[Asia Economy Reporter Seongpil Cho] It has been confirmed that there have been 30 cases in South Korea where individuals tested positive for COVID-19 after receiving their first dose of the vaccine.

According to the COVID-19 Vaccination Response Task Force (Task Force) on the 20th, by comparing the reported confirmed cases with vaccination registration records, a total of 30 people were confirmed positive after vaccination as of midnight the previous day. By vaccine type, 27 cases involved the AstraZeneca (AZ) vaccine, and 3 cases involved the Pfizer vaccine. Regarding the timing of confirmation, 13 cases (43.3% of the total) tested positive within one week (7 days) after vaccination. The remaining 17 cases were confirmed between 8 to 14 days, that is, during the second week after vaccination.

By gender, females accounted for 23 cases, which was more than males (7 cases). By age group, those in their 30s were the most with 9 cases, followed by those in their 20s and 50s (7 cases each). Looking at the occupations of the confirmed cases, the majority were healthcare workers and medical staff. Among them, 19 were healthcare-related workers such as physical therapists, clinical pathologists, nutritionists, and nursing assistants, 10 were medical professionals, and 1 was a patient.

At the regular briefing that day, Bae Gyeong-taek, head of the Task Force’s Situation Management Team, explained, "It is presumed that the confirmed cases were infected before or immediately after receiving the COVID-19 vaccination, before immunity had been established." He added, "We will continue to monitor the occurrence of confirmed cases among vaccinated individuals over time and conduct evaluations of the vaccination’s effectiveness."
