Smallpox Autoinoculation Via Tattoo in a Soldier.

Area of Science:

• Immunology
• Dermatology
• Public Health

Background:

• The National Smallpox Vaccination Program has inoculated over 2.4 million military personnel since 2002.
• Smallpox inoculation and tattoos share similar administration methods involving skin trauma and can cause local immune dysregulation.
• Previous research warns of complications when tattoos and smallpox inoculations occur in close proximity on the same skin area.

Purpose of the Study:

• To present a case of smallpox autoinoculation in a soldier who received a tattoo over the inoculation site shortly after vaccination.
• To illustrate potential risks associated with traditional smallpox vaccination administration and patient adherence to aftercare instructions.

Main Methods:

• Case report of a military servicemember.
• Review of existing literature and adverse event reporting systems.

Main Results:

• The soldier developed autoinoculated smallpox lesions after receiving a tattoo four days post-vaccination.
• Reported symptoms included fevers, chills, myalgias, and suspected secondary infection.
• The Vaccine Adverse Events Reporting System (VAERS) database contains 13 reported cases of tattoo and smallpox inoculation complications over 15 years.

Conclusions:

• This incident underscores the risks of current smallpox vaccination practices and inadequate patient adherence to post-vaccination care.
• Current US Army Public Health Command (USAPHC) guidance recommends a 30-day tattoo restriction post-inoculation, with potential extensions.
• Enhanced education and emphasis on proper inoculation site aftercare are crucial for continued traditional smallpox vaccination.
