While vaccination for a new coronavirus infection (Corona 19) in Korea is in full swing, more than 40 reports of adverse reactions after vaccination have risen.
The Corona 19 Vaccination Response Advocacy Team (the advocacy team) announced that 47 new cases were reported as adverse reactions after the Corona 19 vaccination at 0 o’clock on the 29th.
All recently reported cases are mild reactions such as muscle pain, headache, fever, chills, and nausea, which are common after vaccination.
There were no cases of suspected serious systemic allergic reactions such as “anaphylaxis” or serious adverse reactions.
There were no further reports of death.
So far, a total of 21 suspected cases of death have been reported. Previously, the advocacy team concluded that the analysis of the cause of death of 15 patients was not related to vaccination, and the causation of vaccination has not been confirmed for the remaining deaths.
As a result, since vaccination began on the 26th of last month, the number of suspected adverse reactions has risen to 10,347 cumulative.
This is the 1.29% level of the cumulative domestic inoculation of 79,198 (793,000,966 primary vaccinations and 5,232 secondary vaccinations).
By vaccine type, AstraZeneca vaccine-related cases accounted for 11.26 cases, representing 96.9% of all reports. 321 cases (3.1%) of adverse reactions related to the Pfizer vaccine were reported.
This appears to be due to the fact that the number of people who received the AstraZeneca vaccine (733,586 people) as a primary vaccination standard was much higher than those who received the Pfizer vaccine (63,380 people).
The adverse reaction reporting rate compared to inoculated is 1.37% for the AstraZeneca vaccine and 0.49% for the Pfizer vaccine.
In the case of adverse reactions reported so far, there are 101 suspected cases of anaphylaxis (89 cases of astrazeneca, 12 cases of Pfizer), of which 95 cases were anaphylactic reactions and 6 cases of anaphylactic shock.
Status of adverse reaction reports after vaccinationSuspected cases of anaphylaxis are largely divided into anaphylaxis, anaphylactic shock, and anaphylactic reactions.
The anaphylaxis-type reaction is a case in which dyspnea and hives appear within 2 hours after vaccination, and it is similar to anaphylaxis in terms of symptoms, but experts explain that it is not a big problem because it can be improve with symptomatic therapy.
After vaccination, there were 10 reports of serious adverse reactions. Of these, seven cases of nervous system reactions such as seizures and three cases of hospitalization in the intensive care unit were related to the AstraZeneca vaccine.
Additionally, 11,215 cases, accounting for 98.7% of all adverse reaction reports, were muscle pain, headache, fever, chills and nausea, which are common after vaccination, the advocacy team said.
Meanwhile, as a result of an analysis of the cases of suspected adverse reactions reported during a month from the 26th of last month to the 25th of this month, when the vaccination was started by the promotion team, 92% of all the cases occurred within two days of the vaccination date.
In 50% of all cases, adverse reactions occurred on the day of vaccination and 42% on the day after vaccination.
In addition, women (1.54%) had a higher adverse reaction reporting rate than men (0.76%), and the younger they were, the more adverse reactions reported.
Notification rates by age group are 3.18% among 20, 1.62% among 30, 1.1% among 40, 0.69% between 50 and 0.25% between 60 and over.
When looking at the cases reported by age, 45.0% in their 20s, 22.0% in their 30s, 15.8% in their 40s, 13.1% in their 50s, and 4.0% in their 60s or older.
By vaccination institution, the notification rate was 2.11% for medical institutions of hospital level or higher, 0.91% for nursing hospitals, 0.87% for nursing facilities, 0. 51% for first responders and 0.45% for corona treatment hospitals 19.
The advocacy team conducts a ‘Vaccination Harm Investigation Group’ meeting every Friday consisting of doctors and forensic experts to discuss the causal relationship between reports of serious adverse reactions such as death and vaccination.
