Smallpox vaccine is made from a live virus called "vaccinia." This live virus helps the body develop immunity to smallpox disease. When you receive smallpox vaccine,
the smallpox vaccination site contains a very small amount of vaccinia, which can be spread to other people. Accidental spread of vaccinia from the vaccinated
person to an unvaccinated person (contact) is known as contact transmission.
The Department of Defense recommends that people who receive smallpox vaccine who live with a high-risk close contact obtain alternate lodging.
*Close contact includes sexual activity, sharing a bed, bathing, contact sports activities, and rough-housing
If you have questions or concerns, discuss them with a provider and contact the Worldwide DHA Immunization Healthcare Support Center.
