But after 12 days, vaccinated people saw their average viral loads decrease, suggesting the vaccine is driving the reduction. A lower viral load may mean that they are less likely to infect others with the same efficiency that an unvaccinated person may. "The virus shedding and viral organ load were considerably reduced in both the two dose and three-dose immunised animals indicating the vaccine efficacy against Delta variant," the study added. This study confirms that COVID-19 vaccination reduces the risk of delta variant infection and also accelerates viral clearance in the context of the delta variant. The short answer seems to be yes.
