 This study found that 56 percent of people in Portugal are hesitant about getting the COVID-19 vaccine, while 9 percent outright refused it. Factors such as age, income loss during the pandemic, lack of intentions to get the flu vaccine, lower confidence in the government's response to the pandemic, and poor perception of information provided were all associated with both refusing and delaying the vaccine. The authors suggest that governments and health authorities need to work on building trust and improving communication to reduce hesitance around the vaccine.
