SHARE Migrants are in danger of becoming an afterthought in the international effort to vaccinate against Covid, with UN agencies fearing many will be too scared of authorities to accept a shot. There are also concerns around compiling data on refugees and migrants, many of whom are reluctant to engage with officials due to a lack of trust, the agencies said. Dr Jaime Calderon, the senior migration health adviser at the International Organisation for Migration’s regional office in Vienna, says governments must take steps to ensure refugees and migrants are not left behind, and go beyond simply procuring adequate vaccine doses.
