The abstract instead shows mixed male-to-female ratios by age and subtype, with some adult groups below 1.0 and no statistically significant sex differences reported for type/subtype-associated hospitalizations. So the exact overall claim is not directly established. False: The evidence supports that a US military-linked study involved more than 1,000 adults (1,114) and reported that women given a half dose had geometric mean antibody titers about the same as men given a full dose. But the participants were enrolled and vaccinated in fall 2004, not in 2008. The results were reported/published in 2008, so the claim’s date for the vaccination event is wrong. Misleading: One source says nearly 78%–80% of autoimmune disease patients are women, which supports the 'other autoimmune diseases' part. But the lupus-specific source says men are only 4%–18% of lupus patients, meaning women are about 82%–96% of cases. So applying an 'approximately 80%' figure to 'people with lupus or other autoimmune diseases' blurs an important difference: lupus is typically even more female-skewed than autoimmune disease overall.","claims":[{"claim":"A multi-year study in Hong Kong found more men than women hospitalized for influenza.","assessment":"unverifiable","why":"The Hong Kong study covered 2004–2010 and analyzed age- and sex-specific excess influenza-associated hospitalization rates, but the provided evidence does not report an overall total showing more hospitalized men than women.
