Context: I have a PhD in physics, and I've got a great grasp of ventilation and filtration. I don't know much about the immune system... My biology training never progressed much past Mitochondria are the powerhouse of the cell. I don't have qualifications in the subject, but my qualifications help me assess other experts.

Experts often get things wrong, but they tend to become less wrong over time. See the shifting consensus about aerosol spread.

Experts think vaccines are a good idea. The data continues to reinforce that position.

If you were a family member, an old friend, or otherwise closely connected to me, I'd talk to you on the phone. I love my family, and I would not sit down and consume anything with you. You literally could not pay me enough. Not because I abhor a liberal discussion--quite the opposite. You've shown yourself to be irrational and unwilling to adapt your position, and as a result you've managed to catch Covid a second time. Your wife got it too? I'm not going to waste my time and breath on you.

Consider this: what would it take for you to reconsider your position? Because billions of doses of several different vaccines have been delivered to an exceptionally weary world, and a tiny fraction of those recipients have seen negative side effects.

Vaccinations are more effective at preventing disease than recovering from the native variant: https://www.cdc.gov/mmwr/volumes/70/wr/mm7044e1.htm?s_cid=mm...
