The Pfizer mRNA Flu Vaccine Studies

mRNA vaccines have changed the way we fight infectious disease. Introducing Pfizer’s research program for investigational flu vaccines using mRNA technology.

The mRNA Flu Vaccine Studies

Few breakthroughs in modern medicine have been as important as vaccines. The use of vaccines prevents a wide range of infectious diseases, including the flu, in hundreds of millions of people around the globe.

Recent developments in mRNA-based vaccine technology may help to protect people from the flu and ongoing research will help us to learn more about investigational mRNA-based flu vaccines.

You could help make a difference by participating in flu vaccine research. It’s only with the help of people who volunteer for clinical trials that potential new vaccines can be developed. So, thank you for taking the time to learn more about our mRNA flu vaccine research studies.

About mRNA Vaccines

The immune system is the body’s natural defense against infections. Vaccines help the immune system recognize viruses and bacteria that may invade the body in the future.

Some vaccines contain a small amount of the virus or bacteria from the disease they are designed to help prevent. The virus or bacteria has either been killed or weakened so it cannot make a person sick. Other vaccines contain only a part of the germ from the disease.

The investigational vaccines being studied are mRNA-based vaccines, which do not contain any killed or weakened virus. mRNA vaccines work by telling your body to produce proteins that look just like certain parts of the virus. The immune system reacts to these proteins in a similar way to a real virus. As a result, certain immune system cells “remember” how to recognize these proteins quickly and fight the real infection if it happens in the future.
