Provide two examples of how the immune response to bacterial antigens or toxins can cause severe disease and pathology. For each example, name the disease, the bacterial species, the corresponding bacterial toxin or antigen associated with the disease, and the immune response driving the pathology.
Vaccines have been shown to NOT cause autism, but still controversies persist because of a lack of understanding about how vaccines work and how they are made. A vaccine is a biological preparation that improves immunity to a particular disease. A vaccine typically contains an agent that resembles a disease-causing microorganism and is often made from weakened or killed forms...
