From Germany to the Dominican Republic, government health authorities are recommending the "mix-and-match" approach to vaccination in the hope of better protecting people by giving people them two different types of vaccine -- one as a first dose, and another as a second or even a third dose.
But does it really protect people better, and is it even necessary? From a scientific point of view, the jury is still out. Studies are currently underway to better understand the risks and benefits of mixing coronavirus vaccines -- which might ease logistical problems for some global vaccine programs. But more research is needed to see whether mixed vaccine schedules work in the real world.More Related News
