Overview

Shigella is a gram-negative pathogenic enterobacteria that causes severe diarrhea and dysentery in humans. Symptoms associated with Shigella infection includes fever, stomach pain, tenesmus, watery diarrhea, vomiting, dehydration, and convulsions. Various strains of Shigella are encompassed, such as S. dysenteriae, S. flexneri, S. sonnei and S. boydii. Each species of Shigella has different serotypes classified on the basis of the structure of O-antigens repeats that are the polysaccharides moiety of the lipopolysaccharide, a virulence factor consist of toxic lipid.

According to World Health Organization (WHO), nearly one million people die from Shigella infection annually. Moreover, the high incidence rate is seen among children less than five years age, travelers, and military personnel from industrialized economies. Shigella species have been identified from centuries and it represents a major threat to public health, due to non-availability of licensed vaccine and thus affecting overall Shigella vaccines market.

Historical Development

• According to the Centers for Disease Control and Prevention (CDC), in 2013, the average annual incidence of shigellosis in the U.S. was around 5 cases per 100,000 individuals. Bacillary dysentery with brutal epidemics was caused by S. dysenteriae by the production of shiga toxins whereas, the endemic form of disease was caused by the S. flexneri and S. sonnei. The bacillary dysentery was accompanied with fever, rectal inflammation, and abdominal cramps.

• For instance, in October 2019, The European Vaccine Initiative (EVI) and Hilleman Laboratories, announced partnership for the development of new shigella vaccine. Moreover, the EVI received a grant of US$ 9.5 Mn from the European and Developing Countries Clinical Trials Partnership (EDCTP) which aimed at developing safe and effective shigella vaccine.

• Also, in March 2017, Hilleman Laboratories, a non-profit organization established with joint venture partnership between Merck & Co., and Wellcome Trust, entered into an agreement with National Institute of Cholera and Enteric Disease (NICED) for the development and commercialization of vaccines against Shigella by 2025. Besides, in June 2016, Immuron—an Australian biopharmaceutical company—entered into an agreement to produce Shigella vaccine with the U.S. Army’s biomedical research lab—Walter Reed Army Institute of Research (WRAIR).

• Prokarium and Probiomed in January 2017, collaborated to manufacture orally-administrated vaccine to prevent diarrhea. The new vaccine was expected to be manufactured as a part of two-year collaboration having thermostable capabilities for a longer period. The new vaccine was expected to be delivered to the people living in the remote areas. Thermostable vaccine, which was manufactured at approximately one third of the price of the conventional injectable vaccines, helped to facilitate the growth of the Shigella vaccines market.
