Available Typhoid Vaccines

1. Polysaccharide Vaccine (ViPS)

• Single injection
• Protection: ~3 years

• Lower cost

2. Conjugate Vaccine (TCV)

• Chemically linked polysaccharide to protein carrier
• More effective, longer-lasting protection

Key Points

• Both are safe and effective.
• TCV is now WHO-preferred for endemic areas and pediatric use.
