There are calls within China for tough action to be taken after up to eight babies died following vaccination against hepatitis B. As investigations continue, authorities already suspended use of the vaccine at the center of the scandal produced by the Chinese drug manufacturer BioKangtai. Only a few areas bought this vaccine, says this official, seeking to reassure parents about the government’s immunization program. We’ve asked them to report the number of these vaccines used. We also monitor if they have a bad reaction. So far, there’s none. The firm says it’s testing the batches in question but insists it rigorously followed safety rules. After several scares, many Chinese people are suspicious that the government tries to cover up bad news about health problems, despite assurances of transparency.
