In Korea, vaccine vaccination for a novel coronavirus infection (Corona 19) developed by Pfizer is starting. At 9 am on the 27th, 300 corona treatment medical staff will receive the first Pfizer vaccine in Korea at the Central Vaccination Center in the National Medical Center in Jongno-gu, Seoul. The Pfizer vaccine is difficult to store, transport and inoculate.
According to the Korea Centers for Disease Control and Prevention, the single dose of Pfizer vaccine is 0.3mL. One vial (bottle) of injection contains 6 doses, and in order to extract it at a time, a minimum residual syringe (LDS) must be used. If you use a regular syringe, you can only use 5 times.
Pfizer vaccine stored at cryogenic temperatures is thawed for 30 minutes at 2-8°C (takes about 3 hours) and room temperature (maximum 30°C) before inoculation. After that, you need to dilute the injection. Using a dilution syringe, add 1.8 mL of 0.9% physiological saline injection to the vial containing the vaccine. Mix the vial containing the diluted solution by gently inverting it 10 times, but never shake it.

“The Pfizer Corona 19 vaccine is an mRNA vaccine, which contains the information of the antigenic protein of the Corona 19 virus, and the lipid nanoparticles that protect it and help it enter the cell from the body. It is composed of,” he said. “Both mRNA and lipid nanoparticles are chemically safe and not a tight bond. Therefore, the structure can be easily decomposed by physical force, so care must be taken when handling the vaccine, and never shake it.” The diluted vaccine should not be moved by vehicle, etc.

The Pfizer Corona 19 vaccine diluted in this way has a maximum exposure time of 6 hours at room temperature. After extracting 0.3 ml of Pfizer’s Corona 19 vaccine diluted in a syringe with an LDS syringe, intramuscular injection is placed on the deltoid muscle on the upper part of the forearm. The second vaccination is completed 21 days after the first vaccination.
