The administration said on Tuesday that it has given local authorities until Friday to find out who bought the mishandled vaccines to ease public concern.
In addition, police in Shandong have detained 37 suspects implicated in the scandal, including a mother and daughter alleged to have illegally sold the improperly stored or expired vaccines, and people at three pharmaceutical companies, according to the work group handling the case.
Police in Hunan, Jiangxi and Guangdong provinces also have reported detaining suspects.
The Supreme People’s Procuratorate announced on Tuesday that it will directly oversee the case and urged prosecuting bodies at all levels to spare no effort in their investigations.
