Summary

This trial is testing a new flu vaccine called mRNA-1010 in people aged 50 and older. The vaccine uses mRNA to help the body build immunity against the flu. The goal is to see if it is safe and effective in preventing the flu in this age group.

Who is the study for?
Adults aged 50 and older who can follow the study's procedures are eligible for this flu vaccine trial. Women of childbearing age must have a negative pregnancy test, use contraception, or abstain from sex to prevent pregnancy during the study. People with recent flu infections, blood donations, immunodeficiencies, severe allergies to vaccines or their components, recent exposure to influenza or COVID-19, or those on certain immunosuppressants cannot participate.
What is being tested?
The trial is testing mRNA-1010 Seasonal Influenza Vaccine against an approved quadrivalent inactivated seasonal influenza vaccine in adults over 50. The goal is to see if mRNA-1010 is safe and effective at preventing the flu compared to the standard vaccine.
What are the potential side effects?
Potential side effects may include typical reactions seen with vaccines such as soreness at injection site, fatigue, headache, muscle pain, feverish feelings which are usually mild and resolve within a few days.

Other Research
The most common treatments for influenza include antiviral medications and vaccines. Antiviral medications, such as oseltamivir, work by inhibiting the neuraminidase enzyme, preventing the virus from spreading within the body. Vaccines, particularly mRNA-based vaccines like mRNA-1010, function by encoding viral proteins that stimulate the body's immune system to recognize and fight the influenza virus. This is crucial for flu patients as it helps in building immunity, reducing the severity of the disease, and preventing complications. The mRNA vaccines are particularly significant because they can be rapidly developed and updated to match circulating viral strains, offering a robust and adaptable defense against seasonal influenza.
