If there's action by an adversary to try and weaponize naturally occurring disease (never mind the prospect of trying to heighten effectiveness of artificially created disease), that would be expected.

Vaccines and healthcare in general are intended as a safeguard against pandemics and mass death. If the goal IS mass death, it makes practical sense to try and delete all health and vaccine information in hopes it's lost forever and the society that uses it is rendered helpless against such events or weapons.

I'm interested to note that HN's commentariat hasn't mentioned the extent to which all scientific research of this nature was immediately defunded: my social media had indirect exposure to a lot of healthcare researchers who were freaking out, many days ago. Did you notice that part or is this the first sign of it that's made its way over here?

I'd note that defunding medicine isn't strictly HN-type content, though mass deletion of data certainly seems to be HN-adjacent. I would think hackers and entrepreneurs would take that sort of thing personally, as it more or less attacks them by starving them of information that could be useful.
