Smallpox vaccine mainly adopts the needle prick method and scratch method for vaccination, but smallpox is already extinct in our country, so there is no need to take smallpox vaccine. 1. Needle puncture method: first disinfect the site to be vaccinated with medical alcohol, then aim the vaccination needle at the lower edge of the deltoid muscle of the upper arm of the person to be vaccinated at a perpendicular angle, with a puncture diameter of about 5mm, the first-time vaccinee only needs to be punctured for three times, and the re-vaccinated person is punctured for 15 times. The puncture force should be larger, and the operation is considered successful when a bleeding point appears at the puncture site in about 15-30 seconds. 2. Scratch method: In the attachment of the lower edge of the deltoid muscle on the outer side of the upper arm of the inoculated person, drop a drop of smallpox vaccine liquid, and then hold a sterilized needle in the vaccine liquid droplets to draw a horizontal line, generally 3-5mm, the strength of the epidermis needs to be scratched to make the scratching part of the appearance of unconnected small blood spots. Smallpox has been eradicated in our country, so there is no need to take smallpox vaccine.
