Introduction
Pertussis is a dangerous disease for young infants. They suffer the greatest risk of severe complications and are too young to be fully protected by vaccination(Greenberg et al. 2005, Winter et al. 2012, Heininger et al. 2014). Despite longstanding vaccination programmes with high coverage, several countries have reported a resurgence of pertussis in the last few decades(Celentano et al. 2005, McIntyre et al. 2009, de Greeff et al. 2010, Amirthalingam 2013, Burns et al. 2014, Miller 2014). This places infants at risk of pertussis infection(McIntyre et al. 2009, van der Maas et al. 2013).
To reduce the burden of pertussis for infants, some countries introduced more targeted vaccination approaches to their childhood vaccination programmes. One of these approaches is cocooning(de Greeff et al. 2010, Chiappini et al. 2013, Burns et al. 2014, Van der Maas 2014). In a pertussis cocooning strategy, a pertussis-containing vaccine, most often the combined tetanus toxoid, reduced diphtheria toxoid, and acellular pertussis (TDaP) is offered to those around a newborn. The aim is to prevent transmission to the baby. The target groups for cocooning vaccination include parents, close household contacts, and healthcare workers who take care of infants.
Given the international debate regarding the uptake of pertussis cocooning among intended recipients as well as on policy level, the expected acceptance of this strategy should be considered before implementation(Forsyth et al. 2007, Leboucher et al. 2012, Urwyler et al. 2014, Williams 2014). A well-planned implementation strategy is crucial to prevent an uptake problem and to ensure widespread acceptance. This strategy should be carefully linked to the relevant determinants of acceptance(Grimshaw et al. 2004, Grol 2013).
Multiple studies describe the determinants of accepting pertussis vaccination for cocooning, investigating both the intention to accept and the actual acceptance in diverse target groups (Goins et al. 2007, Wicker et al. 2008, Cheng et al. 2010, Top et al. 2010, Miller et al. 2011, Baron-Epel et al. 2012, Beel et al. 2013, Donnan et al. 2013, Wiley et al. 2013, Bodeker et al. 2014, Lu et al. 2014, Rossmann Beel et al. 2014, Suryadevara et al. 2014, Vasilevska et al. 2014, Clarke et al. 2015, Dempsey et al. 2015, Hayles et al. 2015, MacDougall et al. 2015, O'Leary et al. 2015, Tuckerman et al. 2015, Wong et al. 2015, Hayles et al. 2016). Wiley et al., for example, report that a healthcare provider’s recommendation, the belief that the vaccine is safe and effective, and the access to good information about pertussis correlate with pregnant women’s acceptance of postpartum pertussis vaccination in Australia(2013). Other studies involving paediatric healthcare professionals as well as parents also find that the perceived risk of pertussis, previous vaccination acceptance, and knowledge influence acceptance (Goins et al. 2007, Wicker et al. 2008, Cheng et al. 2010, Top et al. 2010, Miller et al. 2011, Baron-Epel et al. 2012, Beel et al. 2013, Donnan et al. 2013, Bodeker et al. 2014, Lu et al. 2014, Rossmann Beel et al. 2014, Suryadevara et al. 2014, Vasilevska et al. 2014, Clarke et al. 2015, Dempsey et al. 2015, Hayles et al. 2015, MacDougall et al. 2015, O'Leary et al. 2015, Tuckerman et al. 2015, Wong et al. 2015, Hayles
