In the 2026 typhoid fever vaccine policy document, which replaced the 2018 document, WHO recommended that if children in very high-incidence areas receive their first dose of conjugate vaccine (TCV) at 9 to 24 months of age, a booster dose should be considered at about 5 years of age.<\/p>\n

This does not mean that every child in every country should be given a second dose. It is a conditional criterion for countries to jointly evaluate incidence, mortality, antibiotic resistance, decline in protective effect, cost and vaccination system.<\/p>\n

What’s new?<\/h2>\n

The 2018 standards emphasized one dose of TCV at least 6 months of age and a catch-up dose by 15 years of age if possible. The new document specifies for the first time criteria for judging booster vaccinations in specific high-risk situations, reflecting effectiveness and protection period data from actual introduction countries.<\/p>\n

Who should consider getting the vaccine at age 5?<\/h2>\n

In countries with very high rates of typhoid fever, children receiving their first TCV at 9 to 24 months of age are a key target group. We can also review where there is evidence of high incidence and reduced protection. If the first vaccination was given after the age of 2, additional vaccination may not be necessary even in medium- or high-incidence environments.<\/p>\n

How do I view vaccination intervals and records?<\/h2>\n

WHO said to try to leave at least a year between the first vaccination and the booster vaccination. They explain that booster vaccinations can be administered safely even if the exact date of the first vaccination is not known. The actual time and location will depend on the schedule of each country’s health authorities.<\/p>\n

Is the vaccine alone enough?<\/h2>\n

no. Typhoid fever spreads through contaminated food and water, so clean water, sanitation, hand washing, food safety and rapid diagnosis are all necessary. Although vaccines have become more important as the number of antibiotic-resistant bacteria increases, vaccines do not replace water and sanitation policies.<\/p>\n

What should individuals check?<\/h2>\n

This article is not a prescription for individual vaccinations, but rather an explanation of international policy changes. Recommendations vary depending on the risk of typhoid fever where you live or travel, your age, and previous vaccination history. You should check the WHO’s original text and the latest schedules of your country’s vaccination authorities and medical staff.<\/p>\n
