Pertussis vaccine: mouse-weight-gain (toxicity) test
Developments in Biological Standardization
|January 1, 1977
Summary
Mouse weight-gain toxicity tests for vaccines like DPT are unreliable. Using a standard control vaccine, not saline, provides more valid conclusions for vaccine safety assessments.
Area of Science:
- Pharmacology
- Immunology
- Toxicology
Background:
- Current mouse weight-gain toxicity tests for vaccines are insufficient.
- Vaccine preparations can be adsorbed or non-adsorbed, complicating test interpretations.
Purpose of the Study:
- To evaluate the efficacy of mouse weight-gain toxicity tests for vaccines.
- To determine the optimal control substance for vaccine toxicity testing.
Main Methods:
- Comparison of toxicity test results using saline versus standard control vaccines.
- Assessment of adsorbed and non-adsorbed vaccine preparations.
Main Results:
- Mouse weight-gain tests are unsatisfactory for vaccine toxicity evaluation.
- Saline controls yield less valid conclusions than standard control vaccines.
Conclusions:
- Standard control vaccines (adsorbed and non-adsorbed) are superior to saline for vaccine toxicity testing.
- Improved methods are needed for reliable vaccine safety assessment.
