Science progresses, we are almost 70 years out from the the poliovirus vaccine and they've learned a lot. Perhaps you should explain in a few sentences exactly how an mRNA vaccine works? I can. I have knowledge and it gives me confidence, you appear to suffer from ignorance and that explains your fear. If you have evidence fine, but so far I've heard unfounded fears and paranoia, nothing to indicate a real issue. Perhaps you should list the corners cut? Procedures were telescoped, not cut, trials done in parallel, not sequentially as is normal when there is no rush.
Do you think these scientists and experts are fucking fools who don't know their business? They will all take their own medicine first, it doesn't get any better than that and the people asking you to risk your pink little ass for others will take the vaccine on TV long before you. These people are scientists and are disciplined by peers in what the say and do, they live by personal and scientific integrity, if you deal in information and you have no integrity you are useless and so is the information you generate or process.
If you wanna know why I feel strongly about this:
Look at Trump as an example of uselessness, he lies all the time, it makes him useless as a human being. Scientists are useful because they tell the truth, on rare occasions they commit scientific fraud and that can cause a lot of damage. A single case of scientific fraud that was confessed and disproven by multiple studies, founded the antivaccer movement. It's all they've got, one disproven and self confessed fraudulent scientific study and yet they've caused thousands of children to be murdered by their own parents who believe bullshit. Is it any wonder people with brains despise these ignorant assholes? Helping to murder innocent children has never been popular among decent people any where and any time.
