There are many counter-arguments that can be made to your post. For example:
1 - You're suggesting the vaccine poses a risk to healthy individuals who are at very low risk of dying from COVID, we would also have to compare the health of people dying after the vaccination - is it only killing the incredibly vulnerable? If that's the case then someone like myself as a healthy individual has little to fear? This would essentially make your point redundant.
2 - The probability that 'everyone has already had COVID twice' is close to 0. There's no evidence to support this, and even if we'd all had it twice (which we haven't) then there's clearly an issue with subsequent contaminations that hopefully a vaccine can help us avoid.
3 - The vaccine rollout is literally costing our Government billions. We're also haemorrhaging money whilst the country stays in lockdown. There is no financial incentive, other than the re-start of the economy. Also, the majority of 'the chemical companies' investment was paid for by the UK government (in AstraZeneca's case anyway).
I think it's good for people to be sceptical and to question things. But at least base your arguments on solid facts rather than trying to spread fake news.
