4 Breakthrough Infections at Hospital in Jung-gu, Daejeon

[Asia Economy Reporter Minji Lee] In a hospital in Jung-gu, Daejeon, six people including patients and staff tested positive for COVID-19, among whom four are confirmed to be suspected cases of 'breakthrough infection' after completing vaccination.

On the 17th, the Central Disease Control Headquarters (CDCH) stated in a reference document regarding the cluster infection case at the hospital in Jung-gu, Daejeon, "As of yesterday, six confirmed cases occurred, and among them, four are suspected breakthrough infection cases."

Breakthrough infection refers to cases where individuals have received all recommended doses of the vaccine within the prescribed period and tested positive 14 days after vaccination. The classification of cases may change if epidemiological investigations later confirm exposure to the infection source before 14 days have passed after the second dose.

This is not the first suspected breakthrough infection case reported in domestic medical institutions. Previously, among nine confirmed cases related to a general hospital in Pyeongtaek, Gyeonggi Province, one was suspected to be a breakthrough infection case, and similar cases have been reported in a hospital in Jeonju, Jeollabuk-do.

As of the 13th, the total number of people who have completed vaccination in Korea is 4,167,322, and among them, the CDCH reported 252 suspected breakthrough infection cases. This corresponds to about 6.05 cases per 100,000 vaccinated individuals.

By vaccine type, Janssen accounts for the highest number with 143 cases, followed by Pfizer with 59 cases, and AstraZeneca (AZ) with 50 cases. The breakthrough infection incidence per 100,000 vaccinated individuals is 12.74 for Janssen, 5.96 for AZ, and 2.67 for Pfizer vaccines.
