Background:
The compliance with recommendations for Pertussis vaccination was assessed in the Lyon population through vaccination coverage (VC).
Methods:
A cross-sectional study was conducted in collaboration with 10 private biological analysis laboratories between October 2010 and March 2012, on 1930 adults (>19 years of age) from the Lyon area. Proof of vaccination (PV) was requested to prove the current vaccination status.
Results:
A percentage of 30.3% (585/1930) of surveyed individuals provided a PV. A positive vaccination status was confirmed in 10.76% [CI 95% 8.45-13.48] (63/585) and didn't vary in relation to gender (P=0.57), age (P=0.06), or level of schooling (P=0.41). Coverage vaccination was not updated in parents with childbearing project (84.2% (64/76) [CI 95% 74.7-91.2]) or people in contact with children less than 6 years of age (83.6% (87/104) [CI 95% 75.6-89.8]). Pertussis vaccination wasn't confirmed in 80.0% (124/155) of those who thought being vaccine up to date.
Conclusions:
The Lyon population poorly complied with the cocooning strategy implemented in 2004. The pertussis vaccine coverage confirmed by a PV proved the inadequate rate of vaccination compared to objectives. It is mandatory to strengthen the vaccinal policy for this vaccine booster.
