@MattHitch @Craig_A_Spencer There is one that works, and others are in development.
But no telling what will work with a future variant (could be very different from Omicron and more like another variant), so should stockpile all of them.
@MattHitch@Craig_A_Spencer有一个有效，其他的正在开发中。
但不知道未来的变体（可能与Omicron非常不同，更像是另一个变体）会有什么效果，所以应该将它们全部储存起来。
