Public health vaccine engagement postfrom @yalesph

[01]

Overview

This is a graphic created by the Yale School of Public Health. It features a text overlay with a humorous and engaging question, 'Ask your besties which childhood vaccine you are,' set against a minimalist, textured blue background. The purpose is to use a popular social media trend format to promote awareness and discussion around childhood vaccinations.

Steal this for your own video

Ask your [relationship group] which [unexpected identity category] you are

Hook and payoff

The promise the opener makes, and how the video pays it back

Hook

The entire single slide acts as the hook. It presents a low-friction, intriguing question that leverages social relationships ('ask your besties') to spark immediate curiosity and a desire to participate.

Payoff

The payoff is intentionally withheld from the visual slide. The entire structure is designed to compel the user to move to the caption for context and the comments section for the social payoff of seeing others' answers and sharing their own.

Narrative framework

The structural pattern this video runs on

Framework

The Social Identity Prompt

Reframe a potentially complex or dry topic as a lighthearted, shareable personality quiz. This leverages social media tropes ('ask your besties', 'which X are you?') to lower the barrier to entry and drive engagement directly into the comments section.

  1. 1

    The Identity Question

    Poses a question that assigns a personality type or identity ('which... you are') using an unexpected category (childhood vaccines). This gamifies the topic and creates a conversational starting point.

  2. 2

    The Authority Anchor

    A subtle branding element at the bottom of the slide grounds the playful prompt with institutional credibility, adding a layer of purpose and authority to the post.
