"Fortunately, scientists began studying vaccine hesitancy long before Sars-Cov-2 was first identified in Wuhan in December 2019, and they have explored various models which attempt to capture the differences in people's health behaviour. One of the most promising is known as the 5Cs model, which considers the following psychological factors:
Confidence: the person's trust in the vaccines efficacy and safety, the health services offering them, and the policy makers deciding on their rollout
Complacency: whether or not the person considers the disease itself to be a serious risk to their health
Calculation: the individual's engagement in extensive information searching to weigh up the costs and benefits
Constraints (or convenience): how easy it is for the person in question to access the vaccine
Collective responsibility: the willingness to protect others from infection, through one's own vaccination."
