See the DrugPatentWatch profile for Typhoid
The main typhoid vaccines are typically referred to by these names: - Typhoid conjugate vaccine (TCV) (common brand names vary by country) - Typhoid polysaccharide vaccine (ViPS or Vi polysaccharide) (often referred to simply as the typhoid Vi vaccine)
Most modern immunization programs and travel clinics refer to TCV when they say “typhoid shot,” because it’s a conjugate vaccine rather than the older polysaccharide type.
Brand names differ by country and procurement program, so the exact name can change. If you tell me your country (or the vaccine brand you were given), I can help identify whether it’s TCV or Vi polysaccharide.
