Hospital initiation of a vaccinal schedule improves the long-term vaccinal coverage of ex-preterm children.

Preterm infants are experiencing delays in receiving routine schedule vaccines. We evaluated up-to-date immunisation status of 602 preterm infants at 5 and 24 months for DTCoqPolioHib and pneumococcal conjugate vaccine (defined by 3 and 4 doses, respectively). At 5 months, 39% (CI 95% [35-43]) of children were up-to-date for DTCoqPolioHib and 22% (CI 95% [19-26]) for pneumococcal conjugate, while at 24 months 67% (CI 95% [64-71]) were up-to-date for DTCoqPolioHib and 36% (CI 95% [32-40]) for pneumococcal conjugate. After adjustment for gestational age, a primary vaccine before discharge remained linked with a better vaccinal coverage (p<.005, OR=5.0; CI 95% [2.9-8.5]). Copyright Â
