this variant. now, an important thing which we have said previously with other bits of immunity with viruses is that it is easier for the viruses is that it is easier for the virus to achieve ability to escape for infection than it is to achieve escape for severe disease and then on to mortality. so there is a reasonable chance, but i want to be clear, we need to wait until we have data before we can say this with any certainty, that even if there is some, ora certainty, that even if there is some, or a significant, certainty, that even if there is some, ora significant, escape certainty, that even if there is some, or a significant, escape from the ability to infect someone, and therefore for them to be infectious, it may be that there are still vaccines, in particular when they have had boosters, and natural infection boosted by vaccination, may be sufficient to go on to prevent people from going on to have severe disease, and in some cases dying. so that is the reason that the prime
