Primary	Change in self-reported responsibility perception	Self-reported responsibility perception = answer to the following item: (1) "Recommending indicated vaccines is within the scope of my professional responsibilities". This item is answered on a scale from 0% (completely disagree) to 100% (completely agree).	Day 1, Day 30, Day 60, Day 90
Primary	Change in self-reported assessment of patient recommendation acceptance	Self-reported assessment of patient recommendation acceptance = answer to the following item: (1) "If I recommend(ed) an indicated vaccine, my patient (will) accept(ed) that recommendation.". This item is answered on a scale from 0% (never) to 100% (always).	Day 1, Day 30, Day 60, Day 90

Primary	Change in self-reported utilization of AIMS	Composite score of the following items: (1) "I used/will use direct, declarative language, like: "You're due for your flu shot. We'll do that at the end of this visit"; (2) "If the patient showed/shows hesitancy about getting vaccinated, I (will) ask(ed) about their concerns, and then use(d) active listening to understand their thoughts"; (3) "If the patient showed/shows hesitancy about getting vaccinated, I (will) listen(ed) to the patient's reasoning and then summarize(d) the patient's reasoning back to them to show that I understood/understand"; (4) "If the patient still has concerns, I did/will not continue efforts to convince them."; Each item is answered on a scale from 0% (never) to 100% (always).	Day 1, Day 30, Day 60, Day 90
Primary	Change in self-reported rate of patient vaccine uptake	Answer to the following item: "Estimate what percentage of your patients is/will be fully vaccinated against […]" This item is answered on a scale from 0% to 100%.; The question is being asked 8-10 times with the following name inserted for [...] in the above question: Flu COVID-19 Tetanus, Diphtheria, Pertussis HPV Hepatitis B Meningitis / Meningococcal Shingles Pneumococcal Other (which can be two other diseases that the respondent indicated)	Day 1, Day 30, Day 60, Day 90
