Well here is a simple concern that I have with regards to where a "slippery slope" could lead. It is that there will be a push for people who do not need to be vaccinated with covid vaccines to be coerced or mandated into having them.
For example covid recovered persons.
This is already happening.
Generally in medecine it is widely accepted that it is neither ethical nor good practice to administer unnecessary medecins. Zero risk does not exist so unnecessary drugs, vaccines, procedures, etc are considered unethical and in disregard of the risk benefit ratio principle. IMO mandatory covid vaccination also flouts the hippocratic oath.
So we are already sliding down the slippery slope.
And that's before we start talking about people losing their jobs if they refuse pharmaceuticals that they do not need.
I live in a country which has vaccine passports and it is becoming increasingly difficult for covid recovered people to live normal lives without accepting injections that they do not need.
There are plans in Greece to fine unvaccinated people whether they need the vaccine or not.
If covid vaccines become mandatory many millions of recovered people who do not need to be injected with them may be denied access to education, childcare, means of earning a living.
It is UNBELIEVABLE how close we are in some places to the above.
Things that we would never have accepted 3 years are already happening and the door is wide open for much more.
And the context that this is happening in is nothing like the context of smallpox. It is happening in the digital era where it is very easy to restrict people.
Personally I think requiring people to accept a 3rd (and probably more) injections in order to retain "acceptable" status is both on the cards and very problematic.
So even just on the above without discussing the vaccination of children or the bizarre controversy around prophylactic treatments I think we are already well on the slippery slope that you talk about.
I don't know what will potentially be next. More vaccines? A controversy over the volume of adverse events from covid injections?
These things are already in the pipeline.
