During a primary immune response, effector cells are the cells that act immediately to combat the pathogen. Neutrophils and eosinophils are part of the innate immune system and may also be involved in the primary response, but they are not specific to the pathogen like effector cells. Macrophages play a role in presenting the antigen to activate the adaptive immune response. Memory cells are formed during the primary response and do not act immediately.
