- Step 2: Write the core message hierarchy — primary message (one sentence) and 3 supporting messages.
- Step 3: Write channel-specific content for 3 channels: social media post (3 variations), community-facing poster headline and key points, and a health worker talking points guide.
- Step 4: Write a message for hard-to-reach or vaccine-hesitant segments specifically.

# Goal
Produce the exact deliverable requested for this use-case. Make the output practical, specific, and ready to use.

# Constraints
- Use the user's variables exactly where relevant.
- Avoid generic filler and vague advice.
- Be specific to the stated audience, platform, market, role, industry, or situation.
- Ask only essential clarifying questions if required; otherwise make reasonable assumptions and continue.

# Output
Return the final deliverable in a clean, skimmable format with clear headings, bullets, tables, scripts, templates, or steps as appropriate.
