What side effects are associated with this type of intervention?

Common side effects of influenza vaccines, including the Quadrivalent Influenza modRNA Vaccine, typically include mild to moderate reactions such as soreness at the injection site, headache, muscle aches, fever, and fatigue. These side effects are generally short-lived. Antiviral drugs like zanamivir and laninamivir, used for flu prevention and treatment, can cause gastrointestinal side effects and, in some cases, bronchospasm, particularly in individuals with a history of respiratory issues. Overall, these treatments are well-tolerated, with serious adverse events being rare.

What prior FDA approvals exist?

The FDA has approved several treatments for influenza, including antiviral drugs like oseltamivir (Tamiflu), zanamivir (Relenza), and baloxavir marboxil (Xofluza). These drugs work by inhibiting viral replication. While there are no FDA-approved influenza vaccines using modified RNA technology similar to the Quadrivalent Influenza modRNA Vaccine, the success of mRNA vaccines for COVID-19 (e.g., Pfizer-BioNTech and Moderna) suggests potential for future approvals in this area. Traditional flu vaccines, such as inactivated and live attenuated vaccines, remain the primary FDA-approved options for influenza prevention.

What other types of research exist?

Promising novel alternatives to the Quadrivalent Influenza modRNA Vaccine for flu patients in 2024 include: 1) Plant-based influenza vaccines, which utilize plant-based transient expression systems to produce virus-like particles that have shown safety and immunogenicity in clinical trials. 2) Adenovirus-based quadrivalent influenza vaccines, which have been modeled in animal studies and demonstrated favorable immune responses compared to traditional vaccines. Both alternatives represent innovative approaches in vaccine development and could offer effective protection against influenza.

Summary

This trial is testing a new type of flu shot that uses modified RNA to protect against four strains of the flu. It targets healthy adults aged 18 and older. The vaccine works by teaching the immune system to recognize and fight the flu virus.

Who is the study for?

Adults over 18 who are healthy and have had a recent colonoscopy can join this flu vaccine study. They must be able to follow the study plan and give informed consent. People with egg or chicken protein allergies, severe reactions to vaccines, or certain medical or psychiatric conditions cannot participate.

What is being tested?

This Phase 3 trial is testing a new quadrivalent influenza modRNA vaccine against the standard flu shot in adults. Participants will receive one dose of either the new vaccine or the standard one, and researchers will compare their effectiveness and safety.

What are the potential side effects?

Potential side effects from both vaccines may include pain at injection site, fatigue, headache, muscle pain, feverish feelings, joint pain; however specific side effects for the modRNA vaccine are not detailed as it's under evaluation.

Other Research

The quadrivalent influenza modRNA vaccine works by using modified RNA to instruct cells to produce antigens that trigger an immune response against four strains of the influenza virus. This approach helps the immune system recognize and fight the virus more effectively. Other common treatments include inactivated vaccines, which use killed virus particles, and recombinant hemagglutinin vaccines, which use viral proteins to stimulate immunity. These mechanisms are crucial for flu patients as they prepare the immune system to quickly identify and combat the influenza virus, thereby reducing the severity and duration of the illness.
