他的原话

A likely scenario is that there will be likely a need for a third dose, somewhere between six and 12 months and then from there, there will be an annual revaccination, but all of that needs to be confirmed. And again, the variants will play a key role.

保护力持续数年本身就是忽悠，保护力如果能量化，只要不是0那都算有保护力。用一个四周的extrapolation来猜几年效果。

靠，在这之前nature在我心中可是神一般的刊物。
