Elaborate. And please don't get into the immocompromised who doctors would advise not to take the shot.
Some healthy young men that have recovered from covid have weighed the benefits of the supposed extra protection that comes from vaccination vs their own healthy natural immunity.
They looked at the data, and felt that it's not conclusive long-term evidence. They have gone through a multitude of other health issues in their life and have determined that for them, their body is great at protecting itself and they don't require the protection given by the vaccines.
I didn't spend my life in their body so I can't say whether or not they are correct or not, I can only accept that after looking into the matter at length, they chose what they feel is best for their body. They may be scientists or doctors themselves. They may be specialists in the field.
But I can guarantee you that educated people that are informed on the matter have chosen not to get vaccinated. I know some. And just because you dismiss their opinion on the matter, or everyone here as a group dismisses their opinion on the matter, doesn't mean they're misinformed.
