SHANGHAI (Reuters) – A Chinese drug company produced nearly 500,000 substandard vaccines for babies, roughly double an earlier estimate by authorities investigating a safety scandal, state news agency Xinhua reported on Wednesday.
China’s drug regulator in July accused Changsheng Bio-technology Co Ltd of selling 252,600 doses of ineffective DPT vaccines to inoculate children against diphtheria, whooping cough and tetanus.
