Overview
Typhoid vaccine is recommended for travelers to areas where there is an increased risk of exposure to S.Typhi.
Indications for Use
The typhoid vaccines do not protect against S. Paratyphi infection. Both typhoid vaccines protect 50%–80% of recipients; travelers should be reminded that typhoid immunization is not 100% effective, and typhoid fever could still occur. Two typhoid vaccines are available in the United States:
- Oral live, attenuated vaccine.
- Vi capsular polysaccharide vaccine for intramuscular use.
