Moderna's Influencer Strategy: Redefining Healthcare Marketing Success
Influencer MarketingCoegi built a 150 creator partner community for Moderna's Spikevax vaccine, work the agency reports helped drive nearly 24% of all US vaccine conversions.
Case in 60 seconds
By 2023 COVID fatigue had left many people resistant to pandemic messaging while a well funded rival competed in the same space, so Moderna needed to promote Spikevax and raise vaccination rates among high-risk individuals.
The campaign appears to turn on trust sitting with communities rather than institutions, because audiences weary of pandemic talk would hear a vaccine message from a member of their community sooner than from a brand.
Coegi positioned Spikevax as a routine choice in preventive healthcare carried by community members rather than by promotional messaging, casting creators who belonged to the communities the brand wanted to reach.
Coegi and the client identified 150 creators, each representing one of the persona communities defined for the brand, and those collaborations established the #SpikevaxPartner Community of nano and micro-influencers. The strongest content was amplified on paid media channels to extend the Spikevax messaging, while Attention Unit Scoring, script lift analysis and audience emotional response analysis supported real-time optimization.
Coegi reports the community helped drive nearly 24% of all US vaccine conversions and over 503 million impressions across organic and paid channels that surpassed the attention score benchmark by 9%. The agency also reports engagement rate goals surpassed by 484%, nearly 72,000 Spikevax page visits and market share increasing 23% YoY, which the page presents as the business impact of the work.

Why Coegi's strategy worked
- 1
Casting creators for membership of a community rather than for follower scale gives a regulated brand a messenger its audience already trusts, which appears to be how 150 nano and micro-influencers carried a vaccine message through message fatigue.
- 2
Framing a product as a routine preventive choice rather than as a response to a crisis suggests a way through fatigue, because routine positioning asks the audience for a habit rather than for renewed attention to a tired subject.
- 3
Measuring attention lift and emotional response alongside platform counts reads as a check on whether creator content was absorbed, which matters more where the objective is a behaviour such as vaccination than where it is reach.
- 4
Amplifying the strongest creator content on paid media extends a message without recasting it, so the credibility built by a community messenger travels into bought placement rather than being replaced there by brand voice.
