Public health warning

The pattern

This still is filed under Public health warning.

Define

A warning designed to change a health behavior (stop, screen, stay home), not to sell a brand.

Mechanism

Fear with a next step. The threat is specific. The action is doable today. Fear without an action is cruelty.

Verdict

The risk is real and the action is clear. Official or civic voices help.

Why it works

It makes an invisible, abstract threat (disease) into a visible, physical attack (lightning), and similarly makes the preventative measure (a vaccine) into a tangible defense (a shield). This makes the value proposition instantly understandable.

The big idea

A lightning bolt aimed at a small child breaks against a shield marked TOXOID, so an invisible vaccine looks like physical armour.

The offer

Protect your child with Toxoid, the diphtheria vaccine promoted by the Chicago Department of Health.

The proof

A flat claim, TOXOID PREVENTS DIPHTHERIA, signed by the Chicago Department of Health.

Lines from the ad

DIPHTHERIA STRIKES UNPROTECTED CHILDREN

PROTECT YOUR CHILD WITH TOXOID

TOXOID PREVENTS DIPHTHERIA

Steal this when

You need to sell a preventative or invisible product by visualizing what it protects against and how it acts as a barrier.

The emotion

Written to Fear. It makes the Say move.

A lightning bolt aimed at a small child breaks on a shield marked TOXOID, and the lines give the parent one clear act: 'Protect your child with Toxoid', signed by the Chicago Department of Health.
