Bad doses of baby vaccine are recalled

Two companies released thousands of ineffective inoculations for newborns

More than 650,000 doses of a vaccine routinely given to newborns in China have been recalled after testing showed they were ineffective.

The problem with the vaccine, which immunizes against diphtheria, pertussis (whooping cough) and tetanus, was identified after batches were distributed in Shandong and Hebei provinces and in Chongqing.
