National Disease Administration, an official letter to the national field… “If you use the minimum remaining syringe, you can use the remaining amount”
AZ vaccine 10 people → 12 people, Pfizer vaccine 6 people → 7 people using a domestic syringe
“It is only possible to reduce the amount of waste, and the dose per dose must be kept”
The Korea Centers for Disease Control and Prevention has allowed the number of people to be vaccinated per vial (bottle) of the novel coronavirus infection (Corona 19) vaccine used in Korea to be increased by 1-2 at the site.
When using a special’low dead space, LDS’ developed by domestic companies, the number of people vaccinated per bottle of Pfizer vaccine is 6 to 7 people, and the number of people vaccinated for AstraZeneca (AZ) vaccine is 10 people. It announced a guideline saying that it is safe to increase the number to 11-12.
This is the first time in the world to increase the number of people vaccinated per bottle of vaccine like this.
This is to reduce the amount of discarded vaccine as much as possible, and depending on the skill level of the nurse in charge of the vaccination, the number of vaccination personnel may increase significantly with a limited vaccine.
◇ An official letter on the’Residual amount available’ site… “Dimensions of offsetting and reducing waste volume”
The Corona 19 Vaccination Response Promotion Team announced on the 27th that it has distributed “how to conduct vaccinations” with these details to vaccination sites nationwide.
The promotion team explained in the official letter, “When using the minimum residual sterilized syringe, if the remaining amount remains after the inoculation for the recommended number of inoculations per vial, additional inoculation is possible in order to reduce the waste amount.”
The minimal residual syringe is a special syringe that has little space between the piston and the needle to minimize discarded vaccine.
A government official said, “If you use a special syringe, you can use the remaining amount additionally,” he said. “AstraZeneca can fit 10 people per bottle. Depending on the remaining amount, up to 11 to 12 people can be inoculated.”
Chung Kyung-sil, head of the vaccination management team of the promotion group, said at a briefing that day, “depending on the skill level of the vaccination personnel, there may be less than 6 people out of one Pfizer vaccine, or more than 6 people.” “I want to use the remaining amount.”
He emphasized, “However, the prescribed dose must be adhered to, and it is absolutely forbidden to collect and use the remaining amount from each bottle.” He emphasized, “The remaining amount of inoculation should be judged according to the site situation, and the remaining amount of inoculation itself is not mandatory.” did.
◇ Currently inoculating with an LDS syringe… If the nurse skill is high, the remaining amount can be inoculated.
The National Medical Center said it would verify the possibility of expanding the number of vaccinations on the day of the first vaccination of Pfizer’s vaccine.
Jeong Ki-hyun, the head of the National Medical Center, also visited the vaccination and said, “When the frozen Pfizer vaccine is defrosted, there is about 0.45 ml, and when 1.8 ml of physiological saline is mixed, the total amount becomes 2.2 ml. He said, “I will verify the method of expanding the number of vaccinations on this day.”
According to the standard vaccination method suggested by the authorities, Pfizer vaccine is made by mixing 1.8 ml of saline solution with 0.45 ml of undiluted solution, and 0.3 ml of each person is inoculated.
AstraZeneca vaccine contains more than 5 ml of medicine in one bottle, and 0.5 ml per person is inoculated.
The standard number of vaccinations per bottle is set at 6 Pfizer and 10 AstraZeneca.
However, LDS syringes are used for both vaccines’ initial dose inoculation.
Even if all the prescribed doses are kept, there is room for a residual amount to remain.
Additional vaccination is possible with a vaccine determined according to the skill level of the on-site nurse.
The authorities have distributed 670,000 LDS syringes to inoculation institutions so far.
Domestic manufacturers Doowon Meditech and Shin-A Yanghaeng supplied them, and Poonglim Pharmatech donated 127,000 to the government ahead of export to the United States.
Assuming that the number of inoculations per bottle of Pfizer increases from 6 to 7, the number of inoculations can be increased by 16.7% arithmetically.
If the number of AstraZeneca vaccinations increases from 10 to 11 to 12, the number of vaccinations increases by 10 to 20%.
The government has signed a purchase contract for 13 million people through a direct contract with Pfizer and 10 million people through a contract with AstraZeneca, apart from Kovacs.
The previous day, 58,000 Pfizer vaccines were supplied through the COVAX facility, an international vaccine supply organization.
