The FDA's role in vaccine approval has evolved significantly over the years. Initially, the FDA did not have the authority to approve vaccines; this responsibility lay with the National Institutes of Health (NIH) and the Centers for Disease Control and Prevention (CDC). However, in 1972, the FDA was granted the authority to regulate and approve vaccines under the Federal Food, Drug, and Cosmetic Act (FFDCA). This marked a pivotal moment in the history of vaccine regulation in the United States, as the FDA began to oversee the safety, efficacy, and security of vaccines for human use. Since then, the FDA has worked to ensure that vaccines meet rigorous scientific standards before they are made available to the public.
