- Understanding How COVID-19 Vaccines Work | CDC
The vector virus in the vaccine is not the virus that causes COVID-19, but a different, harmless virus It enters the muscle cells and uses the cells’ machinery to produce a harmless piece of what is called a spike protein The spike protein is found on the surface of the virus that causes COVID-19

Once inside, they use the cells’ machinery to produce a harmless piece of what is called the spike protein The spike protein is found on the surface of the virus that causes COVID-19 After the protein piece is made, our cells break down the mRNA and remove it, leaving the body as waste
- Myths and Facts about COVID-19 Vaccines | CDC
The mRNA vaccines do not contain any live virus Instead, they work by teaching our cells to make a harmless piece of a “spike protein,” which is found on the surface of the virus that causes COVID-19 After making the protein piece, cells display it on their surface
- Explaining How Vaccines Work | Vaccines Immunizations | CDC
The updated COVID-19 vaccines were developed to deal both with fading immunity and a fast-evolving virus
- Overview of COVID-19 Vaccines | CDC
Viral vector vaccines use a harmless, modified version of a different virus (a vector virus), and not the virus that causes COVID-19 The vector virus delivers important instructions to our cells on how to recognize and fight the virus that causes COVID-19
- Vaccine Glossary | Vaccines Immunizations | CDC
A vaccine that uses a modified, harmless fraction of a different virus (a vector virus) associated with an antigen that can induce production of important instructions that are delivered to the body’s cells
- How Influenza (Flu) Vaccines Are Made | Influenza (Flu) | CDC
To make a recombinant vaccine, flu scientists first obtain the virus' gene that contains the genetic instructions for making the HA HA is an antigen, which is a feature of an influenza virus that triggers the human immune system to create antibodies that specifically target the virus
- Kinds of E. coli | E. coli infection | CDC - Centers for Disease . . .
Most E coli are harmless and are part of a healthy intestinal tract These E coli help digest food, produce vitamins, and protect us from harmful germs But some E coli can make people sick, including six kinds that cause diarrhea
