Protection in usually for life if one survives the disease. Protection is long lived, though not as long as natural immunization. Live pathogen Least safe. Mimic natural infection. Very dangerous with virus.
All antigens are intact and structurally sound.
Many antibody types formed. Attenuated pathogen Some risk, but dangerous with virus. Moderate to high immune system response. Killed pathogen Safe in theory, but some pathogen in the vaccine might not be killed. Some, but process used to kill pathogen destroys structure of many antigens.
