This afternoon (May 20), the Joint Prevention and Control Mechanism of the State Council held a press conference to introduce the situation of epidemic prevention and control and vaccination, and answer questions from the media.

In the past eight days, more than 100 million doses of the new coronavirus vaccine have been administered across the country. Mi Feng, spokesperson of the National Health Commission, said that recently, people across the country have been enthusiastically vaccinated against the new coronavirus. As of May 19, a total of 44,951.1 vaccinations have been reported across the country. million doses, of which more than 100 million doses were administered in the past 8 days.

A total of 21 new local confirmed cases have been reported in this round of clustered epidemics. Again, we remind you that prevention and control measures must be tightened at all times, and prevention and control measures must be implemented in detail. We must effectively achieve "early detection, early reporting, and early detection". "Isolation, early treatment"; it is necessary to consolidate the responsibilities of the four parties of the jurisdiction, departments, units, and individuals, and implement the requirements for traceability, isolation management, nucleic acid screening, and medical treatment in place.

Mixed administration of vaccines of the same type and the same technical route does not affect safety

Researcher at the China Centers for Disease Control and Prevention and member of the expert group for vaccine research and development of the Scientific Research Group Shao Yiming introduced that mixed administration of vaccines generally occurs among vaccines of the same type and the same technical route. Vaccine room. In this case, using a vaccine with the same technical route from another manufacturer will have exactly the same effect, and will neither affect the protective effect nor the safety of the vaccine.

Wang Huaqing, chief expert of the immunization program at the Chinese Center for Disease Control and Prevention, said that according to the technical guidelines for new coronavirus vaccination, it is recommended in principle to use products of the same technical route from the same company to complete the two-dose or three-dose vaccination program.

Inactivated vaccine There is no need to re-vacculate the second dose after 8 weeks

The best interval between the two doses of the new coronavirus inactivated vaccine is within 8 weeks. If the second dose exceeds 8 weeks, will it have no effect? At the meeting, Wang Huaqing said that under normal circumstances, vaccinations should be completed at scheduled intervals. If this interval is exceeded or lengthened further, subsequent vaccinations will also be effective.

He further reminded the public that when vaccinated, they should try to complete the second dose of inactivated vaccine within 8 weeks as required.

Wu Zunyou made an important judgment on the epidemic situation in Anhui and Liaoning.

In response to the current cluster of epidemics in Anhui and Liaoning, Wu Zunyou, chief expert in epidemiology at the Chinese Center for Disease Control and Prevention, epidemiology , said that there have been no locally transmitted cases in my country recently. This time In the case of cluster epidemics, the virus must come from people or items infected overseas, and traceability work is ongoing. The gene sequences of the cases in Anhui and Liaoning are exactly the same as , and they are on the same chain of transmission.

He said that at the social level asymptomatic infections will not exist for a long time. Generally speaking, asymptomatic infections are less contagious and long-term contact can cause transmission.

my country's existing vaccines can deal with the mutant strain found in India

Shao Yiming said that preliminary research results show that my country's existing vaccines can deal with the mutant strain found in India and can produce a certain protective effect. As the virus continues to mutate, the mutation will increase. Once there is a mutant strain that our existing vaccines cannot deal with, my country's inactivated vaccine has a quick way to deal with it.
