Sure thing. In 2023 about 48% of adults got the flu shot, and it cuts hospitalizations by roughly 40%. For high‑risk groups it lowers mortality by up to 70%. The average cost‑savings per dose is around $20 when you factor in avoided medical visits. Side effects are usually mild—like a sore arm or low‑grade fever—show up in 5‑10% of people. That should give your alley a solid evidence base.
