People in democratic countries, the UK, Australia, Canada, the US at the very least, have been embracing vaccines in the
majority since the days of peak polio.
Throughout that time the majority have been aware that vaccines are there for the major risks location by location .. some vaccines are only useful if you're travelling to an equatorial hotspot for example.
Vaccine hesitancy hasn't come about because of democratic thinking, it's grown
* because anti vaxxers have had the means to amplify their message via social media,
* because fear of COVID created a fertile ground for that message ... AND
* a small group of quack medicine grifters put a substantial amount of effort into creating almost all the ground zero anti vaccine memes, messages, misleading statistics, "just asking" thought lines etc.
