> You can never know anything for sure.
But you can? e.g. "We know that there are no side effects that are common enough to be of real concern."?
What deficiency do I have that prevents me from knowing anything for sure that you don't have?

I personally don't see any good reason to think that the risk for long term side effects from the vaccine is higher for the vaccine than for COVID itself.
You can however guess, and make good guesses (I'm planning on getting the vaccine). But it does no one any good to fail to outline unknowns that are steelmanned by "we can't possibly know".
This is a common, but confusing, use of "you" in American English.
