What are "old worries"? This is a new type of vaccine.
> They have a lot of data from previous forms of this type of things suggesting it is safe.
How does this make sense, given this is the first mRNA vaccine? The expression "previous forms of this type of things" is as blurry as it can get.
> We know the that injected "things" break down very quickly in the body, which again makes us believe there won't be any long term problems.
Heavy metals are "things", and when you inject them in the body, they don't break down, but stay there and slowly kill you.
> Of course in the end who knows. There could be something, and we may not know for 10 years.
This is not the attitude I'd take on something that potentially hundreds of millions of people will be subjected to. I'm aware that you can't ever prove something to be safe. I want to know if the specific risk brought about by mRNA vaccines are well understood or not, and why.
> On the other hand, we know that Covid is killing a large number of people right now.
It doesn't.
> We have enough data to confidently state that the long term adverse effects are overall less bad than Covid.
Splendid, I'm not going to ask for sources then, because I like the tone of your voice so much.
