Boy, talk about "framing".
You are, as you often do, presenting the issue in a highly distorted way.
The reality, I suggest is this: there is a pandemic raging. There are variants arising, some clearly more transmissible and more dangerous. Covid is highly contagious. The fewer people who get vaccinated, the more risk to rest of us as these variants are fuelled by those who refuse vaccination. In short, the anti-vaxxers presents a very real and present danger to all of humanity.
Now then: having laid out the facts that you artfully concealed, let us then revisit your question:
What consequences do you think a person should face for being cautious about what substances they have injected into their body after hearing of other people being seriously injured or even dying after they received the same substance?
Answer: They should be subjected to crushing social pressure to stop putting exagerated fears ahead of their responsibility to behave as responsible citizens.
As another poster has stated: I am all for shaming the anti-vaxxer.
