Nope... have a link?
I'd presume poison is poison whether you ingest it, or it gets injected. I was always taught even touching mercury absorbs it into your skin...so I don't see how ingesting it would be any less lethal than injecting it
Delivery systems are different. Which means how much one can tolerate within a given time are also different. Shots in a targeted area (say for instance pain killers) help localize the delivery site and help with the pain quicker compared to say taking a slow release pill that has to go through the digestive system and slowly be delivered to the targeted area. The delivery does is not going to be the same depending on what method one is taken. Same thing with poisons. Why do you think eppi pens are shots and not pills? In terms of poisons, whatever method takes longer to process and be lethal, means a greater chance of getting help and living through it, so in that regard I would say less lethal.
Look at DMSO and see what it can do and why it's used as a delivery mechanism for things. If anyone has messed with DMSO, you get a little bit on your skin, your instantaneously "tasting" garlic. Not all chemicals are like that though. It all depends on the chemistry.
As to autism. Our knowledge (at least used to be, as "woke" language is making it's way through the AMA, I can foresee a regression) and how to prevent it with "geriatric" mothers (those that give birth, especially 1st timers, after 35 I believe is the start of that age range) also changes.
Now, there has been a government study just recently, that said that the covid vaccine has affected women's cycles (they are longer), so that tells me, even though it may be superficial) that it affects the endocrine system (as this is also controlled by hormones). Now, does that mean that we can jump to the conclusion that this causes autism. not at this point. We would have to follow those same women thru parturition to see if their children have it (if they do have children and probably up the testing size as well). Even then, there would be variables. Even though, I would probably say studying the kids that were born from vaxxed parents and if the vaxx is still a thing when they get it so young and through their entire life, how that affects fertility. As an aside, the medical person that was relaying the results of this study was using "woke" language. While that doesn't in of itself mean that the report is wrong, I start to look at the person like some would with doctors that smoke like a haystack and yet say smokes are bad for you. Science should not be involved in politics and once it is (and it has been throughout this entire time), that takes a certain amount of trust out of the equation.
I would also encourage those to read up on the history of what brought about the limit of a virus to be thought of as not airborn as that would have implications of how this particular virus was thought of as not airborne and only on surfaces. The problem is, if this little history lesson is true, I would have to wonder where else something similar has happened.
Sometimes running before we walk, can be a very bad thing. And we still don't know what the long term implications of the policies are going to be (and even if the vaccine (or whatever the item is in question) isn't a bad thing, but very good, how something is implemented can screw it all up). Oh and long term usually is within the range of 5 to 10 yrs as a good range to start applying what long term affects could b, not where we are at now by a long shot. At least that was the way that it used to be when I was learning all this stuff as it relates to equine.
Think about Xrays, something that we still use. But we have learned all the dangers associated with it. A wife of a friend of my parent's was an xray tech. This was before all that gear and protocol, died with massive amount of skin cancer.
My grandfather was a telephone lineman before all the gear. Died of cancer as well.
I'm not saying that the vaccine is evil or not a good thing to have etc, I actually have to wonder what this would mean for cancer medicine in general, but again, how things are implemented very much affects how things proceed thereafter.
