This is my answer now when people of authority over me are asking if I have had my vaccine yet.
I tell them I'm in the control group that is not taking it.
I tell them that If I die from COVID, it means I probably should have got the vaccine. If they die, it means they shouldn't have, and at least now there is a way to know the bottom-line effectiveness of the vaccine...
I've found this gives them pause and sounds just medical enough to confuse their tiny sheep mind. I also say it with a certain degree of certainty and relief in my voice, just to keep them thinking.
Ask them what the acceptable window is for "known side-effects." I guarantee you it's not 2, 3, 4 or 5 decades.
Where's the study indicating that the rise in cancer and other diseases aren't directly attributed to being vaccinated/over-vaccinated? How do we know these diseases later in life aren't the direct/indirect result of vaccines?
We're more vaccinated than at anytime in history and yet digenerative diseases are sky-rocketing... This is the era of modern medicine? No thanks, I'm not interested.
And yes, your points are very good as well. There's just too many variables to call vaccines "Safe." Yeah, they may be safe in the context that you're not likely to keel over dead in 24 hours, but are they safe, 20 years down the road? Nobody knows that.
