The COVID-19 pandemic has stress-tested all sectors and spheres of human activity, exposing countless weaknesses and fault lines - many of which were already known but ignored. The often-neglected health of migrants and refugees is one such area. While the world is still trying to recover and to ‘build forward better’ post-pandemic, there is both an opportunity and an imperative to address migrant and refugee health as an essential component of health systems and public health response ^[1]. Missing this opportunity will not simply perpetuate the inequities and injustices that many migrants and refugees have long experienced 
 it will also make it much more likely that efforts to strengthen global health security and pandemic pre- preparedness will continue to be inadequate, leaving the world at greater risk of severe health, economic and social impacts when the next pandemic strikes.
