Wait. You thought "COVID" was the name of the virus? No. It stands for "Certificate of Vaccination ID," which you'll need to show in order to attend large gatherings, board public transportation, etc, once the vaccine is available.
When I was a teen, about 35 years ago or so, I attended a movie screening at my friend's church. The movie predicted a future when we would all be required to get a tattoo, which we would have to show in order to shop or travel, and that this tattoo would be the Mark of the Beast, 666. What a crazy film, huh?
Heh yeah, I read the book.
