🫀Are patients with atrial fibrillation better protected with high-dose influenza vaccines?
New study by @Espersen_C & @CTCPR_ (@ACCinTouch) using DANFLU-2:
- n=332,438 adults ≥65 years
- 34,085 (10.3%) with AF
- Randomized to high-dose vs standard-dose influenza vaccine across 3 seasons
🔑Key findings:
AF patients had markedly higher risks of influenza-related & cardiovascular hospitalizations
High-dose vaccine ↓ hospitalizations for:
- Cardiorespiratory disease
- Influenza (incl. lab-confirmed)
- Cardiovascular disease
Effects consistent regardless of AF status
Greater absolute benefit in AF (NNV ~243 vs ~933 in non-AF)
Worth noting:
The trial was not powered for the AF subgroup analyses, meaning these findings should be considered hypothesis-generating.
Implication:
In high-risk populations like AF, vaccine choice—not just vaccination—may matter 🫀
