Design strategy to build trust in Merck's brand and vaccine products to combat rising irrational fear and misinformation.

I designed the template as a complete responsive specification: 375px and 414px phones, 768px and 1024px iPads, and 1280px, 1440px, and 1920px desktops. At every width, the anatomy holds: global nav, product nav, Prescribing and Patient Information links, content sections, and the persistent safety drawer. A designer or developer picking up any product knew exactly what went where before a single branded comp existed.

The pattern that carries the most weight is the pinned drawer holding Indications and Usage and Select Safety Information, each expandable in place. On desktop it rides mid-viewport; on phones it becomes stacked expandable panels. Because it behaves identically on every product site, an HCP moving from one vaccine to another already knows where the critical information lives. The consistency itself is what builds trust at a time of heightened vaccine skepticism.

With the IA locked, each product became a theming exercise rather than a design project: brand color, product logo, hero content, and audience panels drop into an anatomy that's already specified and already approved. The VAQTA example below is the template wearing a product's brand. The drawer, nav structure, and information hierarchy are untouched.
