Clues to how the three available Covid-19 vaccines compare could come through a real-world study on the long-term effects of inoculation, offering a chance to subdue fears over whether one shot is better than another.
Thousands of health-care workers will be surveyed in the next few years on their health and well-being as part of a study known as âHERO-Together.â The first phase of the study, led by the Duke Clinical Research Institute, will address vaccine hesitancy, but over time it will also address safety and health outcomes, with the potential to determine whether there are any meaningful differences among the vaccines.
