No vaccines should be wasted. All vaccination centres should have a backup list people in the cohorts currently being vaccinated, who can be called in case doses would be wasted. If no members of the currently vaccinated cohorts are available, it is recommended that members of the priority cohorts next in line be vaccinated.
In the unlikely case the above is not possible, and where the general practice can demonstrate exceptional circumstances showing that it is clinically appropriate and where resources would otherwise have been wasted, then individuals present on site should be vaccinated based on clinical judgement. This is in line with the Enhanced Service Specification for the COVID-19 vaccination programme 2020/21.
