Abstract

The French 2013 immunization schedule having a goal of simplification with comparable efficacy, has decreased the number of injections and removed the injection performed at three months of age in the general population. Apart from the prevention of invasive pneumococcal infections for which it is recommended to maintain three dose primary immunization, vaccination of premature is not addressed in this new calendar. Can the extremely preterm infants (<33 weeks of gestational age) benefit from this new schedule or should we keep them in three injections schedule? The objective of this paper is to clarify this point through the data available in the literature. Children born prematurely and especially the "extremely premature" born before 33 weeks are at high risk of infections, some of them are preventable by immunization. Although there is no clinical evidence, for pertussis, pneumococcus, Haemophilus influenzae b, hepatitis B, whatever the immunogenicity criteria, immunogenicity is significantly lower in preterm than in term newborn after 3 doses primary schedule. This lower immunogenicity raises concerns about the transition to two doses, about the ability to give short term protection and booster responses. Given these data, GPIP takes the position for maintaining a primary 3-dose vaccination at 2.3 and 4 months for premature infants less than 33 weeks.
