My noble friend puts it very well. Clearly, with the infection rates rising but with a very large proportion of the country vaccinated, it is worth reviewing this. As the Secretary of State said in his Statement earlier this afternoon, from 16 August the Government intend to exempt people who have been fully vaccinated from the requirement to self-isolate if they are a contact of a positive case, with a similar exemption for under-18s. Anyone who tests positive will still need to self-isolate regardless of their vaccination status. Symptomatic testing will continue to be available. This is a proportionate direction, given the state that we are in.
