[Is the simplification of the immunization schedule applied? Review 2 years after its implementation].

Unlabelled: Repeating evaluations of vaccine coverage (VC) is essential to measure the implementation and effectiveness of vaccination policy. We report the results of VC in infants from the Vaccinoscopie study in 2014 to assess the changes secondary to the new 2013 immunization schedule.

Method: Study conducted on Internet among a representative sample of mothers reporting their child's vaccination record.

Results: The removal of the dose of DTPa-Hib at the age of 3 months was quickly adopted since only 1 % of children aged 6 months had received three doses of DTPa in 2014 compared to 96 % in 2012. The booster dose is administered earlier for the DTPa and hepatitis B components. The shift of MMR vaccination from 9 months of age for children participating in community structures to 12 months for all children was closely followed since only 2 % of 9- to 11-month-old children received a MMR vaccine in 2014 compared to 33 % in 2012. The second dose of MMR recommended at 16-18 months of age rather than between 13 and 24 months was actually followed by an earlier administration of this dose. At 18-20 months of age, 60 % received two doses of MMR in 2014 versus 41 % in 2012. Finally, for meningitis C vaccination, a significant increase of VC was observed in children 15-23 months of age (66 % in 2014 versus 44 % in 2012).

Conclusion: The simplification of the infant immunization schedule was quickly applied and received excellent support from healthcare professionals. However, this measure alone is still not sufficient to meet the CV objectives defined by the HCSP.
