Understanding what the results from COVID vaccine trials mean for the pandemic.
Getting a COVID-19 vaccine can help keep you from getting seriously ill.
The vaccines create an immune system response, which is a safe way to build protection from the virus. Vaccines help protect you and those around you, and they are an important tool to help stop the pandemic.
The COVID-19 vaccines have been through every stage of clinical trials that would normally take place for a vaccine. The U.S. Food and Drug Administration (FDA) followed all required steps, and the Centers for Disease Control and Prevention (CDC) and the Advisory Committee on Immunization Practices have been actively involved in the evaluation process.
More than 43,000 people across all demographic groups participated in the Pfizer vaccine clinical trial, and more than 30,000 people participated in the Moderna clinical trial. Clinical trials show that the Pfizer and Moderna coronavirus disease 2019 (COVID-19) vaccines are about 95 percent effective at preventing people from getting sick with COVID-19.
