It was officially opened on 26 October 1913 in the Luang Building on Bamrung Muang Road as the Pastura Institute after Louis Pasteur, who discovered the first vaccine against rabies. In 1917 it was renamed the Pasteur Institute and placed under the supervision of the Thai Red Cross Society. The institute also produced vaccine against smallpox. The Travel and Immunization Clinic is now located here. If offers vaccines and pre-travel consultation.In the early-1920s the king offered his private property for the construction of a new home for the institute on Rama IV Road. The new buildings were officially opened on 7 December 1922, now named for the king's mother, Queen Saovabha Phongsri. At the same time, the institute's first director, Dr. Leopold Robert, requested contributions from foreigners living in Thailand for the establishment of a snake farm, which would enable the institute to manufacture antivenom for snake bites. Reportedly the second snake farm in the world after Instituto Butantan in São Paulo, Brazil, it was opened on 22 November 1923 by Queen Savang Vadhana, then President of the Thai Red Cross, on the institute's premises.Research into snake venom is highly important, since many people fall victim to venomous snake bites.

The snake farm houses thousands of some of the most venomous snakes in the world, such as the king cobra and all sorts of vipers.
