Immunization with the Chlamydia trachomatis major outer membrane protein, using adjuvants developed for human vaccines, can induce partial protection in a mouse model against a genital challenge. The observation that natural rotavirus infection, whether symptomatic or asymptomatic, provides partial protection from subsequent episodes of rotavirus gastroenteritis guided the development of the current generation of vaccines. There is thinning or loss of epithelium overlying the follicles, and they may become necrotic as the disease progresses. Because not all influenza-related deaths are manifested as pneumonia, the pneumonia and influenza mortality statistics probably underestimate the true impact of influenza on the population.
