Health information behaviour and health literacy on COVID-19 vaccination of the general population in Germany—findings from the CoSiD study

Abstract

Background: Although COVID-19 vaccination reduces severe disease progression as well as hospitalisations and deaths, every fourth to fifth person in Germany is not vaccinated against COVID-19. Effective information and communication measures are needed to reach these people. For this, it is important to know the information behaviour as well as the health competences in the area of COVID-19 vaccination, especially of previously unvaccinated people. Methods: The third representative population survey (November/December 2021; n = 4366) of the CoSiD study (Corona vaccination in Germany) was conducted as a combined telephone and online survey. Bivariate correlations between reported information behaviour, subjective health literacy and vaccination status and intention are investigated. In addition, multivariate correlations of socio-demographic characteristics and subjective health literacy are analysed. Results: Undecided people and people that are more likely to vaccinate were overall less likely to report a good subjective level of information (46.1%; 41.1%) and competences in evaluating information about COVID-19 vaccination (36.5%; 38.8%) as well as decision making (39.0%; 35.9%). Unvaccinated people without vaccination intentions are more likely to report observing information rated as untrustworthy or wrong (60.3%). People with a lower level of education, younger people and people with a migration background report lower levels of heath literacy. Discussion: Communication measures to promote health literacy should specifically address people with uncertain vaccination intentions as well as younger people, people with lower levels of education and people with a migration background.
