Vaccine Approval Process

The vaccine approval process involves several steps to ensure safety and effectiveness. First, researchers develop the vaccine and conduct laboratory tests. Then, they perform clinical trials in phases: small groups for safety, larger groups for effectiveness, and even larger for confirming results. Regulatory agencies, like the FDA, review trial data to assess benefits and risks. If the vaccine meets strict standards, it receives approval or emergency use authorization. After approval, ongoing monitoring continues to ensure safety. This thorough process helps provide public confidence in vaccines' safety and efficacy.
