Masks Have Made No Meaningful Difference to Delta – Oxford Professor

Professor Jim Naismith, Director of the Rosalind Franklin Institute and Professor of Structural Biology at the University of Oxford, has pointed out that, despite England dropping its mask mandate in July while Scotland kept its one in force, there is no evidence of this policy making any difference in the two countries’ infection rates. He writes:

The ONS survey results on prevalence shows that the Scottish and English approach to masking, although formally different since July, has made no meaningful difference to Delta. In both countries very high levels of prevalence have continued for months. Thus the new changes announced are unlikely to have much of an impact if Omicron does indeed spread rapidly.

You can see the ONS graphs below for yourself, and he’s right. Yet the Government has re-imposed masks in schools, shops and on public transport, despite there being no evidence that they make any significant impact on the spread of disease.
