I don't think any one characterization of people who got vaxed is accurate. I know one coworker who absolutely is a hypochondriac. But, I know others who seem to wear their vax status like a badge of honor. And still others who wear it like a badge of loyalty. My wife's manager got vaxed purely as a matter of convenience because he had a trip planned to Tahiti and he couldn't travel internationally without it. I know someone else who got vaxed when his brother with comorbitities caught covid and died, so he was scared into it.
