How Does the Vaccine Approval Procedure Affect COVID-19 Vaccination Intentions?

How does the vaccine approval procedure affect COVID-19 vaccination intentions?

“…Second, Klüver et al (2021) report a strong within-person correlation between vaccination intentions against COVID-19 in hypothetical vignettes and actual subsequent vaccination decisions in German adults. Similarly, in Angerer et al (2022) we show that survey-reported intentions to vaccinate strongly correlate with revealed preferences for COVID-19 vaccination (i.e., acquiring information on how to sign up for a vaccination appointment). Third, Campos-Mercade et al (2021a) show that the reaction towards the experimental variation is similar between intentions and actual behavior.…”

Discrimination in the General Population

“…1 Background characteristics: Female, age in years, whether the decision maker has a family history of migration (one if either the decision maker or one of his/her parents was not born in Germany, zero otherwise), whether the decision maker is currently working (one if participants report being (self-)employed), highest school degree, conservative political party preference (elicited by asking which party decision makers generally sympathize with (leaning toward AfD, CDU/CSU, or FDP is classified as conservative political orientation), and equivalized household income corresponds to the reported household income divided by the equalized household size (equivalized household size is a measure of household size using a standard (equivalence) scale, the modified OECD scale, which gives a weight of 1 to the first adult in the household, 0.5 to each other person in the household aged 14 years or older, and 0.3 to each child under the age of 14.). 2 The survey comprised an incentivized experiment on cooperation (Angerer et al, 2023), played before the allocation task. In this cooperation experiment, participants played a prisoner's dilemma game with or without third-party punishment (between-subject design).…”

“…Besides the experiment on discrimination, we elicited participants' sociodemographic characteristics and political and economic preferences. The survey also included a second experiment on cooperation (Angerer et al, 2023). Participants played a prisoner's dilemma game with another survey participant (distinct from the receivers in the discrimination experiment), where the inclusion of third-party punishment was randomly determined.…”

Vaccine‐skeptic physicians and patient vaccination decisions

“…Angerer et al. (2023) show in a vignette experiment that the type of approval procedure significantly affects trust in a vaccine and vaccination intentions.…”
