Pfizer's vaccine has been vaccinated to domestic healthcare workers since February, and according to the Ministry of Health, Labor and Welfare, 1,096,698 times have been vaccinated by the 4th of this month.
The Ministry of Health, Labor and Welfare revealed at an expert group meeting held on the 9th that 79 cases corresponded to anaphylaxis as a result of analyzing post-vaccination symptoms reported by medical institutions using international indicators.
In terms of frequency, it is 1 in 13,882 times, which means that almost everyone is improving.
It was also reported that a total of 6 people in their 20s to 70s who had been vaccinated had died after vaccination.
The causes of death were four hemorrhagic strokes and one acute heart failure and one drowning, and PMDA (Pharmaceuticals and Medical Devices Agency), which examines drugs, says that the causal relationship with vaccination cannot be evaluated.
In response to this, the expert group reiterated the view that "there are no serious concerns about the safety of the vaccine," and will continue to analyze the post-vaccination symptoms of the elderly who will start vaccination on the 12th of this month. I am doing it.
