Becky,
Check with your pediatrician. Haley may have already received a vaccine to cover pneumococcal pneumonia. I went through this a couple years ago with my ped. Maggie had gotten a series of vaccines called Prevnar, which covers most of the pneumococcal stuff(someone correct me if I'm wrong.) Anyhow, I'm sure when she's an older CF'er she'll need the pneumovax shot which is good for 5 years.
