A total of 59 people, mostly those in their 70s and 80s, have now died after receiving flu shots, up from 48 as of Saturday.
However, the Korea Disease Control and Prevention Agency(KDCA) said in a Monday press release that it will continue its nationwide vaccine program, stating there is a very slim chance of a link between the shots and deaths.
So far, authorities have analyzed a total of 46 deaths and did not find any acute abnormal reaction that may occur after a flu shot in any of the cases, nor any serious atypical reactions.
As such, the nationwide influenza vaccination program will continue, though authorities will closely monitor possible links as one-thousand-231 people have reported side effects after getting shots this year as of Sunday.
The KDCA said it is currently looking into the remaining 13 cases and will monitor future cases.
