One of the challenges for any vaccine that can effectively stop the spread of COVID-19 is the question of whether people will actually take it. Surveys and reports in multiple countries show many people are hesitant to accept a new vaccine, and some are already determined not to take anything to stem COVID-19. The reasons for this include broad vaccine scepticism, and the heightened uncertainty as the media reports on the accelerated pace of vaccine research and development in ways that are not necessarily comforting for a public anxious about related risks. Some people will be persuaded of the value of the vaccine once they have clear evidence of its effectiveness and safety, but others have lost too much trust in authorities amid a generally inadequate global COVID-19 response.
