I have Cigna and I can vouch for this also -- DS and I went back in August to the stand-alone clinic inside HEB, and we didn't pay a dime. Also, you don't have to get the actual flu shot, it also covers FluMist -- because unless you're outside the age range or have contraindications, why on earth would you volunteer to get a shot???

I wish every vaccine were offered intra-nasally!
