[Asia Economy Reporter Kim Seul-gi] It has been revealed that some quantities of influenza (flu) vaccines, which were suspended from use due to 'room temperature exposure' incidents, were distributed in the market.


According to quarantine authorities and the medical community on the 25th, among the flu vaccines delivered by Shinseong Pharmaceutical, which has a supply contract with the government, to frontline hospitals and public health centers until the 21st, some were reportedly actually used for vaccination.


The Korea Disease Control and Prevention Agency (KDCA) has confirmed this fact and is currently verifying the distributed quantities and the number of people vaccinated.


The government confirmed that Shinseong Pharmaceutical, which signed a supply contract for 12.59 million doses (one dose per vaccination) of flu vaccines this year, violated the 'cold chain' principle during delivery by leaving the refrigerated truck door open or placing products on the ground, and consequently suspended the vaccination program from the night of the 21st.



The quantity suspended due to room temperature exposure is 5 million doses. These doses were scheduled to be used for vaccinations of 13-18 year-olds starting from the 22nd, but some hospitals, unaware of the suspension order, reportedly used these vaccines on the morning of the 22nd.
