In the latest Vaccine Smarts column by UTMB’s Dr. Richard Rupp and Bridget Hawkins: A reader called to let us know that some members of our military still get the smallpox vaccine. Vaccination has eliminated natural cases of smallpox. The last natural case of smallpox was in Somalia in 1977. The World Health Organization authorized only the Russian Federation and the United States to keep samples of the smallpox virus. The samples are solely for scientific study. Unfortunately, other countries and groups may possess the virus as well.
