Today's flu vaccines are updated each year to prevent infection with the specific strains of the flu that scientists and health officials expect to be common that year. It takes several months to make the vaccines and their effectiveness depends on how well they match the strains of the flu virus that are circulating.
Recent advances in mRNA-based vaccines, like the COVID-19 vaccine, have taught us more about how mRNA technology can be used to develop vaccines. mRNA vaccines take less time to make. This means it could be easier to produce vaccines each season that are better matched to the most common flu strains.
The creation of the COVID-19 vaccine made history. Could you help us try to do it again with flu?
This study will help us learn if an investigational vaccine is safe and can help the body produce antibodies which may help fight off the flu. The investigational vaccine is thought to work by activating your immune system using mRNA. There is no weakened or dead flu virus in the investigational vaccine.
Your participation in this research study will not only help advance a potential new type of flu vaccine, but will support investigational vaccine development for other infectious diseases. So, thank you for taking the time to learn more.
This study is enrolling people who:
- Are at least 65 years old
- Are generally healthy or have stable chronic conditions
- Have not received an investigational or licensed flu vaccine in the last six months
This study will include people from two different age groups — 18 to 64 and 65 or older. We are currently accepting referrals who are 65 or older and invite you to complete our online questionnaire to see if you may be able to participate.
While everyone needs to be represented in vaccine clinical studies, it is especially important that these vaccine studies include people from the communities most significantly impacted by the flu. By choosing to volunteer, you will represent people like you — in age, sex, race, and ethnicity and from communities like yours. Involving people from all backgrounds will improve the development of this investigational vaccine for everyone. By volunteering for a flu vaccine study, you can make a difference.
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 vaccine being studied is a mRNA vaccine, which does 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.
