Typhoid fever surveillance study in sub-Saharan Africa shows need for typhoid conjugate vaccines in endemic countries

There is a high burden of typhoid fever in sub-Saharan African countries, according to a new study published in The Lancet Global Health. This high burden combined with the threat of typhoid strains resistant to antibiotic treatment calls for stronger prevention strategies, including the use and implementation of typhoid conjugate vaccines (TCVs) in endemic settings along with improvements in access to safe water, sanitation, and hygiene.
