The Korea Centers for Disease Control and Prevention, which is investigating the poor circulation of the national flu vaccine, said in an interim inspection on the 25th that “it was confirmed that 105 people were vaccinated with a vaccine that may have been exposed to room temperature “. The Agency for Disease Control said: “There have been no adverse reactions yet, but we will continue to monitor them.”
According to the Agency for Disease Control and Prevention, the amount of flu vaccine supplied nationwide through Shinsung Pharmaceutical amounted to 5.78 million people, and was supplied to 256 public health centers and 11,101 institutions. doctors across the country. As a result of a joint investigation by the Ministry of Food and Drug Safety and Gyeonggi Province on the 23rd by the Ministry of Food and Drug Safety, it was confirmed that the vaccine storage refrigeration warehouse of the service company in charge of local delivery was kept at 4-6 degrees Celsius, and an automatic temperature recorder was also installed inside the refrigerated car. .
Disease management said: “In the process of subdividing and classifying vaccines in refrigerated 1-ton trucks in some areas, it was reported that they were exposed to room temperature on roads for a certain period of time, and the vaccines are being verified details “. According to the Agency for Disease Control and Prevention, 750 samples are being taken and analyzed for 600,000 to 750,000 people in five areas where the vaccine suspected of being exposed to room temperature was initially given.
The Agency for Disease Control and Prevention plans to expand the second inspection if the amount suspected of being exposed to room temperature is found in further investigation. The Ministry of Food and Drug Safety is conducting tests on the elements necessary to confirm the quality of the vaccine, such as an antigenic protein content test to confirm the efficacy of a vaccine suspected of being exposed to room temperature and a test of exothermic reaction to confirm safety. It will take about two weeks. “
According to the Agency for Disease Control and Prevention, influenza vaccines suspected of being exposed to room temperature maintain their quality for a minimum of 14 days up to a maximum of 6 months at 25 degrees Celsius in their own safety test. maker. The Agency for Disease Control and Prevention said: “According to data from the PATH (International Non-Profit Organization for Public Health Activities) provided by the World Health Organization (WHO), the quality of vaccines against flu stays 25 degrees at 2 weeks. “
At the expert advisory meeting organized by the Korea Disease Service and the Food and Drug Administration, “Considering the environment and the time of exposure to room temperature, the possibility of quality change is low due to the nature of the influenza vaccine supplied in a sealed state, but it is necessary to examine whether the effectiveness of the vaccine deteriorates when exposed to room temperature. There is.”
