A. There are antigens from the first exposure present
B. Over time pathogens usually mutate into less virulent strains
C. There are plenty of antibodies from the first exposure present
D. After the first exposure the immune system is capable of converting the pathogen into a non-virulent strain

Essay: Name TWO of the consequences of the formation of anti-body-antigen complex, for each outline the path of one of the outcomes of the immu…not have to contain all the steps in the process map)
-Elimination of intracellular virus
-Elimination of extracellular virus
-Immunologic memory
-Ineffective virus (not able to infect host cells)
- Neutralization: Binding antibodies to bacteria and viruses has protective effects. It prevents interactions of microbial agents limiting their effectiveness of spreading to other toxins.
- Opsinization: Tags foreign antigens for elimination via phagocytosis
