But initially, they thought the first jab gave sufficient protection until the second jab 12 weeks later. If you remember, the initial time between jabs was going to be three weeks (as this was what had been clinically tested), but the risk analysis was taken to extend this to twelve weeks to ensure more people got the first jab.
One jab gave reasonable protection against earlier variants, until you got the second jab - it doesn’t against the latest variant (hence the modifier of "strong" protection).
They’re now saying "get the second jab quicker to provide more protection sooner against the Indian Variant" - again, good science - re-evaluate and modify guidance when new information becomes available.
