Poor knowledge of the vaccination requirements for these patients and safety concerns often result in vaccination delay or avoidance. In order to address this issue, a panel of 11 Italian haemophilia and immunization experts conducted a Delphi consensus process to identify the main concerns regarding the safe use of vaccines in patients with haemophilia. The consensus was based on a literature search of the available evidence, which was used by the experts to design 27 consensus statements. A group of clinicians then rated these statements using the 5\u2010point Likert\u2010type scale (1\u00a0=\u00a0strongly disagree; 5\u00a0=\u00a0strongly agree). The main issues identified by the expert panel included vaccination schedule for haemophilic patients; protocol and optimal route of vaccine administration; vaccination of haemophilic patients with antibodies inhibiting coagulation factor VIII (inhibitors); and vaccination and risk of inhibitor development. This manuscript discusses these controversial areas in detail supported by the available literature evidence and provides evidence\u2010 and consensus\u2010based recommendations. Overall, participants agreed on most statements, except those addressing the potential role of vaccination in inhibitor formation. Participants agreed that patients with haemophilia should receive vaccinations according to the institutional schedule for individuals without bleeding disorders; however, vaccination of patients with haemophilia requires comprehensive planning, taking into account disease severity, type and route of vaccination, and bleeding risk. Data also suggest vaccination timing does not need to take into consideration when the patient received factor VIII replacement.<\/jats:p>","DOI":"10.1111\/hae.13756","type":"journal-article","created":{"date-parts":[[2019,4,16]],"date-time":"2019-04-16T14:55:31Z","timestamp":1555426531000},"page":"656-667","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":18,"title":["Consensus statements on vaccination in patients with haemophilia\u2014Results from the Italian haemophilia and vaccinations (HEVA) project"],"prefix":"10.1111","volume":"25","author":[{"given":"Elena","family":"Santagostino","sequence":"first","affiliation":[{"name":"Fondazione IRCCS Ca\u2019 Granda, Ospedale Maggiore Policlinico Centro Emofilia e Trombosi Angelo Bianchi Bonomi Milan Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Agostino","family":"Riva","sequence":"additional","affiliation":[{"name":"III Divisione di Malattie Infettive Ospedale L.
