The challenge

Our client wanted to encourage consumers to get vaccinated for COVID-19 with an unbranded campaign, one focused on the public health message rather than a product. There was no playbook to follow, because the campaign would be first to market.

Health messaging at that moment had to be clear, trustworthy, and carefully reviewed. The campaign needed a strong identity, a website people could navigate easily, and a launch plan that could hold up under legal and regulatory scrutiny.

What we did

Trellist took the campaign from discovery to launch, then stayed on to support it in market.

  • Discovery grounded in the business. We led a comprehensive discovery process that included leadership interviews and industry benchmarking.
  • Brand and identity concepts. Trellist created several campaign concepts covering website UX, promotional assets, and targeted messaging.
  • A website built from the structure up. We delivered full information architecture and creative design for the new campaign site.
  • Compliance and launch, managed. Trellist led the legal and regulatory processes and built a multichannel go-to-market strategy, with ongoing support and campaign budget management.
