The COVID-19 pandemic has highlighted how social vulnerability of some groups within countries increases their risk of infection from communicable diseases; hinders access to treatment and preventive measures, including vaccination; and, overall, exposes them to
worse health outcomes. Their higher exposure to communicable diseases due to social vulnerability may affect not only socially vulnerable population groups, such as migrants and refugees (M&R), but also the population at large. G20 countries should jointly commit to develop internationally coordinated domestic policies, as well as international aid programmes, ensuring an inclusive, free-of-charge and proactive COVID-19 vaccination offer to M&R, irrespective of their legal status; and to extend this approach beyond the current pandemic and the COVID-19 vaccine, in order to reduce health inequities and enhance preparedness for present and future health threats.
