Vaccines involved in recent online reports about suspected inoculations of expired vaccines into children in Shangluo City in northwest China's Shaanxi Province have proved to be valid, said the National Health Commission (NHC) Thursday.
The online reports mainly involve five kinds of vaccines including those against DPT, ECM, and MMR, which were inoculated by three vaccination clinics in the city, according to the NHC.
On-site inspections showed all the vaccines were inoculated within the term of validity, the NHC said in a statement on its website.
The clinic staff, however, registered the vaccines with the wrong and expired batch numbers on the inoculation certificates, and failed to update related information in a timely manner and verify the numbers during the inoculations, leading to a mismatch, according to the statement.
The three vaccination clinics are understaffed, equipped with substandard facilities, and under lax supervision, it said
The investigation team has asked the local government to work out plans for rectification, conduct inspection and supervision on vaccination institutions, and fix loopholes in vaccine management.
