TCV vaccination rates among cases and controls, and modeled estimates of vaccine effectiveness by vaccinated definition and age

Vaccinated Definition or Age	Typhoid Cases	No. of Typhoid Cases Vaccinated (%)	Matched Controls	No. of Typhoid Controls Vaccinated (%)	Modeled Vaccine Effectiveness (95% CI)
TCV card or campaign recall	35	3 (8.6)	140	53 (38.0)	83.7% (45.0–95.3)
TCV card or recall at any time	34	7 (20.0)	136	58 (43.0)	62.8% (10.7–84.5)
Age <5 years	8	1 (12.5)	33	11 (33.0)	72.3% (–144.0 to 96.9)
Age 5–14 years	27	2 (7.4)	107	42 (39.0)	87.0% (42.9–97.1)

TCV = typhoid conjugate vaccine.
