| 製品概要: |
Bifurcated needles have two prongs. A small drop of smallpox vaccine was placed between the prongs and approximately fifteen punctures would be made into the skin. The needles were easy to use and the technique could be learnt by anyone, making effective widespread vaccination possible. The needles were sterilised by boiling or passing through a flame. The skin was not disinfected before use as this killed the vaccine.
