At my child's Wellchild check up, he was accidentally given one of his brothers shots. It was harmless, but it might not have been. Is this a case?

I'm sorry to hear about this.  Thank goodness it was harmless.   And since it was harmless, and thus, there are no damages, you do not have grounds for a potential lawsuit.  You must have some sort of harm and resulting damages in order to proceed with a lawsuit.  However, you can look into filing a complaint with your state board of medical licensure if you feel that is an appropriate path to take.   For more information, visit:  http://www.dhp.virginia.gov/enforcement/complaints.htm NOTE:  This response is general in nature and should not be considered legal advice.  No attorney-client relationship exists or is formed by this response.
