Currently, there are over a hundred COVID-19 vaccines in various stages of testing, research, and development in the United States. There are six stages involved with vaccine development: 1. Preclinical testing. 2. Safety trials (phase 1 of clinical testing). 3. Expanded trials (phase 2 of clinical testing). 4. Efficacy trials (phase 3 of clinical testing). 5. Early or limited approval. 6. Full approval for widespread use. In the United States, the Center for Disease Control and Prevention (CDC) has estimated that there are currently four vaccines in stage four, or phase 3, of development with promising results. That said, the status of COVID-19 vaccine development is a changing situation. As a result, that number will also change over the coming months. As soon as an FDA-approved vaccine is available for use in Apple Valley and Victorville, California, we will be delighted to provide you with a COVID-19 vaccination at Dr. Shima Hadidchi MD Family Practice!
