^aThe vaccine trust score is based on four questions (see ESM for details) and has a range from 0 to 5. The “Yes/No” questions are encoded 1 and 0 and the fourth question is encoded 0, 1, and 2. The score corresponds to the sum of each modality

^bThe vaccine hesitancy score is based on eight questions (see ESM for details) with a 5-point Likert scale from “Strongly disagree” (0 or 4) to “Strongly agree” (4 or 0). The modality “Do not know” is encoded 2 and questions 3, 4, 5, and 7 have been reversed. The score per individual corresponds to the sum of each modality
