Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Preterm neonates are fragile to infections. Their immune system is immature, yet in France, primary vaccines are injected at two months of age, as in term infants.

Recommendations for vaccinations in infants have changed in France in 2013, suppressing the second injection at three months after birth. Preterm and full-term born infants are now vaccinated at two and four months of age, but no data regarding efficacy in very preterm infants have been registered.

The investigators hypothesize that two vaccine injections (at two and four months) would be less efficient than three injections (two, three and four months) in very preterm-born infants.
