The development of a vaccine involves several key steps:
1. **Identification:** Scientists identify a target pathogen, such as a virus or bacteria, that causes a specific disease.
2. **Research and Pre-clinical Testing:** The potential vaccine undergoes laboratory testing and animal studies to assess its safety and effectiveness.
3. **Clinical Trials:** The vaccine is tested in three phases of clinical trials involving human volunteers to evaluate safety, efficacy, and dosage.
4. **Regulatory Approval:** Regulatory authorities review the trial data, and if satisfied, grant approval for the vaccine.
5. **Production:** Once approved, the vaccine is manufactured on a larger scale.
6. **Distribution:** The vaccine is distributed for public use, often prioritizing high-risk populations.
7. **Monitoring and Surveillance:** Continuous monitoring ensures the vaccine's safety and effectiveness in real-world conditions.
This process aims to provide a safe and effective vaccine for preventing specific diseases.
Each vaccine under development must first undergo screenings and evaluations to determine which antigen should be used to invoke an immune response. This preclinical phase is done without testing on humans. An experimental vaccine is first tested in animals to evaluate its safety and potential to prevent disease.
