Shortage of multiple vitamins for infusion

The American Society of Health-System Pharmacists reports a shortage of multiple vitamins for infusion. The key to this shortage seems to be that the shortage of adult MVI leads to a shortage of pediatric MVI because the latter are used for adults instead of for children less than 2.5 kg or less than 36 weeks gestational age. I infer this from the bulletin's statement:

Use of pediatric intravenous multivitamins for adults is not recommended and may result in a shortage of pediatric products

The bulletin also gives another hint at the problem by listing an alternate supplier, Baxter, for both pediatric and adult MVI. Evidently multiple suppliers is not enough to solve the problems caused by manufacturing delays at Hospira. 

Am I interpreting this situation correctly? Comments are welcome.
