The World Health Organization (WHO) has recommended the introduction of typhoid conjugate vaccine (TCV) for infants and children over six months of age in typhoid-endemic countries. The recommendation is based on a review of evidence on TCVs by WHO’s Strategic Advisory Group of Experts (SAGE) on Immunization in October 2017. The group considered data on vaccine safety, efficacy, feasibility, and affordability, as well as growing rates of drug-resistant typhoid. “Studies have shown that the typhoid conjugate vaccine is safe, effective, and can provide protection for infants and children under two years of age, unlike the previously available typhoid vaccines,” said Dr Adwoa Bentsi-Enchill, medical officer of the Department of Immunization, Vaccines and Biologicals at WHO. TCV provides longer-lasting protection, and requires fewer doses compared to earlier typhoid vaccines. It is suitable for children under two years of age. Vaccine introduction should be accompanied by catch-up vaccination campaigns for children up to 15 years of age in endemic countries, the position paper recommended
