Case Study

Mobilizing a Statewide COVID-19 Response Across All 58 Counties

When COVID-19 threatened the health and safety of Californians, state leaders launched Vaccinate All 58, a massive public health initiative designed to reach every corner of California with accurate, culturally relevant information about vaccination and harm reduction.

In partnership with the California Department of Public Health, Governor Newsom’s Office, and the Center at Sierra Health Foundation, Mediasol helped lead the charge on a campaign that spanned all 58 counties.

The campaign focused on reaching communities most impacted by the pandemic, particularly low-income and ethnically diverse populations. Mediasol oversaw strategic planning, creative production, media buying, outreach, and PR efforts, developing content in 27 languages, and adapting messaging for faith-based groups, indigenous communities, and trusted local networks.
