During January 24–February 14, 2003, smallpox vaccine was administered
to 4,213 civilian health-care workers in 27 jurisdictions. No potentially
life threatening or moderate-to-severe adverse events have been reported.
Among seven vaccinees with reported nonserious adverse events, the most common
signs and symptoms were fever (n = two), rash (n = two), malaise (n = two),
pruritus (n = two), hypertension (n = two), and pharyngitis (n = two). Surveillance
for adverse events during the civilian smallpox vaccination program is ongoing.
Regular surveillance reports will be published in MMWR.
