An mRNA (messenger ribonucleic acid) influenza biologic developed by Moderna, Inc. is scheduled to be reviewed today by a U.S. Food and Drug Administration (FDA) advisory panel. The Vaccines and Related Biological Products Advisory Committee ((VRBPAC) will evaluate data on Moderna’s mFlusiva (formerly known as mRNA-1010) to determine if the product provides superior relative vaccine efficacy versus a standard-dose flu vaccine in adults aged 50 to 64. It would vote on whether the benefits of mFlusiva outweigh the risks in adults 50 years and older.1 2 3 4
Additionally, Moderna is seeking accelerated FDA approval of mFlusiva for adults 65 and older.2
A Reuters news release cites Jefferies Group financial analyst Andrew Tsai as saying he believes the assessment for mFlusiva looks “favorable.”2
Limitations in the Safety and Efficacy Data
However, there are limitations in the data for mFlusiva that may create roadblocks for a favorable decision on the product. For one, there is the fact that the biologic has only been studied during one influenza season. In an article for PharmExec.com, Nicholas Jacobus notes this “leav[es] open how the vaccine would perform against different circulating strains in future years.”2 5
Another limitation in the data is that immunocompromised individuals and very frail older adults were not included in the clinical trials for the product—two groups which Jacobus points out are at the “highest absolute risk of severe flu-related complications and those most likely to respond differently to mRNA-based vaccine platforms.”2 5
Also, the accelerated approval application for mFlusiva for those 65 and older is based on immunogenicity data for the shot against a standard-dose flu shot, rather than high-dose, recombinant, or adjuvanted influenza vaccines preferred by the U.S. Centers for Disease Control and Prevention (CDC).2 5
Lastly, there is the problem of a lack of data on co-administration of mFlusiva with other routinely recommended respiratory vaccines such as COVID-19, RSV (Respiratory Syncytial Virus), and pneumococcal vaccines. No safety studies have been done on the health impacts of administering mFlusiva to patients who have also received one or more of the other shots.5
FDA scientists who have reviewed the data for mFlusiva have reportedly highlighted that these limitations “lower the applicability of the efficacy data to a substantial portion of the intended patient population.”5
mFlusiva Could Be the First mRNA Flu Shot
A decision by the FDA on mFlusiva is expected to be made by Aug. 5, 2026. If the licensure application for the experimental biologic is approved, it would make mFlusiva the first mRNA-based seasonal flu shot in the United States.2 5

STOP mRNA anything!!!!
More death shots for our seniors. Do the so called “clinical trials” even include the cohort?
How much proof do these fools in HHS/FDA/CDC/NIH need to convince them they are killing and/or disabling millions of people. When the cure is worse than the disease the cure needs to be ended. mRNA has been proven not to be safe for humans. It was proven not to be safe for humans even before COVID. We can only logically assume this is part of their satanic depopulation agenda.
NO MRNA IN VACCINES,PERIOD!!!
It’s a 1,000% certainty it will be approved and with no substantial trials. As a senior, I have not had any vaccines in over 50 years. There is absolutely no reason to have these poisons injected into ANYBODY.
I am with you Tom. The last vaccine I had was when I was 10 years old. It was the polio liquid vaccine and it was given to us at school. We had no choice but to line up and follow the crowd. I am 81 now and I have not been to a doctor since 1994. I have no aches or pains and I am never sick so why would I need a doctor.
I hear you. I’m also very frustrated with allopathic physicians who believe in vaccines. I recommend you to check out a homeopathic provider as well as a chiropractor who share your philosophy. But I have heard chiropractors who took Covid jabs sadly. So stay alert.
the original flu shots were killing seniors, this one must do it better.
They just can’t quite seem to develop a comprehensive testing method for all vaccines all the time. Curious…
Definitely has nothing to do with the entire vaccine program being a money making scam which has persisted centuries since the mid 1800’s.
FDA will actually review nothing, take the money, and approve whatever they’re told to approve.
Repeat after me; Safe AND Effective.
Reading the never ending faux science does however really help with an expanded vocabulary. Bedazzling the masses often requires really big words!
Try this one out instead; Soap, clean filtered water, rest, vitamin c & d, red meat, iron, teas, herbs, and a can do positive attitude. Or be a hopeless hypochondriac living your entire live mentally tied to the grave yard, blindly trusting complete strangers whom only see you as a money making resource instead. Your choice. They’re standing by to harvest your illness and monetize it for glorious profits.
THEY have learned NOTHING regarding the murder and maiming of
so many who foolishly stepped up for the mRNA jab early in ’20
Very much agreed with you!! I’ve tried to tell them just to do the research first but didn’t listen to me. That was their loss. 🤷🏻♀️
