The World Health Organization (WHO) now recommends typhoid conjugate vaccines (TCVs) for integrated typhoid control programs. Countries should introduce TCVs to combat rising antimicrobial resistance and vaccine hesitancy.
Area of Science:
- Public Health
- Vaccinology
- Infectious Disease Control
Background:
- Typhoid fever remains a significant global health burden, exacerbated by increasing antimicrobial resistance.
- The development of a World Health Organization (WHO)-prequalified typhoid conjugate vaccine (TCV) marks a critical advancement.
- Existing typhoid control strategies require enhancement to address evolving challenges.
Purpose of the Study:
- To advocate for the timely introduction of TCVs into national immunization programs.
- To highlight the importance of integrating TCVs within comprehensive typhoid control strategies.
- To emphasize the need for strategic planning and community engagement for successful TCV deployment.
Main Methods:
- This is a policy and strategic recommendation, not a research study.
- Analysis of current global health landscape regarding typhoid fever.
- Review of recent advancements in vaccine technology and global health funding.
Main Results:
- A WHO-prequalified TCV is now available, supported by Gavi funding.
- WHO has issued a policy recommendation for the use of TCVs.
- Antimicrobial resistance is increasing the urgency for effective typhoid interventions.
Conclusions:
- Countries should prioritize the introduction of TCVs as part of integrated typhoid control programs.
- Continued vaccine development and ongoing studies are crucial for securing low-cost vaccines and optimizing deployment strategies.
- Effective communication and community engagement are essential to address vaccine hesitancy and ensure program success.

Development of Immunocompetence
The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.
