Scientists have developed a new vaccine for typhoid that working very effectively against the disease. It is being used to stop or inhibit an untreatable strain of the infection according to doctors.
In the trails that have been conducted so far, the cases of the disease have fallen more than 80%. The details of the trials conducted have been published in the New England Journal of Medicine. Experts say that the development of this vaccine could play a potentially crucial role in stopping the bacterial disease.
In Pakistan, more than 9 Million children are being vaccinated. Typhoid has grown resistant to antibiotics. The bacteria known as Salmonella Typhi are responsible for the disease which is mostly found in children and spreads through contaminated food and water. In almost one in a hundred people suffer from fatal side effects such as internal bleeding.
The exact numbers of victims are hard to collect but according to data collected it affects somewhere between 11 and 21 Million people worldwide each year. Out of these 128,000 to 161,000 die due to the disease.
The trial was conducted in the Kathmandu valley in Nepal where 20,000 children who were suffering from Typhoid had been chosen to take part. This area was particularly chosen since the children in the area are particularly vulnerable to the disease. All the children were aged between 9 Months and 16 Years. Half of the children were given the vaccine and the cases of typhoid fell by 81% in the first year.
As mostly the children of poor families who do not get access to clean drinking water and food are affected by the disease, the poor families face a lot of burdens economically to pay the huge costs involved with the treatment. These children will be monitored in the due course of time to see how long the vaccine can protect the children against the disease.
