Arguing with Jeff about the vaccines is like arguing with your Uncle about that 50lb fish he caught that one time no one saw.

You can show him sonar images of the lake showing there are no fish that big there. You can show him his line was only rated for 5lbs and would have snapped. You can show him his rod would have literally splintered apart under the strain...

And he'll still insist he caught that 50lb bass
