Now, my questions are—and the select committee really need to drill into this—what happens if the dose changes in its configuration? As the virus changes, the vaccine may need to change. If the vaccine changes, another consent should be sought. My reading of this amendment to the Medicines Act is that that won't be necessary, and if—and I must stress that I don't think there is any material chance that this will happen—a fourth dose was harmful, who is liable? Well, not Pfizer, because Pfizer have made it very clear that they didn't apply for consent for a fourth dose. They weren't sure of the benefits, and I'm quite sure they don't think there's any real risk, but what if there is? What if there is harm—who is responsible? It won't be Pfizer.
