as it is to technical medical advance

[GoodTaste]

200 years isn’t a milestone. It is only a brief moment in the long and erratic history of human endeavour. Much of what we call progress in health is as much due to increasing prosperity and wider educational opportunity, as it is to technical medical advance. But the importance of health as an idea in society lies beyond the immediate materiality of bodily wellbeing.

I wonder whether there is a comma "," missing between "technical" and "medical" above.

No. That's not possible, because there's no "and" linking the two.
