In connection with the administration of the remaining amount for one person when vaccinating the new coronavirus infection (Corona 19), the head of the Korea Centers for Disease Control and Prevention (KCDC) is that 10 people (AstraZeneca vaccine) or 6 people (Pfizer vaccine) per vial (bottle) should be vaccinated in principle. Revealed again.
Existing guidance that you can inoculate on-site if an additional person is added from 1 vial using a minimum residual type (LDS) syringe is an exception to respond to situations caused by the on-site vaccine reserve or unexpected increase or decrease in the number of vaccinations. It is an explanation that it is the degree to which it was placed.
In a regular briefing for Corona 19 on the 1st, Chung Eun-kyung said, “It is judged that it is correct to inoculate in accordance with the original licensed content and usage.” “There is no plan to increase the amount of inoculation excessively with uncertainty. I will do it again.”
Currently, on average, AstraZeneca vaccine can be administered by 10 people per bottle and Pfizer vaccine can be administered by 6 people per bottle. Since the one-person syringe is not filled, the drug goes through the process of extracting the drug from the vial with the syringe, and in this process, the remaining amount is left in the vial in addition to the volume specified in the per person permission.
In particular, the LDS syringe can leave a lot of such residual amount unlike other syringes. Accordingly, the Agency for Disease Control and Prevention has sent a notice to the site so that the remaining amount in this bottle can be used for vaccination based on the on-site judgment if the amount of the remaining amount reaches one dose.
Some confusion occurred over the interpretation of the contents of these official documents. A misunderstanding has arisen that the use of an LDS syringe can uniformly inoculate one more person than the previously expected number of people. However, this turned out to be not true.
Commissioner Jeong said, “(In the case of Pfizer vaccine), it is absolutely not that you have to use 7 servings per vial (bottle). Depending on the product of the vaccine, you can uniformly subdivide into 7 servings per vial or subdivide 11 people. It can be done or it cannot be confirmed like this.
“Today, 10 people should be given, but when subdividing 1 person, it was not properly subdivided, or when the target was changed, one more person had to be added, but one bottle for 10 people should be opened and inoculated. “He added, “To minimize the amount of waste, it is said that it is used within the range of using the remaining amount.”
In addition, it is possible to administer the remaining amount for one person from one bottle, but he also advised that it is impossible to administer the remaining amount for one person collected from several bottles. This is because the possibility of external contamination cannot be excluded in the process of mixing drugs in vial using different syringes.
Commissioner Jeong said, “Of course, it is absolutely forbidden to collect the remaining amount and inoculate it,” he said. “If you use the remaining amount in multiple vials, the possibility of contamination in the mixing process is slightly higher, so such parts are prohibited.”
He said, “We will communicate more clearly to the field and supplement the guidelines so that this does not happen in the future.”
