A prospective participant was not be included in the study until the condition had resolved or the febrile event had subsided.~* History of convulsions.~* Any condition that in the opinion of the Investigator could interfere with the evaluation of the vaccine.~The above information was not intended to contain all considerations relevant to a participant's potential participation in a clinical trial.
