A bite by a copperhead (agkistrodon contortrix) rarely requires any intervention other than observation. The unnecessary use of antivenom should be avoided. Copperhead venom is a potent neurotoxin and should not be administered to a child under the age of 6 months. (CDC) recommends that all children 6 years of age and older be vaccinated against rabies.
Children who are not vaccinated are at increased risk for exposure to venomous snakes, including copperheads. In addition, children who have not been vaccinated may be at greater risk of being bitten by an animal that has been rabid.

In this study, we evaluated the efficacy and safety of a single-dose, oral, intravenous, and subcutaneous (scalpel-like) infusions of copper-containing encephalitis vaccine in a multicenter, randomized, double-blind, placebo-controlled, parallel-group study.
The primary outcome measure was the number of patients with a confirmed, clinically significant (≥1-day) copper encephalocele. Secondary outcomes included the incidence of adverse events (AEs) and the rate of serious AEs (SAEs). The study was approved by the Institutional Review Board of the University of Texas Health Science Center at San Antonio and was registered at ClinicalTrials.gov, number NCT01054127.
