Schedule English
CDC and NHS calendars are the local source of truth for timing — not a blog.
Herd immunity entered ordinary English and then got stretched. The local lens: it is a population word, not a dare to skip a shot.
No recipes, no lot numbers, no ‘which brand is best’. Licensed clinicians and official calendars own that.
Local notes
Herd as metaphor
It describes coverage in a population. It is not a personal shield you can opt into with vibes.
Side-effect talk
Official information sheets exist. This encyclopedia will not replace them.
Official pages own schedules and treatment. This atlas does not.

Mutation and variants
Populations of genomes, not cartoon villains — RNA viruses copy sloppily, and public-health names track clusters that spread.
Familiarity 92Antibiotic resistance
A shared drug budget under selection in hospitals, farms and wastewater — stewardship, not a lab manual.
Familiarity 85Biofilms
Surface cities of microbes — plaque and catheters explain persistence, without a grow-your-own kit.
Familiarity 38Hygiene and balance
Clean water saves lives; missing old microbial partners is a separate, still-debated immune story.
Familiarity 70Horizontal gene transfer
Sideways DNA traffic — conjugation, transduction, transformation as names and history, not protocols.
