Controversies could fuel COVID-19 vaccine hesitancy
Significance Scientists and governments are increasingly concerned that ‘vaccine hesitancy’, the situation of people delaying or refusing some or all vaccines, could reduce immunisation against COVID-19. Impacts Due to initial scarcity, vaccine access will not be on an equal basis, both within and across countries, impacting perceptions of fairness. Vaccination certificates for travel, entering public spaces or for certain professions will be increasingly debated. Adherence to handwashing, mask-wearing and social distancing norms will be needed for some time, even with COVID-19 vaccines.
