Before the COVID-19 pandemic, migrants, refugees, and asylum seekers were considered some of the most socially vulnerable groups among other sub-population groups. There is a ponderance of evidence indicating that during the COVID-19 era: (1) their social vulnerabilities were underpinned by not-so-new but re-emerging and adapting pre-existing social drivers such as xenophobic stigmas and nationalism; (2) weaponizing measures used to fight the pandemic such as social distancing to alienate these groups socially—social exclusion; and (3) their social vulnerabilities were exacerbated during the COVID-19 pandemic directly through the impact of the viral infections (loss of loved ones and social support) and indirectly through their audacious exclusion during the execution of different measures to buffer the socioeconomic impact of the pandemic. Using data from a recent qualitative study, we illustrate how the absence or ineffectiveness of social welfare systems failed these vulnerable groups during the COVID-19 pandemic, negatively impacting all aspects of their lives.
