Background: During a pertussis epidemic in 2009, the Department of Health, Victoria, Australia, implemented a cocoon program offering parents of new babies a funded-dose of pertussis-containing vaccine.We assessed vaccine effectiveness (VE) of the program in reducing pertussis infection in infants.Methods: Using a matched case-control design, infants aged Results: The study recruited 215 cases and 240 controls (response rates 67% and 25% of eligible participants,respectively). Vaccination of both parents after delivery of the infant and 28 days prior to illness onset reduced pertussis infection by 77% (Vaccine Effectiveness [VE] = 77% (confidence interval [95% CI],18-93%). After adjusting for maternal education, presence of a sibling within the household, and the infants' primary course vaccination status, the adjusted VE was 64% (95% CI, -58-92%).Conclusions: Although not reaching statistical significance, our results demonstrated that cocoon immunisation - where both parents are vaccinated in the post-partum period – may offer some protection again infant pertussis infection. Cocoon immunisation could be considered in circumstances where antenatal vaccination of the mother has not occurred.
