DEF

Réponse immunitaire (cellulaire ou humorale) qui suit la première rencontre avec un antigène

CONT

On oppose les réactions primaires observées après la première injection d'un antigène aux réactions secondaires qui se développent après une injection de rappel. On distingue trois phases au cours d'une réaction primaire : une phase de latence entre l'administration de l'antigène et l'apparition de taux détectables d'anticorps dans le sérum, une phase de croissance des titres d'anticorps, puis une phase de décroissance.
