Because the entire subject is so politicised and polarised that even daring to ask a question that might go against the current might get you labeled as a right wing science denier racist (based on the country, different labels might apply).
Edit: it's funny that the comment above gets downvoted just for asking a question. Great world we live in. We didn't learn anything from the past. Blaming and shaming gay people in the AIDS epidemic, some previous hastily released vaccines that caused the anti vaccine current to gain momentum (just look in the nordics at the current willingness to get a COVID vaccine, something like 1 in 4 maybe)
Yes, and this is a serious problem. It seems to be one camp or the other, blind fear or blind approval, with little room for thought.
I honestly hate anti-vaxxers with incredible intensity now. Before they were an annoyance, now they have destroyed all intelligent discourse on this current topic.
For logical concerns, another example is an earlier, mouse brain derived Japanese encephalitis vaccine. Pulled, due to suspected prions causing brain swelling, and death. It should be noted that these effects were not seen until years after a peron received vaccination.
It does not matter that current vaccine $x does not "work that way", instead, it is well known that some vaccines will be troublesome.
This is not anti-vaxxer, I have all standard vaccinations, for they are tested, years of use behind them, safer than the alterative.
Yet it is so hard to find accurate info, everything is filled with crazy, emotionally based screaming and decision making, it's infuriating.
To expand a bit on that comment, 46% said that they would take the vaccine while 26% said that they wouldn't. The numbers in August were 36% and 37% respectively.
