Long-Term Protection of Vi Antibodies Induced by Bio TCV in Indonesian Population Compared to PQed TCV
Sponsor: PT Bio Farma
Summary
Typhoid fever is a serious systemic infection caused by the enteric pathogen Salmonella enterica serovar typhi. S typhi is spread by the fecal-oral route. Although largely an endemic disease, S. typhi has epidemic potential. This research aims to determine the long-term immune response after administration of one dose of Bio TCV and PQed TCV vaccines in the population in Indonesia. Research participants will be taken from research participants who complete the Bio TCV (Typhoid 0319) Phase III clinical trial research included in the Main Study Group I.
