Life-course vaccinations for migrants and refugees. Drawing lessons from the COVID-19 vaccination campaigns

Covid-19 showed once more, and very evidently, that some disadvantaged subgroups, including mi- grants and refugees (M&Rs), are at higher risk of contracting a disease or suffering from its severe con- sequences in areas with high transmission [1,2]. This may be due to their living conditions, which make physical distancing difficult, and/or to their legal status, which may exclude them from health care services. Additionally, COVID-19 reminded us that M&Rs tend to also have suboptimal vaccination coverage compared to the general population due to several concurrent factors [3,4]: – exclusion from health and vaccination plans and systems, often due to a lack of legal entitlements to health care or due to administrative/residence barriers; – health system barriers due to language, lack of cultural sensitivity, lack of outreach and community engagement capacity, lack of collaboration with civil society organisations, barriers to primary care, and vaccination services access, including vaccination costs; – high mobility of M&Rs; – lack of confidence in the health system and misconceptions about the vaccine. We propose some elements useful for orienting the research agenda and generating debate based on the experience of the COVID-19 pandemic. While M&Rs experienced exclusion due to the pandemic in many contexts, in others, it has been an opportunity not just to maximise coverage, but also to set up, test, and implement new, effective, and replicable approaches in vaccination services.
