Immunization against meningococcus C has been recommended in France since 2009 (infants from 12 to 24 months of age, and catch up vaccination up to 25 years of age). It has been reimbursed since January 2010. We had for aim to assess the vaccine coverage in 2011.
Method: The study population included mothers of children targeted by the recommendation. They were recruited using Internet data (quotas based on the French National Institute of Statistics (INSEE) data based on a census made in 2007) based on the Institut des Mamans panel and its partners. The mothers had completed a standardized questionnaire and reported all vaccinations mentioned in their child's health-record.
Results: We included 3000 mothers of children, 0 to 35 months of age, (1000 for each of the following age range: 0-11 months, 12-23 months, 24-35 months), and 2250 mothers of teenagers, 14 to 16 years of age. Vaccination was deemed "essential/useful" for respectively 90.2% (CI 95%: 89.2-91.3) and 87.8% (CI 95%: 86.4-89.2) of mothers. Vaccine coverage levels were 32.3% (12-23 months), 57.3% (24-35 months), and 21.3% (14-16 years).
Comments: Two years after the Ministry of Health's decision to reimburse this vaccine, vaccine coverage levels were much lower than they should have been, to expect effectiveness of the vaccination policy. Only 21.3% of teenagers had been vaccinated, and 32.3% of infants during the second year of life.
