Covid-19

My Lords, this is the clinical advice given to us by clinicians. I cannot answer the whole question in the round in this brief session, but a number of considerations include not only that vaccines offer a significantly reduced rate of infection but that the level of infection is much lower, the viral load is much lower, and therefore the infectiousness is much lower. The aggregate effect is that a group of people who have been vaccinated, with a few who have the disease, is less infectious than a group of people who have been tested, however good the test.
