| Latent Variable and Associated Items (Factor Loading Indicated a) | |||||||
| Personal Risk | |||||||
| How much of a problem is COVID-19 in America? b (−0.56) | |||||||
| Based on your own health, age and risk factors, what do you believe to be your risk level were you to get COVID-19? b (0.30) | |||||||
| Based on your overall experience with COVID-19 in both a professional and personal capacity, how serious would you say COVID-19? b (0.67) | |||||||
| Vaccine Attitudes | |||||||
| I am current on the vaccinations recommended by my primary care physician.c (0.39) | |||||||
| How important is it for you to get the flu vaccine every year? b (0.66) | |||||||
| Vaccines are important for the prevention of serious diseases.c (0.89) | |||||||
| My children are current on recommended vaccines (or, if I don’t have children, I would keep my children current on recommended vaccines).c (0.62) | |||||||
| Location of Manufacture | |||||||
| Development of a vaccine outside of the United States would reduce my likelihood of being vaccinated. c (1.18) | |||||||
| Development of a vaccine in China or Russia would reduce my likelihood of being vaccinated c (0.90) | |||||||
| Development of a vaccine in the United Kingdom would reduce my likelihood of being vaccinated c (1.30) | |||||||
| Testing Speed | |||||||
| I worry that the rushed pace of testing for the new COVID-19 vaccine will fail to detect potential side effects or dangers c (0.60) | |||||||
| I would accept a COVID-19 vaccine with full FDA approval but not one with an emergency use authorization c (0.51) | |||||||
| I would NOT accept a COVID-19 vaccine until the completion of its clinical trial and publication of results in a peer-reviewed journal such as JAMA, NEJM or the Lancet.c (0.81) | |||||||
| Likelihood of getting the COVID-19 vaccine | |||||||
| I am likely to get the COVID vaccine d (0.82) | |||||||
| Other people around me being vaccinated against COVID-19 will be helpful in controlling the pandemic c (−0.85) | |||||||
| A vaccine is important to end the COVID-19 pandemic c (−0.94) | |||||||
a All factor loadings are standardized. b These items were on a 5-point Likert scale indicating level of intensity (for specific statements, see full survey in the Supplementary Materials). c These items were on a 5-point Likert scale indicating level of agreement (for specific statements, see full survey in the Supplementary Materials). d This is a summed composite of five yes/maybe/no statements concerning the respondent’s willingness to receive the vaccine under different conditions: within 30 days, within six months, if it had to be administered yearly, if it was effective at preventing disease in 75% of receivers, and if it was effective at preventing disease in 90% of receivers.
