[Local reaction and neutralization test in smallpox vaccination after previous inoculation with MVA. Stickl's...

Of 200 first inoculations and 8 revaccinations, the sera were examined for content of neutralizing vaccine antibodies 3 weeks after the MVA graduated inoculation. In spite of imponderables which affect the failure rate in the "clinical trial", a positive result was obtained on first vaccination in 85%. In vaccinated children with a negative neutralization test a distinct booster effect was obtained with a "main vaccination" after about six months. The same effect was seen with revaccinations. For the time being inadequately controlled cerebral convulsive diseases, severe endogenous eczema, neurodermatitis, acute allergies, malignancies, immunosuppressive therapy, cortisole and intensive antirheumatic therapy and acute and purulent diseases must be considered as contraindications.
