Purpose: The threat of smallpox resulting from bioterrorist action has prompted a reassessment of the level of immunity in current populations.
Methods: We have examined the magnitude and duration of antiviral antibody immunity conferred by smallpox vaccination in 246 participants of the Baltimore Longitudinal Study of Aging. Of this population, 209 subjects were vaccinated one or more times 13 to 88 years before this evaluation, and stored serum samples were available at various intervals after vaccination.
Objectives: To determine the changes in serum erythropoietin with age in patients with and without anemia and to assess the importance of certain comorbidities on changes in erythropoietin level and the development of anemia.
Design: Clinical history, hematological parameters, and serum erythropoietin levels were examined at 1- to 2-year intervals for 8 to 30 years.
Setting: Baltimore Longitudinal Study on Aging (BLSA), National Institute on Aging.
