My daughter went for her 14weeks immunization and nurse advised that it would give her diarrhea or constipation. she has had diarrhea for a week now. should we be worried?

Diarrhea ?'s: Diarrhea which is persistent should be checked by a physician. Some forms of acquired diarrhea are caused by bacteria and also parasites, and w/o treatment, your symptoms will persist.

Doctor can evaluate: There is no routine children's vaccination that a nurse or doctor should describe as "will give you diarrhea or constipation." The most common reason for diarrhea or constipation after a vaccination is just luck, either bad or good, meaning symptoms are coincidental. Theoretically, oral rotavirus vaccine can cause temporary stool pattern changes, but my patients have not reported that to me.
