No one likes to take their child for shots, but it is just something that has to be done. As a parent, you are the first advocate for your child, so it is important to be aware of any issues that might surface.
Sometime around the second birthday, most pediatric offices will switch the injection site for immunizations from the thigh to the arm. This may be because they believe that the child is old enough for the more convenient way to administer any shots. But there is good reason to ask the office if shots can still be administered in the thigh instead.
Many times the length of the needle used in immunizations is longer than the thickness of a child’s upper arm tissue and deltoid muscle. In fact, the CDC recommends that thigh injections be done for a child who is younger than six years old.
Muscle thickness and body fat can vary by child, of course, but in general in young children, the ability of the needle to over-penetrate when injected into the upper arm (or shoulder) is quite common. If the needle goes in to far, then there are two results that generate concern. The first is that the delivery of the vaccination (or medication) could be affected, and the second is that if the needle hits the bone, it could cause sever pain for your child. Neither of these outcomes is what you would wish.
Injection needles for children may also vary. Most offices will use either a 5/8, 7/8 or 1-inch needle. In general, a 7/8 needle is probably best for thigh injections. Girls generally have more fat under the skin than do boys, even at a young age.
A report of a study done in which upper arm scans were performed on children to gauge arm thickness was published in the medical journal, Pediatrics in August of 2008.
