I think this is in part a consequence of successive governments’ conflation of science and innovation.
They’re related, to be sure. But a science policy is not an innovation policy, and an innovation policy is not a science policy.

I wonder the extent to which formal public health recognition of the link between common viral infections and dementia/AD is being held back by the regulatory obligation it creates for things like clean indoor air and managing risk of infections we currently view as relatively benign annoyances.
I was fine after getting both shingles shots, although my husband had flu-like symptoms after each of the 2 doses. Still, that seems a small price to pay to reduce your dementia risk.
