earlier i spoke to linda bauld, professor of public health at the university of edinburgh and got her is actually the week before any of those changes happen with the easing of restrictions that it showed us what occurred due to the easing subsequent from the middle of may and what we are seeing is a rapid rise of infection in the community and there is a large reservoir, still, of the community who are able to pick up this virus and transfer it without the protection of vaccination and i keep hearing a couple of things. we know that the link is weakened in terms of the connection between covid—19 and positive cases going into hospital and mortality but it is still there and other indicators have been rising as well, just because there are so many people infected in the community. the final point i would make on that as we are seeing up here in scotland and i would suspect elsewhere in the uk that because there is so much infection and the vaccines are not 100% protective we are actually seeing an increase in the proportion of older, vulnerable adults in hospital with covid—19 and tha

linda bauld, professor of public health at the university of edinburgh, explained why scientists areinged, i think, in the last week is very, very disruptive with the covid—19 app, so the business concerns are absolutely real nd i think there needs to be a solution. and if you look around the world atother countries that are doing well in their vaccine programme, singapore, for example, they are also moving to a system of not requiring self isolation for people who've had both doses of the vaccine. but i guess the question is why is it not being expanded instantly? and i know you've been covering that on the programme. there are a couple of public health reasons for that and then there are practical reasons. the public health reasons are that vaccines do not prevent transmission. we know that. we don't have good data on transmission yet, but we know that people who have been double vaccinated can still pick up the virus and they can still pass it on, and some of them will still become unwell, if not severely. so you really want to try and reduce that risk, particularly at the current
