There is always lots of debate about pediatric vaccinations. The latest study from Pediatrics tells us that the needle length that has been recommended by the Centers for Disease Control (CDC) is wrong and in many cases IS TOO LONG.
The CDC has recommended needles up to 1-1/4 length, which would result in over penetration in a high percentage of babies and children, especially for injections in the shoulder. By looking at MRIs and evaluating the depth of the subcutaneous fat and muscle layers, these authors recommend much smaller needles and basing the size on the child's weight and age rather than using a universal needle length.
Isn't it amazing that this has not been studied before by the CDC? As the top regulatory agency, it is just assumed that their recommendations are based on science. Assume nothing!
I'm always gratified when actual scientific studies confirm what any mother could have told you just by common sense and sight. Don't be afraid to look at that needle length for your baby or toddler and make sure it fits the new recommendations.
