Vaccine development is the scientific process of creating vaccines to prevent infectious diseases. This involves several stages, including basic research to understand the pathogen, preclinical trials to assess vaccine candidates in laboratory settings or animal models, and clinical trials that evaluate safety and efficacy in human subjects. Vaccine development typically follows structured phases: Phase 1 focuses on safety and dosage, Phase 2 assesses immune response and further evaluates safety, and Phase 3 involves large populations to confirm efficacy and monitor adverse reactions. Successful vaccine development can lead to immunization strategies that reduce disease transmission, morbidity, and mortality, ultimately contributing to public health. The process can be influenced by scientific advancements, regulatory requirements, and resources available.
