Write public health campaign messaging that persuades without overstating what the evidence actually says
Drafts audience-specific messaging for a public health awareness campaign, keeping every factual claim tied to what's actually cited by the requester and routing any missing statistic back for verification instead of inventing one.
The prompt
Ready to copy — highlighted parts are example details you can swap.
You are writing messaging for a public health awareness campaign aimed at a specific audience segment, for a specific action the campaign wants to encourage. CAMPAIGN TOPIC AND GOAL Encouraging seasonal flu vaccination among adults who haven't gotten one in the past two years. TARGET AUDIENCE SEGMENT Working adults aged 30-50 without a regular primary care provider, mostly reached through workplace channels. FACTS OR STATISTICS PROVIDED TO CITE Local health department confirmed free flu shot clinics are available at three community sites through the end of November, no appointment needed. CHANNELS THIS WILL RUN ON Workplace break-room posters and a short internal email blast. BARRIERS THIS AUDIENCE FACES TO TAKING THE ACTION Lack of a regular doctor makes it feel like a hassle to figure out where to go; many assume it costs money or requires an appointment. RULES Write messaging that addresses the specific barriers this audience actually faces (cost, access, distrust, inconvenience, competing priorities) rather than generic "here's why you should" messaging that assumes the only obstacle is awareness — if a barrier is access-related, the message should point toward removing that barrier (where to go, what it costs, whether it's free), not just repeat the recommendation more emphatically. Use only the facts or statistics explicitly provided to you, cited exactly as given — if a claim would strengthen the message but no supporting fact was provided, write a placeholder noting "insert verified statistic here" rather than inventing a plausible-sounding number, since a fabricated statistic in public health messaging is a credibility risk that can undermine the entire campaign if ever traced back. Match tone and format to the audience segment and channel, but do not use fear-based messaging that overstates risk beyond what the provided facts support — persuasive does not mean alarmist, and overstating risk to drive action tends to backfire into distrust once audiences sense the exaggeration. Write at least two variants where the campaign goal could reasonably be communicated with different framings (a benefit-forward frame and a barrier-removal frame) so the requester has a real choice, not a single take dressed up as the only option. WHAT NOT TO DO Do not name a specific health authority, study, or guideline as the source of a claim unless that source was given to you explicitly — attributing a claim to an unverified source is worse than leaving it unattributed. MANDATORY DISCLAIMER Add a note to the requester stating that every factual claim in this messaging must be verified against current public health guidance by a qualified public health official or clinician before publication, and that any placeholder statistic must be filled with a verified source before this campaign runs. OUTPUT FORMAT 1. The internal disclaimer note. 2. Two messaging variants (benefit-forward, barrier-removal), each with headline and body copy sized for the stated channel. 3. A list of any placeholder statistics that still need a verified source.

Why this works
Public health messaging that only restates "you should do this" fails the audience that already knows the recommendation but faces a practical barrier to acting on it — addressing the specific named barrier (no regular provider, assumed cost or appointment hassle) rather than generic persuasion is what actually moves behavior, because the messaging now removes the exact obstacle in the audience's way instead of repeating information they've likely already heard. The instruction to use only explicitly provided facts and to insert a placeholder rather than inventing a statistic addresses a specific and serious risk in public health content: a fabricated number that later gets fact-checked and found wrong doesn't just discredit that one claim, it gives skeptical audiences a concrete reason to distrust the entire campaign, which is a much larger cost than a temporary placeholder. Capping the intensity of the messaging to what the provided facts actually support, rather than allowing fear-based escalation, reflects a well-established pattern in health communication research: messaging that overstates risk to drive urgency tends to produce short-term compliance at the cost of longer-term credibility once the audience recognizes the exaggeration, which is a worse outcome for a campaign that will need to be trusted again in future cycles. Requiring two distinct framings (benefit-forward versus barrier-removal) rather than a single take gives the requester an actual choice grounded in which barrier matters more for this specific audience, instead of presenting one draft as though it were the only reasonable option. The disclaimer requiring verification of every factual claim before publication exists because campaign messaging is public-facing content representing an organization's authority on health guidance, and that authority is only as good as the accuracy of what it claims — a step no drafting tool can substitute for.
What you get back
Barrier-removal variant — headline: "No doctor? No appointment needed." Body: "Get your flu shot at one of three community clinics through the end of November — free, walk-in, no appointment required." Placeholder flagged: none used, all claims traced to the provided fact about free walk-in clinics.
