Weegy: If a person has memory B cells against a certain pathogen,They are much less likely to develop the disease a second time if that pathogen infects the person's body again. ***Active immunity is immunity that results from a pathogen stimulating an [ immune response and leaving you with memory cells for the specific pathogen. This happens when a pathogen infects your body and makes you sick. As long as the memory cells survive, the pathogen will be unlikely to re-infect you and make you sick again. In the case of some pathogens, memory cells and active immunity last for the life of the individual. target=_blank rel='nofollow'>https://docs.google.com/viewer?a=v&q=cache:hyie5rIBX0cJ:' target=_blank rel='nofollow'>www.muhsd.k12.ca.us/cms/lib5/CA01001051/Centricity/Domain/812/CK-12/Immune_System_and_Disease.pdf+&hl=en&gl=ph&pid=bl&srcid=ADGEESiArwaAISDq9Chfd66Vm-E8CIF40GrKV7qJclXVL-80CM6ZFNyR8ks55WwmnohW0AZPfdy0Ag6GmTyuKU1NkIc1NLdvJLM-4YMpK- IyKKspHIv5KLzCAdakFV351Y_RX5w7q1f&sig=AHIEtbQwX4uAIlSiPYCnJ2oZzm6p9L2Tbw ] (More)
