“We are analysing your feedback." This next step is exactly what MHRA says on its website: they are analysing the feedback.
That’s the step before publishing the final guideline and integrating it as an MHRA regulation.
I have always said, months ago already, that the guideline is not strictly required for approval, but MHRA clearly sees value in finishing their analysis before they move forward on precedent-setting cases like DCVax-L.
