You’re correct, no evidence at the time JCVI (joint committee for vaccination and immunisation) made the call. However the decision was made on best interests [1] from a public health perspective. Delaying to 12 weeks allowed absolute numbers of people to be immunised once and build up some immunity versus absolute numbers of people vaccinated twice and having higher number of vulnerable populations without any immunity. Of course, this wasn’t taking into the people who had had COVID-19 and had a level of immunity to the virus from exposure.

This isn't true, the JCVI did have evidence. In fact their statement showing reasons behind the call said:

"There is evidence that a longer interval between the first and second doses promotes a stronger immune response with the AstraZeneca vaccine."
