Acceptance of a post-partum influenza vaccination (cocooning) strategy for neonates in Greece

Young infants are at increased risk for influenza-associated serious illness, onset of complications, utilization of health-care services, and hospitalization. We investigated the feasibility and acceptance of an influenza vaccination (cocooning) strategy by household contacts implemented in a maternity hospital and the neonatal unit of a pediatric hospital in Athens. A total of 224 mothers (mean age: 30.2 years) who gave birth to 242 neonates were studied. Of them, 165 (73.7%) mothers were vaccinated. Multiple logistic regression revealed that statistically significant factors associated with increased vaccination rates among mothers were: being of Roma origin (p-value = 0.002), being an immigrant (p-value = 0.025), giving birth to a neonate with birth weight
