Your governor is a republican....
No one knows who has caught covid previously or been vaccinated, and yes, you are super duper protected from dying from covid. You want a tattoo or papers required to show your status?
But breakthrough cases of covid, still occur in those who have previously been infected.... It's a hit or miss, though likely a miss.... There is no guarantee that you're not infected and spreading it free as a bird, to others.
The mask alone, does not prevent an infected person from spreading infection to others, it just reduces the spread of infection if everyone is wearing one.... A reduction in spread is better than no reduction in spread.
