So I would encourage the Minister to think about whether or not theirs is necessary—almost like a third way, a third pathway for the approval of medicines that for proven patent medicines, that for provisional experimental medicines, which section 23 was designed to cover, and then a third class now for the perpetual approval of things like influenza and COVID vaccines, because I think we're going to be doing this for years. And if the virus is going to act in the way that we think it is—it's going to mutate, it's going to need a new vaccine, we're probably going to need booster injections in a couple of years—I worry that if the authorities felt that it was necessary for Pfizer to do a full application on this, they now don't need to do that. Well, one could argue that by the time that's complete, a new provisional approval will be necessary for a new vaccine.
