It's down to time x distance:
Vallance:
“The risk at one metre is about 10 to 30 times higher than the risk at two metres, so social distancing is an important part of this.” “The evidence is, as far as you can get very firm evidence on this, is essentially a minute at two metres contact is about the same as six seconds at one metre." 5th May.
The time element is key, and something (as your link explains to you if you'd read it) that was omitted from the Lancet study:
"While the finding from the Lancet paper offer support for the current UK recommendation, it is important to recognise that the study had some limitations. For instance, the authors were unable to assess the effect of exposure duration since this factor varied considerably".
Interesting that you quote Vallance.
This Vallance scumbag on the need or otherwise of face masks. Typical of the vague BS analysis and advice that witch doctor and his fellow charlatan Whitty have handed out throughout this catastrophe they've overseen.
So Germany is making it compulsory to wear face masks...but the United Kingdom Banana Republic still wont advocate it because they're being led by the science...the science headed up by two discredited chuckle heads called Whitty and Vallance.
Whitty and Vallance need lynching. No question. Two nodding dogs.
