A very strict guideline reduced the number of erythrocyte transfusions in preterm infants, without threatening their clinical course.

The restrictive guideline for platelet transfusions reduced the platelet count thresholds for neonatal transfusions without increasing the rate of ventricular haemorrhage.

Background and aims: Antibody response may be lower in preterm infants. This study aimed to compare the immune response to vaccination against measles, varicella and tetanus in preterm and term infants and to analyze factors associated with antibody level.

Background and aims:Few studies have assessed cell-mediated immunity in preterm infants. This study aimed to compare cellular immune responses to vaccination against measles, varicella-zoster and tetanus in preterm and term infants.
