The trial's reported rates were 2.0% (mRNA-1010) versus 2.8% (standard-dose) in CIDRAP and Reuters-based coverage, so a 0.8-point absolute reduction matches the record within rounding. Recomputing from the raw counts (411/20,179 vs 557/20,124) gives about 0.73 points, which is close, and the post's "almost nothing" characterization is opinion that the extracted claim does not repeat.

What was said

… purposely used an antiquated old one to make it look better, and they got a warning, basically a letter from the Biden administration saying, This isn't a great study design. They've been warned on it, so that was one issue. The second is it didn't work. It had a 0.8% absolute risk reduction, which is almost nothing, and a significant side effect profile based on the clinical trials. So they weren't even comparing to the standard of care, even though they rigged the study. …

What we found

Supports. CIDRAP reports the trial results as 2.0% of 20,179 mRNA-1010 recipients contracting flu versus 2.8% of 20,124 standard-dose recipients, a difference of 0.8 percentage points.[2]

Supports. Reuters and the NEJM-based coverage report the same trial population and efficacy result (26.6% relative vaccine efficacy), which the rates above translate into an absolute difference.[1][3]

Supports. A People's Pharmacy analysis of the raw counts (411 of 20,179 vs 557 of 20,124) gives roughly 2.0% vs 2.8%, and a Substack calculation gives about 0.73 percentage points, which is close to 0.8 once rounding of the reported rates is accounted for.[4][5]

Context. The precise difference from unrounded counts is about 0.73 points, and the claim's 0.8% matches the rounded published rates rather than the exact calculation; coverage of the figure is limited to a few sources and one low-credibility outlet repeats it.[5][6]
