Why is immunization taken on the upper arm swollen after a long period of time
Soreness, redness, and swelling where the vaccine was given is a common harmless side effect of vaccines but will generally subside after a day or two. We recommend that you call your local public health unit and ask to speak to a public health nurse who will be able to do a further assessment. You can find the number here.
