On the morning of September 22, a large hospital in Sejong City will post a notice to postpone free vaccination against influenza (flu). On the 21st of last month, the Korea Centers for Disease Control and Prevention announced on the 21st of last month that it plans to temporarily suspend the national influenza vaccination because it found a problem in the distribution process of influenza procurement contractors. .

Amid the unprecedented government suspension of the free vaccination business due to a problem in the distribution of the influenza (flu) vaccine, 873 people (as of 7 pm on September 29) have already received the problematic vaccine. None of the vaccinators who received the vaccine known to have been exposed to room temperature showed adverse reactions.
The Korean Centers for Disease Control and Prevention (KCDC) said in a regular briefing held last month 28 that no significant adverse reactions were identified among vaccines suspected of being exposed to room temperature. “There was a report of pain at the site where a person was injected on September 27 (vaccinated),” said the Office of Prevention and Medical Safety of the Yangdong Gyo Disease Office. “No other adverse reactions were reported.” This inoculator is said to have relieved pain and returned to normal.
On the 29th of last month, in Jeonju, where the most suspected cases of vaccination due to exposure to room temperature were reported, there were reports that an 8-month-old boy had symptoms of paralysis in the legs, but the vaccine was not acquired by the country . The Agency for Disease Control and Prevention confirmed that the boy had not supplied government purchases to vaccinated lawmakers.
Typical side effects of flu vaccines are allergies, fever, and seizures. Symptoms usually appear 1 to 2 days after vaccination. In a regular briefing on the 28th of last month, Chung Eun-kyung said in a regular briefing on the 28th of last month: “Because vaccination is usually an antigen and protein component, some adverse reactions are reported in any vaccine. Or local pain (the rate at which it appears) is usually reported in the 10-15% range. Adverse reactions disappear in a day or two. ”
“Because the flu vaccine is made especially by putting a virus in eggs (fertilized eggs), if you are allergic to egg protein, you may have a more serious allergic reaction.” Additional.
Because the national influenza vaccine was exposed to room temperature during distribution, the vaccination program came to a complete halt. Kim Jin-moon, president of Shin Sung Pharmaceutical, in charge of the vaccine distribution, apologized for the suspension of the vaccine.

Currently, the Agency for Disease Control and Prevention believes that not all vaccines already vaccinated have been exposed to room temperature and is investigating how many of them have been exposed to room temperature. Additionally, some of the 5 million doses (for 5 million people) distributed by Shinsung Pharm, a flu vaccine procurement company, have been exposed to room temperature, and the pool is collected and tested for quality. . The amount suspected of being exposed to room temperature is 750 doses (for 750 people).
The government and the Korean Centers for Disease Control and Prevention (WHO) indicated that flu vaccines are safe for 2 to 4 weeks at 25 degrees and 24 hours at 37 degrees, referring to data published in 2012 by the World Health Organization (WHO). Killed vaccine refers to a vaccine that is produced by killing pathogens, that is, inactivating them. In a regular briefing on the 25th of last month, Chung Eun-kyung, head of the Korea Disease Administration, said: “I think the possibility of contamination from vaccines is very low. “Because not all vaccines are problematic, excessive anxiety is unnecessary.”
Aside from side effects, the concern is that protein in the vaccine that has been exposed to room temperature for a long time may be affected and the effectiveness of the vaccine may decrease. This is the possibility of the so-called “water vaccine”. The Ministry of Food and Pharmaceutical Safety is taking this into account and examining it.
On the 22nd of last month, the Agency for Disease Control and Prevention announced the suspension of free flu vaccines and predicted that it would take about two weeks to perform quality tests. As expected, the flu-free vaccination program is expected to resume in early October, when the Chuseok holiday ends.
