What’s on the Immunisation poster
A 5-row table: Disease · R₀ · Threshold.
Herd immunity threshold rises with R₀.
- Measles — 12–18 — ~92–95%
- Pertussis — 12–17 — ~92–94%
- Diphtheria — 6–7 — ~85%
- Polio — 5–7 — ~80–86%
- Influenza — 1–2 — ~30–50%
Threshold ≈ 1 − 1/R₀. Measles is so contagious that even small drops in coverage cause outbreaks.
Questions about the Immunisation poster
- What’s on the Immunisation poster?
- A 5-row table: Disease · R₀ · Threshold. Herd immunity threshold rises with R₀. Measles — 12–18 — ~92–95%; Pertussis — 12–17 — ~92–94%; Diphtheria — 6–7 — ~85%; Polio — 5–7 — ~80–86%; Influenza — 1–2 — ~30–50%. Threshold ≈ 1 − 1/R₀. Measles is so contagious that even small drops in coverage cause outbreaks.
- Who is the Immunisation poster for?
- Immunisation belongs to the Biology section rather than to a school year, because life science is not something one grade owns. Anyone learning microbiology can pin it up — a beginner, a student mid-course, or someone revising years later.
- When should you use the Immunisation poster?
- The more contagious the disease, the higher the coverage needed for herd immunity. A wall chart earns its place by being glanceable from where the work is happening, so Immunisation belongs on the wall where that life science work actually happens, within glancing distance, rather than filed away.
- What other posters go with Immunisation?
- Antibiotic Resistance, How Antibiotics Work and Aseptic Technique sit alongside Immunisation in the Biology section. Printed together they make a wall rather than a single sheet, which is how a reference set actually gets used.Antibiotic ResistanceHow Antibiotics WorkAseptic Technique
- Is the Immunisation poster free to download and print?
- Yes. Immunisation downloads as a free PDF with no account, no email and no watermark, like everything else in the Biology section. Print as many copies as you like for a home, a classroom, a library or a tutoring group; reselling the file is the only thing the licence rules out.Read the licence
- What size does the Immunisation poster print at?
- Immunisation is a vector PDF laid out for US Letter, and prints on A4 with Fit to page — the same file, no separate download. Because every mark on it is drawn rather than photographed, it stays sharp enlarged to A3, A2 or A1 at a copy shop. Colour carries emphasis only, so a greyscale print of Immunisation loses nothing.Printing guide
