In July, the National Institute of Health investigated the presence of coronavirus antibodies in the blood of 9,901 Koreans.



97.38% had antibodies, and antibodies generated by natural infection were found to be 57.65%.



The retention rate of naturally-infected antibodies was 19.5 percentage points higher than the cumulative number of confirmed cases in Korea, meaning that about 10 million people were infected with the coronavirus but were not caught in the statistics.

The rate of unconfirmed infection by age was highest in those in their 50s and 40s, when the vaccination rate reached 99%.



The quarantine authorities analyzed that they may have been ill after being vaccinated and may have passed without knowing it or may have avoided testing.



Recently, in the three major medical journals, hybrid immunity with both a vaccine antibody and an infection antibody is the strongest, and it was 96% more effective in preventing infection than having one antibody, and it lasted longer than 5 months.



In Korea, the hybrid immunity rate was higher among those in their 30s and younger, and dropped sharply from those in their 70s or older.



There is a need to establish a vaccine policy by infection status, frequency of vaccination, and age group.
