According to the medical community on the 1st, on the second day of the AstraZeneca vaccination, on the 27th of last month when the Pfizer vaccine was first vaccinated, the Centers for Disease Control and Prevention (KCDC) issued an official letter to a frontline medical institution stating that additional vaccinations can be administered at the discretion of the field if the remaining amount after vaccination per vial. I sent it down.
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.”
Pfizer vaccine is recommended for 6 people per vial (bottle) and AstraZeneca vaccine is recommended for 10 people per vial. However, in the process of diluting and using the undiluted solution, 7 Pfizer vaccines and more than 10 AstraZeneca vaccines can be vaccinated.
Accordingly, there was an opinion that 7 people per vial of Pfizer vaccine can be vaccinated at the National Medical Center’s Central Vaccination Center, where Pfizer vaccination has been conducted for workers in the treatment hospital for COVID-19 patients from 9 am on this day.
National Medical Center Director Chung Ki-hyun told Prime Minister Jeong Sye-gyun, who visited the vaccination site, “(per vial of Pfizer vaccine) is about 0.45 ㏄, but if 1.8 ㏄ physiological saline is mixed, it becomes 2.2 ㏄.” “He explained.
Accordingly, voices mixed with worries poured out at once in the field. Above all, Pfizer vaccines, which are kept frozen in principle, must be defrosted the night before vaccination in accordance with the number of pre-booked people, but the uncertainty was too high.
It is criticized for creating more controversy by attempting to’squeeze the vaccine’ even though the government said that the vaccine is sufficiently introduced in Korea.
The COVID-19 vaccination response team said, “Regarding the remaining amount of vaccination, judgment is made according to the site situation, and the residual amount of vaccination itself is not mandatory.”
Concerns arise that the vague authorities’ position could put a burden on the medical staff. Even if it is not necessary to squeeze the 7 doses, the government’s guidance to make the most of the remaining amount will affect the vaccination site itself.
Some of the medical community criticizes, “Because there is no scale mark on the vial, it is a sound to check with the public eye to see if the remaining amount is 0.3ml or not,” and “If it comes out 0.28 or 0.29ml after putting it in a syringe, you will only discard a good syringe.”
Eom Joong-sik, a professor of infectious medicine at Gachon University Gil Hospital, told Facebook, “If the 7th dose is extracted incorrectly from the previous 6 people, we may not be able to obtain a sufficient amount.” Do you have it?”
In particular, there is concern that if the vaccination site goes too tightly due to the remaining amount of vaccine, the fatigue of the medical staff will increase and errors may occur.
For example, it is pointed out that contamination may occur if a bottle of Pfizer has 0.28 mL remaining, which is slightly less than the amount of one dose, if the vaccine is extracted from a new container with a syringe extracted from an existing container to fill the insufficient amount.
