Recomendaciones de uso de palivizumab para la prevención de la infección por virus respiratorio sincitial en prematuros de 321 a 350 semanas de gestación

Late preterm infants (321 to 350 weeks gestation) aged less than 6 months at start of RSV station or discharged during this time may benefit from RSV monoclonal antibodies (palivizumab) administration to decrease the rates of RSV hospitalization. The Spanish Society of Neonatology considers, based on FLIP2 results in Spain, that palivizumab prophylaxis is strongly recommended if the “2 major risk factors” are present (chronological age less than 10 weeks at start of RSV season or being born during its first 10 weeks; sibling of school age or attending day-care assistance). Palivizumab is also recommended when “1 major risk factor and the 2 minor risk factors” are present. Minor risk factors are: mother smoking during pregnancy and being a male.
