Yes, and there are people that have developed long haul type issues after getting the vaccine. It’s just not published. As one of those people put it - “they don’t want to see us.” FB took down a page where some were sharing their experiences. Why did FB do that?
Downplaying risks is not helping make reluctant people feel more comfortable about it. It just makes them even more suspicious. They are thinking - I now know some information is being hidden, why and what else don’t we know? Many of them already don’t trust the media, the government, politicians in general, or the ever-changing, in their view often illogical, guidance. Some closer to the fence may ultimately decide they are ready but want more information and some of that requires more time.
Maybe that’s another difference with polio. Maybe back then more people had more trust in the “system”.
People who don’t want the vaccine are aware of health issues from Covid, they just feel that their odds of that don’t outweigh their discomfort with the vaccine. It’s a pick your poison, the devil you know a little or the devil you know even less issue for them.
Remember, they are not as afraid of COVID as the people who couldn’t wait to get the vaccine. Many have been going about their lives, sometimes without masks, for a year. People are in different places on the COVID is Contagion or a Cold continuum. Some people can accept people being in different places and others can’t. It is sad to see it driving people apart.
OP originally asked what can people do to convince the reluctant. I just see “yah buts,” and “they need to be forced” arguments.
Based on what I see and hear, if the pro-vax people want to change the opinions of non-vax people, they will need to change their approaches. Current approaches don’t seem to be moving the needle any further. Has anyone asked them what it would take for them to agree to get the vaccine?
In my purple state where all 16+ have been eligible, a little < 50% of the eligible have gotten 1st dose and there are plenty of unfilled empty appointment slots available, which indicates the people who want vax have already gotten it and vax/not vax split is pretty even. We are not looking at a situation of just isolated hold outs. It also suggests that the opinions on CC, which tend to lean pro-vax, are not necssarily reflective of the general population (that or the not-vax people on CC are mostly keeping quiet).
