Because Boris Johnson has made a big thing about all the steps being irreversible, I think he’s put himself in a position where once he takes a step, he’ll be extremely reluctant to reverse because that would be a big U-turn, an embarrassing climbdown.
So I think if that’s the way you’re going to play things, then you should be very, very cautious about every step you take … And maybe everything [will] be OK, maybe the number of people who are vaccinated will be just enough … ‘R’ will broadly speaking stay below one even with Indian variants.
But if it’s not OK, we know, because of mathematics, that things will get bad very, very quickly. Or at least, maybe it won’t look that quick to start with, but it’ll grow exponentially. So it’ll pick up speed and become a big problem.
