'The first double-blinded randomised clinical trial to test the effectiveness of antivirals against dementia is now under way.

Oh wow, a bunch of Alzheimer’s grants at Columbia were canceled, including the Alzheimer’s Disease Research Center. Unclear if this study was affected…
So... and unfinished RCT of an unrelated drug an a project to start in the future a RCT of this new use of the vaccine.
The problem is mixing the real protection of the vaccine against shingles that has been tested in RTC and new aplications that have not been tested enough.
If there are too many false provisional anouncements, people will not thrust medicine.
The article opens describing how people vaccinated against the HSV1 virus are statistically less likely to develop dementia, and that a newer virus appears to confer an even bigger effect.
The article then proceeds on the history of the scientific debate on whether the HSV1 virus has a causal link to Alzheimer's and the level of acceptance of the hypothesis.
Finally, the article concludes describing how an RCT is taking place to find whether an antiviral which is used to treat HSV1 has an effect on the development of dementia.
It all ties together with the theme of the article, which is about the possibility that viruses may trigger Alzheimer's and the reason why research is being carried out in that direction. That open question is literally expressed in the headline.
I honestly cannot understand the problem you are seeing in the article. How else would you express the same information?
