Benign hypersensitivity reactions to smallpox vaccine.

Background: With the reinstitution of smallpox vaccinations, physicians are seeing significant numbers of adverse events for the first time since the 1980s. The most common adverse events seen in our large military population are benign. We observed a clinically and histopathologically distinct reaction pattern that has not been fully characterized previously.

Conjugal transfer vaccinia.

Two cases of conjugal contact transfer vaccinia are described. Each patient had intimate contact after their respective partners, active-duty military personnel, received the smallpox vaccination.
