The average person can expect to be in three to four car accidents during their lifetime. I'm still driving around (vaxxed, not belligerent, happy to mask for the time being).
Anyone who somehow interpreted that as "completely immune" has bad reading comprehension.
This sounds like a strawman argument that you're making, I don't know where you're getting that there's a misconception of the vaccine equating to 100% immunity. No one said that.
That's purely a psychology question, and I honestly don't know what the answer is. But it's worth noting that it's pretty much all about strawmen, and which strawmen the anti-vax crowd can be manipulated into believing.
