Are some vaccines more painful than others?
If you have administered vaccinations previously you may be aware that there are some vaccines that are thought to be more painful than others. You may have even possibly heard one of the following phrases from one of your vaccine recipients:
“wow, I didn’t feel that one at all”
“ouch, that one really hurt”
“that one left me with a really dead arm for days”
So what is it that causes the pain from a vaccination? and why is it that some vaccines are possibly perceived as being more painful, and others may hardly hurt at all?
