Abstract: Infectious agents contribute to the environmental factors involved in the development of autoimmune diseases possibly through molecular mimicry mechanisms. Hence, it is feasible that vaccinations may also contribute to the mosaic of autoimmunity. Evidence for the association of vaccinations and the development of these diseases is presented in this review. Infrequently reported post-vaccination autoimmune diseases include systemic lupus erythematosus, rheumatoid arthritis, inflammatory myopathies, multiple sclerosis, Guillain-Barré syndrome, and vasculitis. In addition, we will discuss macrophagic myofasciitis, aluminum containing vaccines, and the recent evidence for autoimmunity following human papilloma virus vaccine. ... Read more

Abstract: Despite their much-heralded clinical potential, therapeutic cancer vaccines have thus far failed to achieve the necessary clinical benchmarks to allow their regulatory approval. In contrast, vaccination against infectious pathogens represents one of the biggest achievements of modern medicine, and in certain cases such as vaccines against the human papilloma virus or hepatitis B virus, vaccination may impact the development of cancer. To the extent that these two approaches differ as immunotherapy vs. immunoprevention, the challenge is to rethink the types of non-viral antigens that are currently being targeted in cancer vaccines. Immunological analysis suggests that the telomerase reverse transcriptase hTERT is a widely applicable target recognized by T lymphocytes and a prototype for a novel class of universal tumor antigens. Findings from initial clinical trials demonstrate that hTERT-specific immune responses can be safely induced in cancer patients. If the amplitude and duration of cellular immunity against hTERT can be optimized without toxicity in humans, then an opportunity exists to test hTERT vaccination as a way to reduce the risk of cancer recurrence in patients or even the risk of developing cancer in otherwise healthy individuals. ...

Abstract: The clearly defined causation by papillomavirus (HPV) and precursor lesions of cervical cancer have made this cancer largely preventable through Pap screening programs, and now by vaccination with Gardasil. This represents an important public health success story and here the authors summarize the potential impact of preventive HPV vaccination and some of the outstanding questions. ... Read more
