Saying that the virus is dangerous doesn't make the vaccine safe in the long term. You might be right, but you have no basis to suppose it's safe in the long run. You are just betting it because tv told you so.
> It's been proven non-poisonous hundreds of millions of times already.
You are talking about possible future unknown effects. No it hasn't been proven at all. They aren't even looking for possible long term damage.
Anyway they downplay it in the leaflet but its there: "The COVID-19 vaccine has gone through the same clinical trials and safety checks as all other licensed vaccines, however the vaccine is new and long-term side effect information is limited."
