What it's about:
The GAVI global vaccine alliance has earmarked $85 million to help support the introduction of typhoid vaccines in poor countries where millions of children are at risk of the often deadly disease.
GAVI said it expects the first countries to apply for the vaccine next year, with the aim of starting to roll it out in 2019 for children over the age of six months.
GAVI, which is backed by the Bill & Melinda Gates Foundation, the World Health Organization, the World Bank, UNICEF, donor governments and others, funds bulk-buy vaccination programmes for poorer nations that can't afford shots at rich-world prices.
While typhoid is a bacterial disease that can be treated with antibiotics, access to antibiotics in poorer regions is sometimes limited, and the typhoid bug's resistance to them is on the rise.
GAVI Chief Executive Seth Berkley said the growing spread of drug-resistant strains of typhoid poses a major threat, to which a vaccine could offer an important defence.
Why it's noteworthy:
Typhoid is a serious fever caused by consuming contaminated food or water. It affects between 12 and 20 million people worldwide in regions where water quality and sanitation are low, particularly in South Asia and sub-Saharan Africa.
Around 1 in 100 cases is deadly, and about 3 percent of those infected become chronic carriers of the disease. Global health experts say typhoid killed more than 128,000 people in 2016.
