Study Notes
Biological License Application (BLA)
- Includes pre-clinical and clinical data, details about the manufacturing process, and information about the manufacturing facility
- Contains prescribing information, which includes vaccine usage, dosage, and administration based on scientific data
- Can be updated, and FDA will review the updates
Vaccine Approval Process
- Phase 1: Small group (20-100) clinical trial to test safety, identify side effects, and determine dosage
- Phase 2: Clinical trial with hundreds (100-300) of participants to provide additional safety information and monitor immune response
- Phase 3: Clinical trial with thousands (1,000-3,000) of people to confirm vaccine effectiveness and monitor side effects
Post-Approval Monitoring
- Phase 4: Ongoing study to evaluate vaccine safety and effectiveness over a longer period
- Continuous monitoring of vaccine impact and safety after introduction
- Data used to adjust vaccine use policies and optimize impact
Vaccine Classifications
- Live Attenuated/Weakened Vaccine
Vaccine Components
- Adjuvants: improve immune response, may include aluminum salts
- Antibiotics: used to prevent bacterial contamination during manufacturing
- Surfactants: keep ingredients blended and prevent settling
- Diluent: liquid used to dilute vaccine to correct concentration before use (usually sterile water)
Vaccine Testing and Approval
- Extensive and rigorous testing to ensure safety before introduction into a country's vaccine program
