[Vital impetus… the blood].

In 2022, 2 years on from the start of the pandemic, the Instituto Mexicano del Seguro Social (IMSS, Mexican Institute for Social Security) has been reorganizing its services at full, out of which blood banks play a key role. In addition, on June 14 it is celebrated the World Blood Donor Day by the World Health Organization and this year Mexico was the host country for the celebration. Therefore, it is important to highlight the work carried out in blood banks, ranging from their main activity, which is the recruitment of blood donors and the blood components production, to the different interventions they have in the field of transplantation, diseases emerging diagnosis and the development of new therapeutic modalities, such as, for example, cell therapy.
