Unfortunately, the nasal spray is still cultured in egg. I asked when it first came out, and the pharmacist mentioned when I talked to her earlier this week that it still is.
Basically, egg is a really cheap and reliable medium for culturing such things. There isn't a perceived demand for a vaccine cultured in another way, so nobody's looking for alternatives.
