Why not? We kinda already did it for the flu every year. And if it is the only alternative to lockdowns [1], I think most of us would prefer that.

Side-note: The article quotes Fauci as saying "I think it's too premature to be talking about a fourth dose...". That seems like one of his "noble equivocations" to me. If Israelis do need a fourth dose, it is probably true that so do Americans.

[1]: And we don't discover any long-term side-effects for the vaccines, which seems unlikely.
