An emergency vaccination campaign in Sindh following the outbreak of typhoid in the province has found the typhoid conjugate vaccine to be effective in preventing new cases of the disease, said researchers at an event at the Aga Khan University (AKU)
At the same time as the campaign, researchers set up a surveillance system in the same area over an 18-month period to screen a cohort of over 20,000 children, who received the vaccine, to detect cases of typhoid. They found that nine out of 10 children in the cohort, or 89 per cent, did not contract the disease
