Doctor Nancy Cox, who grew up on a farm near Spencer, is the chief of the influenza division at the Centers for Disease Control and Prevention.
She says no vaccine to protect against the bird flu is available yet. At least three vaccines are under development, but there is no timeline on how soon a vaccine might be available.
She says three previous pandemics, or global epidemics of flu in 1918, 1957 and 1968, struck without warning.
Cox was in Iowa City on Friday for a series at the University of Iowa’s College of Public Health.
