Is it possible that x years from now x number of adverse conditions and/or deaths could be linked back to covid vaccines? Of course, anything is possible.
However, and believe me I'd have preferred not to have the vaccine in an ideal world, what exactly was/is the alternative to those saying we shouldn't have gone down this route? Unless you think the whole covid thing is a bit of a scam (please explain the deaths if that's the case) if the masses had said 'no' to vaccines and staying at home, distancing etc, the deaths could have been millions more by now. So surely vaccines are the lesser of greater risks, no?
Also, consider this. Unless you live off-grid and only eat your own home grown food and buy virtually nothing from retailers, you are exposed to multiple different chemicals daily. Yes they're deemed 'safe' by various agencies however we don't really know what the long term effects are. Whether through; food you ingest that has been sprayed with chemicals; food that's been processed in various ways; chemicals you use to keep yourself and clothes smelling nice; medications you take; smelling vehicle exhaust fumes; spraying your garden with weed killer etc etc.
My point is, if we want to avoid things that are potentially dangerous for us, how do we realistically live day to day? Yes of course we can reduce our exposure, but still. And surely there's an upside to vaccines e.g. the ones children get to avoid them contracting various illnesses that used to be a blight on many.
I'll be honest with you and I mentioned this in another thread. If I was fortunate enough to live in a secluded house and didn't have to go out (e.g. millionaire) I very likely wouldn't have had the vaccine as I'd be happy enough living as a modern day hermit, with my luxuries of course! However for most of us, that's not our reality. We need to socially interact. So, on balance, surely getting vaccinated makes sense?
