My Lords, I do not quite agree with the premise of the question, which is the concept of being partially vaccinated. When you get your first vaccination shot, you are vaccinated, your body has been primed, B cells make the antibodies and you learn how to fight the disease. That is categoric. Where the noble Baroness absolutely has a point is that it is an uncomfortable truth that when we lean in to the virus, it will seek to escape and mutate, and that is the moment of absolute highest risk for the country. That is why we are trying to move as quickly as we humanly and possibly can: there is a moment in time, an opportunity to get the vaccine out to as many people as possible to avoid the mutation throwing up variants that escape our vaccine.
