Below you will find a summary of the approved influenza shots for this coming season. We found no material changes to the culturing method used for any of the approved vaccines, all of them using embryonated chicken eggs, specific pathogen-free eggs, MDCK canine cell lines or Sf9 insect cell lines as culturing media. None of the shots listed use mRNA in any way and none are combination vaccines for COVID-19. These are in development but have not yet cleared trials and been approved. It is not likely to happen this year. Like last year, none of the approved influenza shots are ethically compromised.
Here’s the chart:
Thank you and God bless all your hard work for others.
Thank you for this update. Please keep these updates coming on all the vaccines. Thank you.

Once a true vaccine (one designed to confer immunity) is approved, they are not re-developed, modified or otherwise updated. The influenza shots and the COVID-19 ‘vaccines’ are in a different category, as they deal with diseases that are endemic and the viral targets are subject to mutations. The recent changes to the COVID-19 booster are consistent with this. The ‘vaccine’ was not redeveloped, rather the mRNA coding for a specific antigen was changed to reflect the expected dominant strain.
Really appreciate all you guys do.
Hello, thank you for all the work that you do. I was told by my NP last fall and then again by an MD I follow that the mRNA is in the flu shots now. I was wondering if you would share your source(s) indicating that the flu shots are free of mRNA. Thanks again for your important work.
Dave, either you have been misinformed or the FDA is outright lying. The information that went into the summary was sourced from FDA documentation on the currently approved influenza vaccines. The source is noted at the bottom of the chart, and here’s a link to the page. The documentation clearly identifies the viral composition, and the culturing medium used for every one of the influenza shots. mRNA designs do not require a culturing medium or attenuated viral ingredients.
My assessment – the NP and the doctor are misinformed. Consider the cost associated with the investigation, testing and approval of a new drug, which is what an mRNA flu vaccine would be. Development and pre-clinical testing are not a laughing matter from a cost and time perspective and clinical trials (required for a new drug) are even more expensive and time-consuming. We’re talking about influenza shots, here. The market is well served (to the point of saturation) by inexpensive generics and a new drug would enter that market at a much higher price point. A pharmaceutical company has no incentive whatsoever to invest significant resources in something like this. They’ll never recover the investment.
Thank you so much
Thank you so much
Hello, thank you for all your efforts to gather this information. Last fall I had an NP tell me that the mRNA is in the flu shots and this summer an MD I follow said that mRNA is now in the flu shots. Can you share your source(s) indicating that the 2024-2025 is mRNA free? Again, thank you for the great work you do.
