After the news of the falsified Changchun Changsheng vaccine was exposed, many netizens who had received rabies vaccine expressed concern online, unsure if the product they received was from Changchun Changsheng. Once the faulty vaccine made its way to the market, there would be people who had received this batch of vaccine. So, how do we determine if we have received the vaccine in question? How to confirm vaccination with the problematic vaccine The simplest and most direct way for people who have received rabies vaccine to inquire about the documents proving that the vaccine was approved by the batch is to go to the vaccination clinics (including rabies exposure disposal clinics); the same documents are available at the county-level disease prevention and control agencies that procure and distribute the vaccine. Since 2006, China has implemented batch issuance for all listed vaccines, which is a mandatory inspection and audit of each batch of vaccine when it leaves the factory for market or is imported. The focus of the data audit is on whether the production and quality control of each batch of vaccine is consistent with the state-approved processes and standards. The news is that the safety of the vaccines that have been marketed will not be a problem, and that the company’s problematic rabies vaccines have not been brought to market, but have been sealed in place, and the vaccines that have been sold and not yet used have been sealed and recalled, and there should be no rabies vaccines from the company on the market now. There are no reports that there are problems with the company’s other vaccines, at least not yet. Those who are receiving rabies vaccine from the company can switch to other companies, and those who have already received a course of vaccination do not need to be revaccinated until there is no official news. vaccine of uncertain potency was used, it is necessary to consider testing one’s antibody titer to determine whether a booster immunization is needed. For the safest consideration, we have to wait for further identification and sampling of retained products for laboratory evaluation results from relevant parties.
