搬自文学城。 One of the four factors researchers identified is the level of coronavirus RNA in the blood early in the infection, an indicator of viral load. 和我观察到的一样，感染后有没有症状，症状轻重与viral load成正相关。 Another is the presence of certain autoantibodies — antibodies that mistakenly attack tissues in the body as they do in conditions like lupus and rheumatoid arthritis. 就是有没有产生抗自身抗体。不仅病毒可能会导致这种抗体产生，疫苗同样也会。这就是我担心的疫苗的远期副作用。 A third factor is the reactivation of Epstein-Barr virus, a virus that infects most people, often when they are young, and then usually becomes dormant. The final factor is having Type 2 diabetes. 最后这两个不了解。 纽时原文：https://www.nytimes.com/2022/01/25/health/long-covid-risk-factors.html cell 原文：https://www.cell.com/cell/fulltext/S0092-8674(22)00072-1#relatedArticles

应该是因为第一点，降低了viral load。所谓疫苗防重症，也应该是同样的原因。
