The labelling system (e.g.: package insert) of TYPHIM Vi (polysaccharide typhoid vaccine) indicates that any open vial remaining at the end of the immunization session (this is after 6 hours after first opening) should be discarded. The vaccine is presented in 20 doses liquid presentation with phenol as preservative, which has considerable advantages in developing country immunization programmes, especially in campaign settings, as they are economical, occupy less space in the cold chain, and in many settings are preferable from the administration view point as well. However, in this case, these potential advantages could diminish through potential wastage. The vial contains 20 doses which makes it prone to such wastage. Therefore, this makes the vaccine more suitable for campaign settings, and users must weigh the significance of potentially high wastage in the context of routine vaccination programmes.
