Dr. Halsey's presentation at the National Vaccine Advisory Committee Workshop on Thimerosal and Vaccines held in Bethesda, Maryland on August 11-12, 1999.

Slide Notes:

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.
