For the first time, a national research group analyzed a symptom called "moderna arm," in which the arm turns red after a while after vaccination with the new corona virus vaccine.
On the 9th day after the inoculation, 3.5% of the people had symptoms, and the research group said, "I want you to take measures such as cooling your arms."
People who have been vaccinated with the modelna vaccine may have redness or itching on the arm inoculation site for more than a week, and it is also called "moderna arm" overseas.
A research group of the Ministry of Health, Labor and Welfare analyzed the symptoms of 1447 SDF personnel who received the first vaccination for the first time after the 9th day after the vaccination.
As a result, 3.5% of the respondents had red arms on the 9th day, 4% on the 10th day, and 2.6% after the 11th day.
Those who had itchy arms were 2.7% on the 9th day after inoculation, 2.4% on the 10th day, and 1.3% after the 11th day.
Some people had symptoms until the 25th day, and the onset was noticeable in people in their 40s.
Suminobu Ito, a visiting professor at Juntendo University School of Medicine, who is the representative of the national research group, said, "Some people have symptoms again after they have subsided. I want you to respond by doing so. "
"Moderna Arm" Who actually had symptoms
A woman in her 40s who received her first vaccination with Moderna on the 28th of last month noticed redness and itching at the site she received on the 8th day after vaccination.
From that day to the next day, the itch became worse, and after dealing with it by cooling it or applying a medicine to suppress it, the symptoms finally began to subside on the 12th day.
A man in his thirties who received the first vaccination on the 29th of last month began to turn red around the 10th day. On the 12th day, itching also appeared, and the redness became about 6 cm in diameter.
