 This study found that university students in China have a strong intention to get the COVID-19 vaccine either for free or at their own expense. However, those who are willing to pay for the vaccine are less likely to do so if they perceive it as a burden. Prosociality and social responsibility were also found to be associated with the intention to get the vaccine. These findings suggest that modifying prosociality and social responsibility could help increase the number of people getting the vaccine.
