Pakistan began vaccinating millions of children against typhoid on Friday to try to control a drug-resistant superbug outbreak of the fever that has already infected some 11,000 people since 2016 and risks spreading internationally.
The immunisation campaign, using a newly-developed shot designed to prevent typhoid fever infection for up to five years, starts in the southern Sindh province and is targeted at children between 9 months and 15 years old, officials said.
By 2021, it will become a nationwide programme and part of routine child vaccination schedules.
“Beginning the vaccination in urban areas is critical in preventing the disease among the communities most at risk,” Azra Fazal Pechuho, Sindh’s provincial minister for health, said in a statement. Typhoid also disproportionately affects children.
Typhoid is caused by Salmonella Typhi bacteria and spreads through contaminated food and water. It causes fever, nausea, stomach pain and pink spots on the chest, and in severe cases can lead to complications in the gut and head that can be fatal.
A Global Burden of Disease study by the U.S. Institute for Health Metrics and Evaluation estimates that in 2017 there were 11 million typhoid cases and 116,000 typhoid deaths worldwide.
