Pooling residual vaccine does not meet best practice because: 1 Single use vials are highly recommended to reduce infection risk. 2 Multidose vials if used involves specific handling to reduce risk of infection, like labeling with clients name and date of first dose, if vials are open and mixed this increases risk of contamination and each vial may also have been opened at different dates and expiry date may differ. This changes the efficacy of the vaccine.
