On the morning of August 27, market news said that private medical institutions such as United Family Healthcare and Jiahui Health have suspended the vaccination of Sanofi's Pasteur influenza vaccine, involving trivalent and quadrivalent vaccines.

On August 27, Sanofi responded that influenza vaccine products are highly complex. During the ongoing stability study, SanofiThe potency of the influenza vaccines Valeline and Valeja (reference data for the expected biological effect of the vaccine) for the 2024-2025 influenza season has been observed to be on a downward trend. We expect that the efficacy of the vaccine may be affected before the end of the product's shelf life.As a precautionary measure, Sanofi has decided to temporarily suspend the supply and sales of these vaccines in China.

Sanofi said that the influenza vaccines Valeline and Valeja, which have been launched and circulated this year, have been approved for marketing, strictly abide by various laws and regulations, national drug standards and various statutory requirements, and meet the release standards. No signs or evidence of product safety and effectiveness being affected were found.The decision to temporarily suspend the supply and sale of these vaccines in China is merely a precautionary measure.

Sanofi emphasized that it is committed to maintaining the highest product quality standards and being highly responsible to its partners and the public. "We will continue to contribute to China's influenza prevention and control. For nearly 30 years, our influenza vaccines have protected thousands of Chinese families. We will continue to work with our partners to protect the health of more Chinese people."

Data from the China National Institute for Food and Drug Control showed that from August 5 to August 18, a total of 10 batches of influenza vaccines from Sanofi were approved for issuance.

The full name of influenza is influenza, which is a respiratory infectious disease caused by influenza virus that poses a serious threat to human health. Flu vaccination is an effective way to prevent influenza. Since influenza virus strains may mutate every year, flu vaccination is required every year.

In addition to Sanofi, domestic influenza vaccines include Beike Biotech (688276), Hualan Vaccine (301207), Sinovac Biotech, China Biologic Products, and Jindik (688670), etc. Influenced by the news that Sanofi stopped vaccination, Hualan Vaccine rose by 20%, Beike Biotech once rose by more than 4%, and Jindik once rose by more than 19%.

The reporter found in the United Family Healthcare mini program that Shanghai United Family Healthcare currently only offers appointments for Sinovac and Hualan influenza vaccines in its two branches, and no Sanofi Pasteur influenza vaccines (trade names: Valin and Valjia). Consumers who purchased Sanofi influenza vaccines at Jiahui Healthcare said they had received a notice from Jiahui Healthcare that the Pasteur influenza vaccine would be suspended from August 27. Another private medical institution, Yosemite, also said that they had received a notice that only Hualan Bio's influenza vaccine was available this year.

The reporter contacted a Shanghai community health service center posing as a parent of a child to be vaccinated. The staff said that there is no Sanofi influenza vaccine this year and the influenza vaccine has not arrived yet. Parents can pay attention to the relevant appointment platform to see which manufacturers are available and the products will be put on the shelves for everyone to choose.

Have other cities also been suspended? The United Family Healthcare mini program shows that nine hospitals in Beijing can register for influenza vaccine services, but does not show the specific vaccine brand.
