Key Takeaways
- $5.0 billion global influenza diagnostics market size in 2023, supporting flu surveillance and testing expenditures.
- $3.6 billion global influenza vaccine market size in 2023 (with growth forecasts tied to seasonal demand and pandemic preparedness).
- $7.3 billion global influenza vaccine market size estimate for 2024 in a segment-focused industry forecast.
- 37% reduction in influenza illness among vaccinated individuals compared with unvaccinated in a pooled estimate across randomized and observational studies summarized by the Cochrane review evidence base.
- 39% reduction in risk of influenza-related medically attended illness in vaccinated people in a meta-analysis of observational studies (pooled effectiveness across seasons).
- 15% reduction in all-cause mortality among older adults in some meta-analyses is associated with influenza vaccination (range depends on study design and season).
- 50% of the population coverage achieved in targeted groups reduces influenza transmission in modeling analyses used by public health agencies (coverage sensitivity in transmission models).
- Vaccination reduces influenza-confirmed illness risk compared with placebo in randomized trials; a pooled relative risk reduction of about 59% is reported for children in older meta-analyses (evidence synthesis).
- 2.0–3.0 fold rise in post-vaccination antibody titers is used as a criterion for seroconversion in many influenza vaccine immunogenicity studies (endpoint used in trials).
- 38% of adults in the UK reported receiving a flu vaccine in the 2023–2024 season for eligible groups (NHS/UK uptake reporting).
- $2.0–$3.0 per dose wholesale cost range in some healthcare procurement contexts for trivalent influenza vaccines in recent procurement analyses (cost metric depends on country and formulation).
- $10–$30 per dose retail/pharmacy pricing range is reported in U.S. price research sources for influenza vaccine products (price varies by formulation and setting).
- 2%–5% wastage rate is used as an assumption in economic evaluations of vaccination programs in multiple published cost-effectiveness models (wastage assumption).
- In a 2021 peer-reviewed economic evaluation synthesis, influenza vaccination programs can be cost-effective with ICERs often below common willingness-to-pay thresholds in older adults and risk groups (cost-effectiveness synthesis quantitative results).
Flu vaccination reduces illness and hospitalizations while remaining cost effective, with benefits supported by major studies.
