摘抄其中的部分
The most comprehensive study to date was a large study in children aged 5-17 years with mild COVID from the United Kingdom. Of 1,734 children, 4.4% reported persistent symptoms 28 days after the start of their illness.
In these children, the number of symptoms at 28 days was fewer compared to that in the first week of their illness.
The study found 1.8% of children has symptoms at day 56. Headache, fatigue and loss of smell were the main issues.
Three-quarters of the children with persistent symptoms went on to report a full recovery. However, a quarter were not followed up, so it was unclear how many among this small group may have had longer-term problems.
The same study observed children who had other viral illnesses, not COVID. It found 0.9% showed persistent symptoms at 28 days. This suggests a “background rate” of non-specific symptoms like headache and fatigue occurs in children, which is important to consider — although the rate in children following COVID was considerably greater.
就是说5-17岁的 4周28天后有4.4%还有症状 1.8的在8周后还有症状。主要是头疼 疲劳和嗅觉丧失。
四分之三的报告完全恢复 。有四分之一的未跟进，所以不清楚剩下的里面还有多少有问题。
对于其他有病毒性疾病的孩子 在28天后有0.9%的还有症状。 所以可能小孩中就是会有这么高的比例出现像头疼和疲劳这样不显眼的症状

1/4*1.8%=0.45% 基本上就是说最多 0.45 的新冠后遗症不能完全恢复吧
不过这个病程太长了 基本上超过4周后 家长就会更加担心

现在的问题是疫苗已经不防感染了
太多BREAK THROUGH CASES
打不打，对孩子来说，区别大吗？

这篇的思路还算比较严谨的

所以对于低龄儿童，青少年，
是打疫苗的后遗症多，
还是
裸奔被感染的后遗症 多？

短期来看，有报道说疫苗心肌炎比例比COVID更高。但又有报道，小孩1/10有LONG COVID副作用
长期来看，WHO KNOWS！

十分之一这个有出处么？感觉不太合理

这篇文章不单指小孩，就是说康复后，新冠病毒可能还会藏在大脑里，免疫力下降时会重新激活。（但估计1-2天的轻症应该不会有事）
类似的有带状疱疹是由水痘病毒重新激活引起的皮疹。但新冠和水痘 的位置不同…
