|Item 3. What (materials): Describe any physical or informational materials used in the intervention, including those provided to participants or used in intervention delivery or in training of intervention providers. Provide information on where the materials can be accessed (for example, online appendix, URL)||
Describe the content of any informational material provided to the healthcare worker:|
Does it include unbiased, evidence-based and up-to-date information about the vaccine’s effectiveness and side-effects?
Does it include unbiased, evidence-based and up-to-date information about the severity of the disease in question and its prevalence in your setting?
Does it cover the questions, fears and concerns that older adults commonly have in your setting?
|Item 4. What (procedures): Describe each of the procedures, activities and/or processes used in the intervention, including any enabling or support activities||(No elaboration made)b|
|Item 5. Who provided: For each category of intervention provider (for example, psychologist, nursing assistant), describe their expertise, background and any specific training given||

Where possible and if they are also a vaccine target group, describe the proportion of healthcare workers who had received the vaccine themselves
Describe the content of any training given to the healthcare worker:
Did it discuss their responsibility for vaccination communication in relation to other healthcare workers or other parts of the health services? Had relevant stakeholders, such as professional bodies, been involved in the content and delivery of the training?
Did it emphasize the value of providing unbiased, evidence-based information about the disease and the vaccine?
Did it include a clarification of the aim of the communication; and a discussion of their role and the role of the older adults in vaccination communication and decision-making?
Did it reinforce the message that healthcare workers should avoid introducing their own criteria for determining who should and should not receive vaccines?
|Item 6. How: Describe the modes of delivery (such as face to face or by some other mechanism, such as internet or telephone) of the intervention and whether it was provided individually or in a group||
Describe how the intervention was integrated into the healthcare worker’s routine practice, including:|
Whether the healthcare worker was expected to raise the issue of vaccination or whether this was usually left to the older adult
Whether the healthcare worker had sufficient time to deliver the intervention and how this was determined
Describe how healthcare workers accessed relevant patient data, including information about the person’s vaccine history or underlying health conditions
|Item 7. Where: Describe the type(s) of location(s) where the intervention occurred, including any necessary infrastructure or relevant features||Describe the extent to which the intervention was delivered to older adults opportunistically (for instance, when attending appointments about other healthcare issues) or at designated time points or events (for instance, during vaccination days)|
|Item 8. When and how much: Describe the number of times the intervention was delivered and over what period of time including the number of sessions, their schedule and their duration, intensity or dose||(No elaboration made)b|
|Item 9. Tailoring: If the intervention was planned to be personalized, titrated or adapted, then describe what, why, when and how||
