COVID-19 vaccine development

COVID-19 vaccine development involves several steps: identifying parts of the virus that trigger immune protection, creating vaccine candidates, and testing their safety and effectiveness through multiple clinical trial phases. The process accelerates traditional timelines by overlapping stages without skipping safety checks, utilizing existing technologies and global collaboration. Once a vaccine proves safe and effective, regulatory agencies review data for approval. Manufacturing then begins at scale to distribute widely. The goal is to quickly provide strong protection against COVID-19, reducing illness, hospitalizations, and transmission.
