With regards to the reduction in the gap between vaccines. I would worry that contrary to new evidence in trials, shorter gaps have now been demonstrated to be less effective. Indeed, the longer the gap, the better. Of course, as with all these things, it is a balancing act to getting everyone double jabbed asap. However, as we see in Israel, does the shorter gap subsequently require a booster, would a longer gap negate that, what is the consequence of leaving longer gaps versus infection control. I actually don't envy those who will have to make this decision.
