How is smallpox vaccine given?
The smallpox vaccine is not given with a typical needle. It is not a shot, like many vaccinations. The vaccine is given using a bifurcated (two-pronged) needle that is dipped into the vaccine solution. A bifurcated needle looks like a little pitchfork or tuning fork. When dipped into the vaccine vial, the needle retains a droplet of the vaccine between the two prongs. The needle is then used to prick the skin 15 times in a few seconds. The pricking is not deep, but it will cause a sore spot and a very small drop of blood to form. The vaccine usually is given on the upper arm.
