Slide 24 of 26
Manufacturers should be encouraged to use unit dosing
for vaccine delivery whenever possible. Not only does this
preclude the need for preservatives such as thimerosal, but
this can eliminate errors from improper reconstitution or
mixing of vaccines. Although these errors occur
infrequently, they can be harmful. There are drawbacks to
unit dosing, including increased refrigerator space
requirements, but newer developments may reduce space
requirements. There are also increased costs associated with
unit dose delivery, which will need to be addressed.
