Mother's own milk (MOM) is ideal for infant growth and health. When MOM is unavailable, donor human milk (DHM), rather than infant formula, is recommended for at-risk, preterm or sick neonates (NN), in view of its protective effects. Human milk banks (HMB) collect, secure, process and distribute DHM. In Switzerland, there is insufficient and unequal access to DHM in the absence of a national policy framework. With the support of the State of Vaud, the CHUV and the Interregional Blood Transfusion of the Swiss Red Cross will open the first HMB in Romandy in 2022. This HMB offers an innovative system in Switzerland, based on complementary expertise, in order to guarantee the quality and safety of DHM and to support the promotion of breastfeeding and human milk donation.
