Amid successive deaths after vaccination against influenza (flu) vaccination, it was argued that the cause of the accident could be toxins (toxic substances) in fertilized eggs used as vaccine raw materials or uniformity.



Rep. Kang Ki-yoon of the National Assembly's Health and Welfare Committee (the power of the people) died if toxins or bacteria were present when the flu virus was added to fertilized eggs and cultured in fertilized eggs after consulting with Professor Sang-hee Seo of the Department of Veterinary Medicine at Chungnam National University. They said they have confirmed that it can cause a shock that leads to.



After vaccination, serious side effects such as'Guillain-Barre syndrome' or'anaphylactic shock' may occur.



Guillain-Barré syndrome refers to a nervous system disease that causes paralysis by destroying the peripheral nerves by antibodies induced by infection.



Anaphylaxis is a serious allergic reaction that occurs systemically within minutes or hours after exposure to a causative agent such as certain foods and drugs.



Rep. Kang explained that toxins or bacteria in fertilized eggs can affect the inoculator's autoimmune system, attacking normal tissues of the body, or causing an allergic reaction by itself, resulting in shock.



He pointed out that when the Ministry of Food and Drug Safety approves the shipment of vaccines, only some quantities are tested for sterility and toxins by sampling method.



In addition, they argued that the vaccine manufacturer's production process or the status of bacteria and toxins in the vaccine before distribution or vaccination were not separately checked.



Rep. Kang said, "We can't rule out the case of using regular eggs, which are urgently manufacturing a large amount of government procured quantities of 19 million doses, and bacteria and toxins can exist above the standard value." And we need to investigate the status of the vaccines already in circulation.”



In response, Lee Eui-kyung, head of the Food and Drug Administration, attended the National Audit of the Health and Welfare Committee held at the National Assembly today and said, "We are thoroughly managing all processes including vaccine manufacturing, production, and quality control. We also regularly inspect fertilized egg production facilities to ensure that there are no problems." .



"The manufacturing process also undergoes aseptic filtration and purification, and, unlike other products, it receives national shipment approval from the Ministry of Food and Drug Safety." "In that process, the sterility test and endotoxin (intratoxin test) test were randomly collected. "We are managing sterility in double and triple."



He added, "These management standards are inferior to global standards, and Korea's quality control level is internationally recognized so that some vaccines supplied to the UN by WHO (World Health Organization) are entrusted to us for testing."



An official of the flu vaccine manufacturer also said, "We obtain data that there is no quality and safety even at the manufacturing stage of the manufacturer before the KFDA verification. Since the aseptic process is maintained in the process, the question of toxicity and germs is not correct."
