Acceptance and willingness to pay under the different COVID-19 vaccines: A contingent valuation method.
Article in Research in social & administrative pharmacy : RSAP, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundThe COVID-19 vaccine is recognized as a novel tool in the battle against COVID-19. Recently, there were several types of vaccines that have a different effectiveness and safety profile. Understanding the vaccine acceptance and willingness to pay (WTP) are essential to develop a strategic plan to increase the rate of COVID-19 vaccination uptake.
objectivesTo assess the acceptance and WTP for a COVID-19 Vaccine in Thailand using the contingent valuation method (CVM). Additionally, to identify the factors that affect the acceptance and the amount of WTP for a COVID-19 Vaccine.
methodsWe conducted a cross-sectional survey using a payment card approach with open-ended questions during September 2021. Three hypothetical COVID-19 vaccines (Vaccines A, B, and C) in two scenarios were employed. Data were collected from 752 people. Multivariate logistic regression was performed to assess the predictors of vaccine acceptance. Multiple linear regression was used to analyze factors associated with the maximum amount WTP for a vaccine.
resultsOf 742 respondents, the highest acceptance was vaccine C (70.71%), followed by B (17.72%) and A (11.57%). Similarly, 53.87%, 41.44%, and 36.21% of the respondents expressed WTP for vaccine C, B and A, respectively. The maximum amount WTP for vaccine C was US$46, followed by B (US$35) and A (US$32). Factors affecting acceptance included monthly salary, region of residence, education, perceived risk of COVID-19 infection, knowledge and attitude about the COVID-19 vaccine. In addition, monthly salary, region of residence, education and knowledge on COVID-19 vaccine were related to maximum amount WTP.
conclusionAcceptance and WTP depends on vaccine characteristics. Educational campaigns should be implemented to improve people's awareness, knowledge, and attitude towards COVID-19 vaccines to increase the vaccines' acceptance. To increase the rate of vaccination, the Thai government needs to allow freedom of choice on vaccines, while considering effectiveness and safety issues.
