Although public and private institutions have spent billions of dollars on COVID-19 vaccination campaigns, many of which claim to be "equity-focused," few articles to date have objectively described the landscape of these campaigns or identified existing gaps with a focus on those populations disproportionately impacted by the virus. To these ends, a high-level landscape analysis of COVID-related communication campaigns was conducted. Analysis of 15 COVID-related communication campaigns based on six criteria (i.e., understandability, accessibility, actionability, credibility/trustworthiness, relevance/relatability, and timeliness) identified successful efforts, including campaigns aligned with the World Health Organization's Strategic Communications Framework and rooted in community co-design and communication science. The analysis also revealed five common shortcomings: campaigns were not end-user focused, only "checked the box" when communicating with historically under-resourced communities, were largely broadcast-focused and rarely involved two-way engagement strategies or tactics, demonstrated poor use of online communication approaches and failed to moderate campaign comment boards/social media sites, and commonly targeted "intermediary" audiences with materials that were not "end user ready." Based on these findings, the authors offer recommendations to guide funding and development of future health communication campaigns focused on reaching diverse audiences.
