Is this comment about UK decision to give boosters after 3 months from last vaccination?

I think there is big misconception about boosters and Delta. People appear to assume that there is some time after what vaccines loose effectiveness against Delta.

I see it rather as assumption that 1 shot should work against Wuhan variant. Well, it does not so does not 2 shots against Delta. Waiting period is irrelevant. It is only a compromise between mounting a better immune response from time difference and risk of infection.
