A new vaccine that could prevent up to nine-in-10 cases of typhoid fever has been recommended by the World Health Organization.

According to the BBC news, experts say it could have a “huge impact” on the 22 million cases, and 220,000 deaths, from typhoid each year.

Crucially it works in children, who are at high-risk of the infection, unlike other typhoid vaccines.

It is hoped the vaccine could eventually help countries eliminate typhoid.

Typhoid fever is caused by Salmonella Typhi bacteria and patients have: prolonged fever, headache, nausea, loss of appetite, constipation and in one-in-100 cases it causes fatal complications.

The bacteria are highly contagious and spread through contaminated food
or water.

The infection is most common in countries with poor sanitation and a lack of clean water, particularly in south Asia and sub-Saharan Africa.

Two typhoid vaccines already approved to help reduce the number of cases, but none are licensed for children under the age of two.
