５～１１歳の発熱、低い傾向　ワクチン接種後の副反応調査―厚労省研究班・新型コロナ

　新型コロナウイルスワクチンを接種した５～１１歳の子供のうち、接種後に発熱したのは１割程度にとどまり、成人と比べて低い傾向が見られることが厚生労働省研究班（代表・伊藤澄信順天堂大特任教授）の調査で分かった。研究班の中間報告が１０日、厚労省専門部会で示された。
　調査はファイザー製ワクチンを接種した５～１１歳の１０６人を対象に実施。副反応が起きる割合などを調べた。
　その結果、２回接種後に健康状態の報告があった子供６２人のうち、３７．５度以上の発熱があったのは１１．３％だった。同社製を打った２０歳以上を対象にした調査では、２回目接種後の発熱は３８．１％に上っている。（2022/06/10-19:24）

Children aged 5-11 had a lower fever incidence than adults after the second COVID-19 vaccination, a health ministry survey revealed Friday.
   According to the study, 11.3 pct of such children had a fever of 37.5 degrees Celsius or higher after receiving the second dose of Pfizer Inc.'s vaccine, compared with the fever rate of 38.1 pct for those aged 20 or over.
   A team led by Suminobu Ito, professor at Juntendo University, conducted the side effect research covering 106 children aged 5-11 who finished getting the second shot of the Pfizer vaccine, the only approved coronavirus vaccine for children in the age group in the country. Of them, 62 gave responses.
   The team also found that 22.6 pct of the children felt fatigue and 14.5 pct had headaches. These figures are much lower than adults' 68.8 pct and 53.1 pct, respectively.
   No severe side effects were observed among the children.
