did you read the link i provided? in case the implication wasn’t clear i’ll say it explicitly. Viruses which are virtually nonexistent (not circulating in the population) can be induced in a population by vaccination itself (in rare cases when using an attenuated virus).
This means there is a risk, especially for viruses like polio which basically don’t exist anymore, that a vaccination program will generate polio cases which then spread and create a new outbreak of polio.
Those recent outbreaks of polio were thought to be from an unnecessarily aggressive vaccination program, at least that’s the reporting i encountered.
I haven’t done a risk calculation, i don’t claim to be an epidemiologist or to know at what point this exotic risk outweighs the benefit of herd immunity. I suspect that calculation depends on things like exposure points in the population, general immunity, and the %of people already vaccinated historically.
It’s definitely a real effect (i linked directly to the american CDC) and it should be included in any discussion concerning virtually dead viruses. It hasn’t been made up by ‘antivaccers’ and for me personally i don’t even bring this up in those kind of spaces because i don’t trust them to parse this level of nuance and contradiction to be brutally honest.
The risk profile probably varies virus to virus also.
the search providers (especially that famously ‘not evil’ one) had a huge hand in centralising and then gatekeeping access to ‘the web’. They have such a disproportionately powerful effect on how users discover content, and huge power to drive self-fulfilling ‘network effects’ where people go where people already are, which has become so normalised that most people couldn’t imagine ‘the web’ without them.
i’m not suggesting it was ever realistic or possible, but what we needed was for that one search provider and indexer of content to be broken up, partially nationalised, and partially integrated into the network specification itself. Only they are powerful enough to become a model for how to functionally disentangle their operations into public and private parts.
the only alternative is to break the centralisation of the web as china is doing and other BRICS nations intend to do, by creating ‘national internets’ which in some ways federate together and in other ways do not. I don’t like this model of development for the future of the internet but the security considerations of the present require this kind of approach.
