WHO Approval Process: Steps and criteria the World Health Organization uses to approve vaccines like Abdala
The World Health Organization (WHO) has a rigorous approval process for vaccines, ensuring they meet international standards for safety, efficacy, and quality. This process involves several critical steps and criteria that must be satisfied before a vaccine, such as Abdala, can receive WHO approval.
Initially, the vaccine undergoes preclinical evaluations, which include laboratory research and animal studies to assess its potential safety and efficacy. Following successful preclinical results, the vaccine enters clinical trials, which are conducted in three phases. Phase I trials test the vaccine for safety in a small group of healthy volunteers, while Phase II trials expand the testing to a larger group to further evaluate safety and initial efficacy. Phase III trials are the largest, involving thousands of participants to confirm the vaccine's efficacy, monitor side effects, and compare it with commonly used treatments.
Throughout these trials, the WHO monitors the vaccine's development closely, ensuring that it adheres to Good Clinical Practice (GCP) guidelines. The organization also conducts on-site inspections of manufacturing facilities to ensure compliance with Good Manufacturing Practice (GMP) standards.
Once the clinical trials are completed and the vaccine is deemed safe and effective, the manufacturer submits a dossier to the WHO containing all the necessary data, including results from clinical trials, information on the vaccine's composition, and details about its production process. The WHO then convenes a meeting of its Strategic Advisory Group of Experts (SAGE) to review the dossier and make a recommendation on whether the vaccine should be approved for emergency use or full licensure.
If the SAGE recommends approval, the WHO's Director-General will make the final decision. Upon approval, the vaccine is included in the WHO's list of prequalified vaccines, which serves as a signal to countries that the vaccine meets international standards and can be procured for use in their national immunization programs.
In the case of the Abdala vaccine, developed by the Cuban Institute of Biomedical Research, it underwent this thorough evaluation process before receiving WHO approval. This approval is crucial for the vaccine's acceptance and distribution in various countries, particularly in regions where access to vaccines might be limited.
