Summary

This study looks at whether giving pregnant mothers extra vitamin D can prevent asthma symptoms like wheezing in their children. About 600 mothers from a Danish asthma study take either a high dose of vitamin D or a placebo daily from week 24 of pregnancy until one week after birth. The children are then monitored for several years to see if they develop asthma.
