Analysis of Social Combinations of Coronavirus Vaccination: Evidence from a Conjoint Analysis

Using a conjoint analysis based on cases in Japan, this study attempts to identify a preferable social strategic combination of “Who is vaccinated, who is not, who waits.” The analysis shows that the most desirable choice is a “wait-and-see” strategy, allowing for a risk assessment of side effects. We also find that subjects who recalled blood relatives as their familiar entities tend to prefer a “wait-and-see” strategy for themselves and their blood relatives.
