With an investment of S$510 million, our state-of-the-art vaccines manufacturing facility at Tuas was opened in June 2009 by Singapore's Prime Minister Lee Hsien Loong, coinciding with our 50th anniversary in Singapore. Comprising two production buildings, an administration block, quality control laboratories, utility plant and warehousing, the facility became operational in 2011. The facility and operations meet the high quality and good manufacturing standards of global regulatory bodies such as the European Medicines Agency and the United States Food and Drug Administration. 

Tuas is a key manufacturing site within our network supplying the active ingredient used to make our pneumococcal conjugate vaccine. This paediatric vaccine is indicated for the active immunisation against pneumonia, invasive diseases and acute otitis media caused by Streptococcus pneumoniae in infants and children.

Hib is a bacterium responsible for invasive diseases, such as severe pneumonia and meningitis, contracted almost exclusively by children less than five years old. 

These two vaccine products manufactured at Tuas cover a number of diseases causing paediatric mortality in the world, making a significant contribution to our global health agenda.
