The information needs of people with lower health literacy or from culturally and linguistically diverse backgrounds have received limited attention during the coronavirus disease 2019 (COVID-19) pandemic. In one study, the complexity of most government-produced COVID-19 information in Australia and overseas exceeded the recommended grade 8 reading level, making it too difficult for general audiences, let alone people with lower health literacy.1 We therefore compared the complexity (readability, understandability, actionability) of Australian and overseas COVID-19 vaccination information with that of other COVID-19-related information (physical distancing, mask wearing), including “easy read” resources developed in Australia and New Zealand. During March and April 2021, we selected public sources of information on vaccination, physical distancing, and face masks on government websites in Australia, New Zealand, and the United Kingdom, and by three overseas public health agencies: the Centers for Disease Control and Prevention, the European Centre for Disease Prevention and Control, and the World Health Organization (WHO). We also searched each site for resources labelled “easy read”. Readability was assessed with the Simple Measure of Gobbledygook (SMOG) index,2 which estimates the grade reading level (range, grade 5‒18); grade 8 is recommended for general audiences.3 We also used the widely employed Patient Education Materials Assessment Tool (PEMAT)4 to assess “understandability” (elements include word choice, use of visual aids, layout, and organisation) and “actionability” (the clarity of the recommended actions or steps). Two researchers independently scored each of the 24 PEMAT items (0 = disagree, 1 = agree, NA = not applicable), with disagreements resolved by discussion; the total score is the proportion of “Agree” responses, and a score of 70% is deemed “adequate”.4 We report PEMAT scores for “standard” content on a website by topic, as the linked pages were designed to be used together; we assessed the easy read items individually, as they are designed as standalone resources (further details: online Supporting Information). The statistical significance of differences between medians for information topics (vaccination, physical distancing, mask wearing) was assessed separately for “standard” and “easy read” content in Kruskal–Wallis tests; P 0.70). Twelve months into the pandemic, a considerable amount of COVID-19 public health information in Australia and overseas rates poorly on measures of readability and actionability, particularly information about vaccination. “Easy read” content (with better readability and understandability) showed that it is possible to convey information about COVID-19 in plain language, but such items were few in number and difficult to locate on websites. Our study was limited by our exclusion of multimedia formats, and our findings reflect information available in April 2021. Public health information should be easily accessible to the general public. Despite the WHO5 and the National Academy of Medicine6 endorsing plain language, practice has not been aligned with guidelines. The high health literacy demands of vaccination information in Australia has important implications for vaccination uptake.7, 8 Successfully managing the COVID-19 pandemic requires a whole-of-community response based on effective public communication and a commitment to health literacy.
