For civilians. The US military has never stopped vaccinations against smallpox. All new recruits get vaccinated when they join. After 9/11 members of congressional leadership and the executive branch got vaccinated. There was an attempt to get essential civilians vaccinated after 9/11, but that stopped after several people had heart attacks. It's a rare symptom, but it does happen.
Thanks for your post. I knew that since I have/had family in the military. Quite frankly, I was upset when they stopped it for civilians. It was obvious to ME that it could easily creep back in due to world travel.
