Invitation letter
 Consciousness raising on the severity of pertussis in infants, the HCW’s personal risk and the risk of peer HCWs to contract and transmit pertussis.
 Information on the percentage of HCWs who feel they have a professional responsibility to prevent pertussis in infants and intend to accept the pertussis vaccination.
 The persuasive communication message of the invitation letter is “protect your patient, vaccinate yourself”.
 The above messages are presented in a gain frame (Werrij et al. 2012), emphasising that by vaccinating against pertussis a HCW has done everything in his or her power to protect infants against pertussis.
 Persuasive communication stimulating to deliberately decide and asking to imagine how one would feel if they would not deliberate on the vaccination decision.
 Stimulating HCWs to pick a date and time to get vaccinated (goal setting)
 Propose that they visit the vaccination programme website to provide their own cue
for action in the form of a text message or e-mail. This is again presented in a gain frame, emphasising that by planning the vaccination they are more likely to attend the appointment and get vaccinated.
Information folder and website
Present the same information and the same methods as described for the invitation letter. Additionally, they include:
 Section on beliefs selection, where important misconceptions are corrected and
influential positive beliefs are affirmed.
 A number of peer HCWs are introduced, who show that they were uncertain about
their vaccination decision (or did not deliberate about the choice) at first. However, after reflecting on risks and personal and professional values they are happy they made a deliberate choice to accept vaccination.
 The posters show a selection of the peer HCWs.
Deliberation tool
The deliberation tool is an online, game-like platform with cards, which acts as decisional and value clarification tool, with stimulating a deliberate decision as its main goal. It is based on PlayDecide, a card-based public engagement tool (Bandelli et al. 2011, Felt et al. 2014). In the deliberation tool, various cards are shown in four stacks: cards with information, with experiences, with values, and with issues. HCWs are invited to choose from each stack at least one card they most agree with or of which they feel it supports their decision process on vaccination. Information cards are used to present the consciousness raising information as also described in the above-described content. Experience cards present scenario-based risk information and introduce anticipated regret. Value cards invite reflections on personal and professional values through presenting peer models, and issue cards trigger common questions HCWs might have. If they have chosen at least one card from each stack, they are asked to join an online discussion with other HCWs who also completed the tool. This provides an opportunity for social comparison.
