I don't regret it at all, no.
Far less likely to have any problems from the vaccine than from Covid.
I think people are afraid because they feel that they have more control over whether they get Covid or not - but that's a bit of a false sense of control. Clearly you do have some element of control, but a lot of it will come down to bad luck and lots of other things you can't control. So the risk is still there, however much you think you are mitigating it. Vaccines feel a bit like the opposite - you feel like you have deliberately exposed yourself to it, so the risk feels a lot worse, somehow. But overall, really, your risk of catching and having complications from Covid is likely a lot higher than anything happening from the vaccine.
Governments like Canada who have lots of other vaccines to choose from will end up being cautious because they can, and if there is even the slightly hint that there could be a connection, they can pause the vaccine without it causing a huge problem. It doesn't mean that they think it's unsafe. It's just that if nobody knows if there is even the slightest connection, they can pause the rollout of that one for now.
If people are worried about having the vaccine, they'd actually do better not to say that on social media, because their situation would be best if everyone else had the vaccine but them! I always think it's a bit odd for people to talk about not having vaccines, because that puts other people off, making the world less safe for them.
I think there is also an element of people expecting bad side effects, and then noticing every little odd thing that happens to their bodies, in a way that they wouldn't if they hadn't just had a vaccine. The odd itch on my foot, or a slightly annoying ache, or tired eyes, or whatever I might have just ignored most of the time, suddenly seems bigger and more important if I think about just having had a vaccine. I'm not saying it's the case for most side effects - obviously there are very real and difficult effects - but there is a sort of heightened perception of any little sensation right now, for all of us. Moreover, you really don't hear much online from the millions and millions of people who have had no issue whatsoever from this vaccine, nor from those who had side effects from other vaccines, so all our attention gets directed to this vaccine as being the most problematic, when it's likely more balanced than that.
And it isn't to do with it being rushed. All vaccines and new drugs will eventually be rolled out to millions and millions of people, and very rare reactions will occur - they are only ever trialled on smaller populations, so there is no way that these 1 in several millions risk reactions will all have shown up in the trial stage. It just seems faster this time because we have got to the stage of having given many millions of vaccines much sooner than normal. They weren't tested less than usual, it's just that all that testing was completed in a more condensed period of time. But the rare side effects only show up once a large number of the drugs/vaccines have been used, regardless of the timescale.
