Data used throughout the study
| Responses | Baseline for univariate Bayesian regressions | |
|---|---|---|
| Vaccine confidence* | ||
| “I think vaccines are safe” | Likert scale recoded to “strongly disagree”, “strongly agree”, and “neither strongly agree nor strongly disagree” | Not strongly agree |
| “I think vaccines are important for children to have” | As above | As above |
| “I think vaccines are effective” | As above | As above |
| Vaccine uptake† | ||
| If respondent has children: “…have any of your children ever received a vaccine that was supposed to prevent them from getting childhood diseases…?” | Yes, no, do not know; “do not know” responses are recoded to “no” | No |

| “[How much] do you trust medical and health advice from medical workers, such as doctors and nurses…?” | A lot, some, not much, not at all; responses are recoded to “high” (a lot) and “low” (others) | Low |
| “How much do you trust…traditional healers…?” | A lot, some, not much, not at all; responses are recoded to “high” (a lot) and “low” (others) | Low |
| Information seeking | ||
| “Have you…tried to get any information about medicine, disease, or health in the past 30 days?” and “Would you…like to know more about medicine, disease, or health?” | A joint information-seeking behaviour variable is defined with responses “high” (if “yes” answered to both statements) and “low” (otherwise) | Low |
| Demographics and socioeconomic status | ||
| Sex | Male or female | Female |
| Age | Integer-valued age, scaled to have a mean of 0 and unit SD | No baseline |
| Income quintile | Quintiles: Q1 (lowest income) to Q5 (highest income) | Q1 |
| Religion: “Could you tell me what your religion is?” | For each country, religion is recoded into the most frequently reported religion in a given country (largest), all other religious affiliations (minority), or refusal to answer (refused) | Other |
| Education | Years in education grouped into <9 years, 9–15 years, and ≥16 years | <9 years |
| Science education: “Have you…learned about science at [school]?” | Primary, secondary, university, no, do not know; “primary” and “do not know” responses are recoded to “low”, with all others to “high” | Low |
*
As data on perceptions about the religious compatibility of vaccines was not posed to respondents in the Wellcome Global Monitor, we only consider three statements on vaccine confidence.
†
For this question, vaccine-preventable diseases were given as examples to respondents, which varied by country (see appendix 1 pp 28–29).
