Adjuvanted Flu Vaccine for Flu
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial tests two types of flu vaccines to determine which better prevents the flu in older adults. One vaccine, known as aQIV or aTIV, includes an adjuvant, which may enhance the body's response, while the other does not. The researchers aim to discover if the adjuvanted vaccine is more effective for those 65 and older. Individuals who are 65 or older, not bedridden, and haven't recently received a flu shot may be suitable for this trial. As a Phase 3 trial, this study represents the final step before FDA approval, allowing participants to contribute to research that could lead to a new, effective flu vaccine for older adults.
Do I have to stop taking my current medications for the trial?
The trial does not specify if you need to stop taking your current medications. However, if you are taking certain medications like high-dose corticosteroids or immunomodulating agents, you may not be eligible to participate.
Is there any evidence suggesting that this trial's treatments are likely to be safe?
Research shows that the MF59-adjuvanted flu vaccine is generally safe. Studies indicate that serious side effects are rare, though some individuals might experience a mild to moderate fever more frequently with this vaccine. The vaccine triggers a strong immune response, indicating its effectiveness. People with severe allergies to flu vaccines or certain ingredients should avoid this vaccine. Overall, evidence suggests this vaccine is safe for most individuals.12345
Why do researchers think this study treatment might be promising?
Researchers are excited about these treatments because they use an adjuvant, MF59, which boosts the immune response to the influenza vaccine. Unlike standard flu vaccines that don't contain an adjuvant, these adjuvanted vaccines may provide enhanced protection by stimulating a stronger immune response. This approach is particularly promising for those with weaker immune systems, like the elderly, as it could lead to better efficacy and broader protection against the flu.
What evidence suggests that this trial's treatments could be effective for flu prevention in adults ≥65 years of age?
Research has shown that the MF59-adjuvanted flu vaccine (aQIV or aTIV), which participants in this trial may receive, offers better protection for older adults than regular flu vaccines. Studies have found that this vaccine reduces the likelihood of hospital visits due to the flu and other respiratory issues. It performs as effectively as high-dose vaccines in preventing the flu for those aged 65 and older. The vaccine contains an adjuvant that enhances the body's immune response, offering stronger protection. This is particularly important for older individuals, whose immune systems may not respond as effectively to standard vaccines.36789

Are You a Good Fit for This Trial?
This trial is for adults aged 65 or older who are willing to give written consent and can follow the study procedures. It's designed to see if a new adjuvanted flu vaccine works better than the regular non-adjuvanted one.Inclusion Criteria
Timeline for a Trial Participant
Screening
Participants are screened for eligibility to participate in the trial
Vaccination
Participants receive either the MF59-adjuvanted or non-adjuvanted influenza vaccine
Follow-up
Participants are monitored for RT-PCR-confirmed influenza and immunogenicity
What Are the Treatments Tested in This Trial?
Interventions
- aQIV or aTIV
Trial Overview
The study compares an MF59-adjuvanted influenza vaccine (either aQIV or aTIV) with a standard, non-adjuvanted flu vaccine (QIV or TIV). Participants will be randomly assigned to receive one of these vaccines in order to test effectiveness against the flu.
