vaccine trial

A vaccine trial is a carefully designed process to test a new vaccine’s safety and effectiveness before it’s approved for widespread use. It involves giving the vaccine to volunteers in phases, starting with small groups to check safety, then larger groups to see if it protects against disease. Researchers monitor participants for side effects and measure immune responses. The goal is to ensure the vaccine is both safe and effective for the general population. This process helps us trust that vaccines work as intended and are safe for everyone.
