Typhoid fever is a disease caused by Salmonella Typhimurium, usually infected by contaminated water sources, and is common in South Asia and sub-Saharan Africa, where sanitation is inadequate. Symptoms of typhoid fever include fever, headache, nausea, loss of appetite, constipation, and sometimes diarrhea. About one in 100 cases of infection died. According to the World Health Organization, about 21 million people are infected with typhoid fever each year, and about 222,000 of them have died.
According to French media reports on September 29, the researchers said on the 29th that a trial vaccine against typhoid can be safely used in the human body.
On the 29th, researchers published an article in the medical journal Lancet that the vaccine is aimed at young children under the age of 2 who are most susceptible to typhoid fever and is expected to avoid more than half of cases of typhoid infection.
The trial vaccine, called Vi-TT, has been licensed in India for use in babies, but has not been approved for use elsewhere, and there are no other vaccines for young children under 2 years of age.
The vaccine was tested on adult volunteers in the UK who were injected with a dose of Salmonella typhimurium and those who developed the disease were treated with antibiotics. The research team found that people who received this trial vaccine had less severe symptoms and fewer bacteria in the blood. The researchers compared the vaccination with other vaccines rather than the Vi-TT population and reached this conclusion.
The report said that the trial plan was by Bill and Melinda? Funded by the Bill and Melinda Gates Foundation and the European Commission, will continue to be implemented.
