Usually, the vehicle used for a intramuscular drug contains oil or a "fatty liquid". The amount of liquid injected is generally bigger in an IM injection and the drug might also be more irritative. The nail used is generally bigger and longer.

For these reasons, almost all IM injections are more painful than SC injections.

Is the meningitis shot worse or less than dtap?

Vaccinations can be given in several ways, usually either intramuscular or subcutaneously. The different methods of injection will cause a different pain-experience in different people. I personally have always found subcutaneous injections more painful than intramuscular injections, but have heard other people say the contrary. The actual injected material won't have any effect on the experience, because all vaccines - especially mainstream ones like these - are designed to only prepare the immune system for the arrival of the actual virus, by triggering it with a non-functioning version of the virus. When the real deal comes along, the body will remember what to do from the vaccination and can deal with the virus with the prepared immune system. The only possible negative from a vaccination, apart from the injection, can be a bad reaction from the body, like a light fever. This is rare and usually passes quickly, but it would be wise to seek council from the organization which administered the vaccine.
