[Asia Economy Reporter Lee Jung-yoon] The number of cases reported to health authorities suspected of adverse reactions after COVID-19 vaccination increased by 131.

The COVID-19 Vaccination Response Promotion Team announced on the 10th at midnight that there were 131 new cases reported of adverse reactions following COVID-19 vaccination.

Among these, the number of reported deaths increased by 2, bringing the total number of deaths to 44. Of the new deaths, one person received the AstraZeneca vaccine, and the other received the Pfizer vaccine. It has not yet been confirmed whether there is a causal relationship between the vaccination and the deaths.

Additionally, 2 new suspected severe cases such as neurological abnormalities including seizures or ICU admissions were reported. Both cases involved recipients of the AstraZeneca vaccine.

Four new suspected cases of anaphylaxis, a severe systemic allergic reaction, were added. Among them, one person received the AstraZeneca vaccine, and three received the Pfizer vaccine. The remaining 123 cases involved relatively mild symptoms such as muscle pain, headache, fever, chills, and nausea.

Since vaccinations began domestically on February 26, the cumulative number of suspected adverse reaction reports has reached 11,599. As of midnight on this day, this accounts for approximately 0.96% of the total 1,207,482 first and second dose recipients in the country.

Among all suspected adverse reaction reports, those related to the AstraZeneca vaccine accounted for 10,873 cases, representing 93.7% of all reports, while reports related to the Pfizer vaccine total 726 cases (6.3%) so far.

Looking at all reported adverse reaction cases to date, the cumulative number of reported deaths is 44. However, the damage investigation team has confirmed that most of the reviewed cases so far have no causal relationship with the vaccine.

Suspected anaphylaxis cases total 115 (99 AstraZeneca, 16 Pfizer), including 104 anaphylactoid reactions and 11 anaphylactic shocks. Suspected anaphylaxis cases are broadly categorized into anaphylaxis, anaphylactic shock, and anaphylactoid reactions. Anaphylactoid reactions refer to symptoms such as difficulty breathing or hives occurring within 2 hours after vaccination. Although these symptoms resemble anaphylaxis, experts explain that they can improve with symptomatic treatment and are generally not a major concern.

Furthermore, the total number of reported suspected severe adverse reactions is 27. Among these, 7 cases involved neurological responses such as seizures, and 20 cases involved ICU admissions, all related to the AstraZeneca vaccine. Of all adverse reaction reports, 11,413 cases (98.3%) were mild cases commonly occurring after vaccination, such as muscle pain, headache, fever, and nausea.
