Venom immunization: IgG/IgE titers, safety, risk, and methods of the VIPRBITEM cohort

Immunization of humans to snakebite is effective, and reasonably safe with care. Injection records suggest immune cross-reactivity between ophidians within the same family, and better cross-reactivity within the same genera. A cohort participant was pronounced dead based on EEG, and then recovered without treatment. A neurotoxin case with "brain death" EEG should stay on life support for 6 weeks to allow time for the immune system to clear venom.
