Elon Musk: @peters8620 @stillgray @ScottAdamsSays 在疫苗问世之前我有 OG C19，基本上是轻度感冒。 然后打了强生疫苗，没有任何不良影响，除了我的手臂短暂受伤。 第一个 mRNA 助推器还可以，但第二个让我崩溃了。

原推：@peters8620 @stillgray @ScottAdamsSays I had OG C19 before vaccines came out and it was basically a mild cold.

Then had J&J vaccine with no bad effects, except my arm hurt briefly.

First mRNA booster was ok, but the second one crushed me.
