The Korea Centers for Disease Control and Prevention (KCDC) said that the number of people who reported having had an abnormal reaction after receiving the flu vaccine, which had been discontinued due to'room temperature exposure' during the distribution process, increased from 4 to 8.
Of the four newly reported adverse reactions, two reported symptoms of chills, headache, and nausea, one for hives, and one for diarrhea.
They had symptoms after vaccination, but they were in an improved state, the disease agency explained.
Four people who were previously reported to have adverse reactions also had symptoms such as fever and chills, but improved.
A total of 5.78 million vaccines are currently discontinued due to room temperature exposure.
Initially, the Agency for Disease Control and Prevention announced that'no one has received the vaccination in question', but there are several cases of vaccination during the investigation process.
Since the 25th of last month, the cumulative number of vaccinations has increased daily, such as 105 people → 224 people → 324 people → 407 people → 873 people → 1,362 people.
