It wasn’t when they were first rolled out. But we now have seen people sire and bear children after being vaccinated. We’ve seen a remarkably low rate of adverse side effects, honestly. And they work pretty well.
Not unreasonable, maybe, but uninformed. Once you know how mRNA works (whether produced by the body or introduced by the vaccine), it’s pretty hard to believe the vaccine could cause long-term problems.
I agree. It has been getting steadily less reasonable by the day. I am the only person I know who initially said, “Yeah, I’m worried about this” then at a later time said, “Ok, that’s enough time, it’s no longer reasonable to be worried.”
On the other hand, the number of ‘people I know’ has shrunk drastically in the last two years.
I mean, maybe. Like I said, learning more about the technology went a long way toward allaying my fears. But the human body is complicated. Medicine and immunity is complicated. We don’t know what we don’t know until we learn it.
You must be really terrified of getting on a bicycle. Physicists still can’t explain exactly why it stays upright.
Well, i looked at the likely rollout priorities, and i said, "I’m not sure I’d be comfortable to take it as a medical professional at the front of the line, but by the time i am eligible, i expect I’ll be eager. And that proved to be true. I jumped the line by looking for “extra doses” and finding one.
You’re kidding, right? The physics of bicycles are well understood, and gyroscopic stabilization is used in lots of other contexts.
But i did look up the theory of nRNA vaccination and i thought, “wow, that’s a really good idea. That ought to be pretty safe.”
If the bicycle were invented today, I’d probably wait a prudent length of time before getting on one, yes.
As it is, I always wear a helmet when riding because after decades of trials it turns out that’s a good idea. A bicycle can cause long-term harm.
I suspect @Mighty_Mouse was kidding, but you have it wrong as well:

Anyway, back to the topic at hand, not all the vaccines are mRNA – in the US, the J&J vaccine isn’t, if anyone is worried about the mRNA ones.
But the mRNA vaccines were the ones that were a brand new technology that had never been used before, even in an animal vaccine. So those are the ones i wanted to better understand.
And “the physics of bicycles are well understood” is true, regardless of the precise details. That’s why I asked Mighty_Mouse if he was kidding. It just seemed like a really weird thing to drop into a discussion of vaccines.
The thing that bothered me about people questioning the safety of “these new mRNA vaccines” was that the people I heard posing the questions were people who couldn’t spell RNA, not microbiologists.
I would probably have used the false claim that scientists don’t know how bumblebee’s fly.
A video from Veritasium 8 months ago went through the various theories on how bicycles stay upright, and the experiments that show none of them is a full explanation:

It’s possible the puzzle has been solved since 2016, or it’s possible all these articles are wrong, but the idea that bicycles are not well-understood is not bumblebee-flight level of myth.
Post hoc ergo propter hoc
Lots of vaccines caused and still cause long term negative side-effects. Vaccines before about the 1980s had higher rates of this than modern vaccines. But I think most well-established / regularly used vaccines in modern times can cause long term effects as well. Note however that even ones with particularly high rates of this–for example the smallpox vaccine (which likely would not have been approved for a less serious disease, because of the number and severity of side effects), these were “very rare” outcomes. Note also this is not different than virtually every type and form of medicine used in human medicine, and it is both weird and unusual and the product of generations of weird conspiracy thinking on vaccines that vaccines are looked at any differently in this regard.
You put some sort of compound in your body, it is likely that in some small number of people, it causes an adverse reaction. Some percentage of those adverse reactions will be serious, some fatal. With vaccines the percentages of those serious adverse reactions are very low. While it can take several years to fully research claims of adverse reactions, so far, we have seen no evidence suggesting the covid vaccines are causing a particularly serious number of adverse reactions.
Now what is basically unheard of is what is being suggested by covid anti-vaxxers–vaccinations that cause adverse long term reactions months after the injection. I’m not sure there’s like any cases in the medical literature of anything like that, for any vaccine in the last 30+ years. I’d be happy/interested to see any evidence otherwise.
Vaccines if they are going to cause an adverse reaction, it usually happens rapidly (within 15 minutes for allergic reactions, within 48-72 hours for other types of adverse reactions), and any ensuing long-term effects will be consequent to the initial serious adverse reaction. They don’t appear months later in someone who had no initial adverse reactions to the vaccine.
Bicycles stay upright because people are generally good at balancing. Put someone with balance issues on a bicycle and watch out!
And yet, roll a bicycle on a smooth surface and it will self-balance. So that’s not the whole story.

The issue wasn’t long term side effects, which definitely happen. In rare cases, like dying. The complaint was that we don’t see the impact now, but in seven years people who got vaccinated will suddenly get sick. That has never happened for any vaccine.
I mention that in the post of mine that you’re quoting.
I don’t believe that bicycles stay upright, that’s just a lie from big-Schwinn.
