New Typhoid Vaccine Recommended by WHO

24 Oct 2017

World Health Organization (WHO) recommended a new vaccine for typhoid fever for infants and children over 6 months in typhoid endemic region. This new vaccine was expected to have a huge impact on typhoid cases globally as it was said to prevent nine out of ten cases of typhoid¹. No currently available vaccines against typhoid are meant for children under the age of 2, which is particularly at higher risk of typhoid infection.

Importantly, this new vaccine may also be a valuable weapon in the fight against antimicrobial resistance. Cases of multi-drug resistant (MDR) typhoid are increasing at an alarming rate especially across Africa and Asia. Last July, MDR outbreak in Hyderabad, Pakistan had infected over 250 people with 75% of the cases were children under 10².

Inappropriate use of antibiotics due to lack of control and false diagnosis are believed to be the major cause of emergence of multi-drug resistant strains³. Thus, accurate diagnosis of typhoid fever at its early stage is crucial to curb this disease that has infected almost 22 million lives every year.
