This is important because older people are often the target population for influenza and pneumococcal vaccination. Poor fever response in older patients may retard diagnosis of infection and sepsis

Ninety-five randomly selected patients attending an ambulatory geriatric medical clinic were tested for the presence in their sera of hepatitis B surface antigen and of antibody to hepatitis B and A viruses. Such evidence of past hepatitis infection was correlated with current liver function and history of having received blood transfusions. The results showed that 94% of patients had antibody to hepatitis A virus, and 32% had antibody to hepatitis B virus. Patients with abnormal liver function tests, or those with a history of blood transfusions were no more likely to have hepatitis B antibody than patients with normal liver function tests or those with no history of transfusion
