Anyone read the series called The Last Survivors by Bobby Adair and T.W. Piperbrook? There is a sequel series by Piperbrook called The Ruins.
This is a post-apocalypse set in which an RNA-altering “vaccine” turned many people into zombie-like creatures and destroyed the world’s civilizations.
When we were told that COVID’s “vaccine” was RNA-altering, all I could think about were these book sets.
Oh, BTW, the issue being “cured” was... wait for it... toenail fungus.
Interesting!
