I am not sure how helpful strawman logical fallacies are in debates.
From what research I've done, the Barington declaration seems to be based on ideology rather than science.
“We do not know yet how long immunity will last, so achieving herd immunity may not be simple. We do not have herd immunity to the common cold despite many of us having one or more each year. It would have helped had the leading scientists who signed this declaration estimated achievability of herd immunity with different immune response decays.
“The desired range for herd immunity is not stated nor how far away we are from it, thus no estimate of the number of deaths or the life changing complications that will result in the lower vulnerability group is made. Whilst these numbers are much lower than in the elderly, they are not zero. I suspect the public would like to know this.
“A working description of vulnerability is not given, the Goldacre paper in Nature assigned probabilities, what is the personal score threshold being advocated?
“From a public health point of view, it would have been useful to estimate the gains with different assumptions of the timing of the arrival of the vaccine.
