I don't give credence to things I can't verify myself unless the source has proven to be highly trustworthy,
Sentiment has, over the many years here, always proven to be highly trustworthy. Also, your analysis is based on where the MHRA is, is based at an average workload based from other approvals. It is nice to know but does not necessarily mean anything for the DCVAXL approval process.
The DCVAXL trial got special attention from the MHRA because of its unusual setup. Therefore it took longer compared to the approval process of other similar medical trials.
