Several different vaccines have been developed for COVID-19. A few of them have made it through clinical trials and have been approved by the U.S. Food and Drug Administration (FDA). Some are still in clinical trials. Of the vaccines approved for use in the U.S., between 30,000 to 45,000 participants enrolled to participate in each study.

No, none of the approved COVID-19 vaccines contain the live virus and cannot give you COVID-19.
COVID-19 vaccines teach our immune systems how to recognize and fight the virus that causes COVID-19. Sometimes this process can cause symptoms, such as fever. However, building immunity from a vaccine is a much safer option and these symptoms are normal signs that the body is building protection against the virus that causes COVID-19.

No. However, it typically takes a few weeks to build immunity after receiving a vaccine. That means it is possible a person could be infected with the virus that causes COVID-19 just before or just after vaccination and still get sick. In this case, the person would test positive for COVID-19 shortly after getting the vaccine.
The protection someone gets from having an infection, called natural immunity, varies depending on the disease and from person to person. Since this virus is new, it is unknown how long natural immunity will last. As experts continue to study both the virus and the vaccines, we will continue to learn more. However, building immunity from a vaccine is a much safer option than to risk the complications from becoming ill from COVID-19.
