Yet people like this who just don't want to inject anything that hasn't been studied for at least a couple of years, don't coach our opinions in anti-vaxx language. Stuff like "new species" is ridiculous and masks the actual rise of surveillance totalitarianism which uses Covid as an excuse.
Most people I know are pro-vax, have all their other vaccinations, but are leery of new technology being distributed under the same label. I think that's reasonable. I'm one of these people. I don't plan on taking any mRNA vaccine until we have a few decades worth of safety data on LNPs, although I think the technology and its development is very interesting. [1]
Does the net health benefit provided by mRNA vaccines probably outweigh the consequences of Covid? Probably, even almost certainly. But I'll stick to more conventional biotech for now.
In general, I think the average person hugely overestimates how much we know about biology and how much experts really know - they know 100x more than me, but still 0.00001% of what there is to know. We have a lot of hubris when it comes to science and technology.
