Whereas some protist species are essential components of the food chain and generators of biomass, others function in the decomposition of organic materials. Still other protists are dangerous human pathogens or causative agents of devastating plant diseases.

In about 30 percent of cases, however, the trypanosome causes further damage, especially to the heart and digestive system tissues in the chronic phase of infection, leading to malnutrition and heart failure due to abnormal heart rhythms.

Innate immunity, found in all metazoans, provides immediate, non-specific defense through germline-encoded receptors, while adaptive immunity, unique to vertebrates, involves specific responses with memory. It highlights immune cells, pattern recognition receptors (PRRs), and the role of adjuvants in enhancing vaccine responses.

It details various vaccine types and their roles against diseases like diphtheria, polio, and hepatitis, highlighting success in eradicating smallpox. The text notes ongoing challenges against polio and viruses like HIV-1, while introducing the potential of DNA vaccines that can elicit robust immune responses.
