Since 2004, in France, pertussis booster is recommended in parents of young infants and adults likely to become parents. This recommendation adds to others such as rubella vaccination in unvaccinated or seronegative women and decennial dT-IPV booster. The objective of this study is to evaluate the impact of these recommendations in parents of young infants. Pediatricians had to include parents of infants at the first well-baby visit after birth. Vaccination data were secondary recorded from parent's health record or called upon their memory. Between June and October 2006, 41 pediatricians included parents of 400 infants (median age: 36 days). dT-IPV booster was recorded or recalled in 37.4% within the 10 previous years and 17.7% within the 3 previous years. Among this last group, only 11.8% had received a combination including pertussis. Rubella serology was declared as positive by 94% of the mothers, but the physicians obtained the information of a previous rubella vaccination in only 71.7% of the mothers. Among the 9 seronegative mothers during pregnancy, only 3 were vaccinated in postpartum. Adults' immunization guidelines are not well known and poorly applied in France. The unavailability of monovalent pertussis vaccine reduces the eligible population. Two years after the launch of the pertussis cocoon strategy, the coverage of eligible young parents remains low and many opportunities are too frequently missed on the opportunity of decenial dTPolio booster. Rubella catch up strategy should be improved. Adults' vaccination strategies and guidelines need to be better broadcasted to health care professionals and also families.
