As in many other countries, almost none of the Cameroonian population are vaccinated against typhoid. Three different vaccines are available for use against S. Typhi infection: live attentuated Ty21a, unconjugated Vi polysaccharide ViPS and typhoid conjugated vaccine. The conjugated vaccine was pre-qualified via the World Health Organization (WHO) in January 2018 and is currently in trials. There is currently no available licensed vaccine for S. Paratyphi \cite{who2019}.  Diagnostics are important
