Besides being used in vaccines, viral vectors have also been studied for gene therapy, to treat cancer, and for molecular biology research. Scientists began creating viral vectors in the 1970s. How Viral Vector Vaccines Have Been Used During Recent Disease Outbreaks While COVID-19 vaccines were developed rapidly, all steps have been taken to ensure their safety and effectiveness. Food and Drug Administration (FDA) will make available for use in the United States (by approval or emergency use authorization) are those that meet these standards. Viral vector COVID-19 vaccines have been held to the same rigorous safety and effectiveness standards as all other types of vaccines in the United States. Viral vector COVID-19 vaccines are safe and effective. Any side effects from getting the vaccine are normal signs the body is building protection.

People get this protection from a vaccine, without ever having to risk the potentially serious consequences of getting sick with COVID-19.

At the end of the immune building process, our bodies have learned how to help protect against future infection with the virus that causes COVID-19.This response is similar to what your body does if you get sick with COVID-19, but is temporary. This triggers our immune system to produce antibodies and activate other immune cells to fight off what it is an infection. Our immune system recognizes that the spike protein does not belong there. Next, our cells display the spike protein on their surface.After the spike protein piece is made, our cells break down the vector virus and remove it. The spike protein is found on the surface of the virus that causes COVID-19. It enters the muscle cells and uses the cells’ machinery to produce a harmless piece of what is called a spike protein. The vector virus in the vaccine is not the virus that causes COVID-19, but a different, harmless virus.

First, viral vector COVID-19 vaccines are given in a muscle in the upper arm.Viral vector COVID-19 vaccines use a modified version of a different virus (a vector virus) to deliver important instructions to our cells.
