For children whose vaccinations for DPT were all delayed, the risk of developing asthma decreased by 60%.
Comment by Dr. Bill Pawluk
The fact that these immunizations are given at 2, 4, and 6 months of age indicates that if they were delayed by 2 or more months the decrease in the risk of the child developing asthma would decrease significantly. The risk of developing one of these diseases is minimal in the U.S. and the delay would not affect the child’s ability to attend school.
