On May 20, the Joint Prevention and Control Mechanism of the State Council held a press conference in Beijing. Responsible comrades from the National Health Commission’s Bureau of Disease Control and Prevention and the Guangdong Provincial Health and Health Commission, and experts from the Chinese Center for Disease Control and Prevention and vaccine research and development classes attended to introduce new coronavirus pneumonia. Epidemic prevention and control and vaccination related situations.

The pressure on China’s foreign defense imports continues to increase,

The string of prevention and control must be tightened at all times

In the past week, the epidemic situation in neighboring countries and regions is still showing an outbreak and spreading trend, and the pressure on China’s foreign defense imports continues to increase. A total of 21 new locally confirmed cases have been reported in this round of clustered epidemics. The Joint Prevention and Control Mechanism of the State Council has dispatched working groups and expert groups to guide epidemic management and medical treatment in Anhui and Liaoning. The recent epidemic reminds us once again that prevention and control measures must be tightened at all times, prevention and control measures must be implemented in detail, and "early detection, early reporting, early isolation, and early treatment" must be achieved, and jurisdictions, departments, and units must be consolidated , personal four-party responsibilities, and implement the requirements for traceability, isolation management, nucleic acid screening, medical treatment, etc.

Recently, people all over the country have been enthusiastically vaccinated against the new coronavirus. As of May 19, a total of 449.511 million doses have been reported nationwide, including more than 100 million doses in the past eight days.

Where did the virus in the cluster epidemics in Anhui and Liaoning come from?

There have been no locally transmitted cases in my country recently. In other words, the virus that caused the cluster epidemic must have come from people infected abroad or contaminated items. The traceability work is under investigation.

Judging from the genetic sequence of the virus, the cases in Anhui and Liaoning are exactly the same and should be part of the same chain of transmission. There will not be asymptomatic infections at the social level for a long time. Generally speaking, asymptomatic infected persons are less contagious and usually only infect people with whom they have frequent contact for a long time, such as people who live together or work together. Asymptomatic infections will not continue to spread to one or two generations. Even if they spread to one or two generations, if no clinical symptom cases are caused, it will be automatically terminated; if clinical cases appear, it may trigger a local epidemic.

Judging from the serological double antibody tests of the 10 cases reported in Anhui on May 14, the antibodies were all negative, which means that the infection was not long. Judging from the results of two rounds of screening in Anhui and Liaoning, the epidemic will not be as large as at the beginning of this year.

What is the current epidemic prevention and control situation in Anhui and Liaoning?

Recently, local clusters of epidemics have occurred in Liaoning, Anhui and other places. After the outbreak, the National Health Commission and the State Administration of Disease Control and Prevention quickly launched an emergency response and urgently dispatched two epidemic response standing working groups to the local area to guide prevention and control work. At present, various prevention and control work are being carried out in an effective and orderly manner. Both Liaoning and Anhui provinces have held multiple press conferences to inform the public about the latest epidemic situation and progress in prevention and control work.

Over the past year or so, my country's epidemic prevention and control situation has been generally stable. There have been no local epidemics in most areas across the country. Some places and people have become paralyzed and relaxed. This epidemic has once again sounded the alarm for us, reminding us that the epidemic is not over yet. International epidemics continue to occur at a high rate, and the risk of importation into our country increases. The epidemic prevention and control situation remains severe and complex, and the epidemic prevention and control work presents the characteristics of long-term, complex, and uncertain. , reminding that epidemic prevention and control work cannot be relaxed even for a moment.

We call on the whole society to further increase risk awareness, correctly understand the epidemic prevention and control situation, low domestic epidemic risk does not mean zero risk, jointly implement various measures for the prevention and control of the new coronavirus pneumonia epidemic, actively cooperate and participate in the new coronavirus vaccination work, and jointly protect the future. A hard-earned major strategic achievement in the fight against the epidemic.

Does "one bottle of vaccine for two people" affect the effectiveness?

The two-dose vaccines and one-dose vaccines produced by Chinese manufacturers are the same in terms of raw materials and excipients, production formulas, packaging materials, production sites and process parameters , the only difference is whether the filling amount is one dose or two doses.

Some members of the public may be worried that if one bottle is used for two people, the amount of vaccination for each person will not be enough. In fact, each bottle has a surplus capacity, which is enough for two people. In fact, the new coronavirus vaccines used internationally are basically packed for 5 or even 10 people.Its advantage is that it can transport more vaccines in the same time, save the amount of packaging materials, and improve transportation capabilities. This way, it can better provide large-scale vaccination for the whole country, and Chinese vaccines can be used by the world to play their role.

With the advancement of the vaccination plan, our country has already reviewed the vaccines in different doses in the early stage, and the review channels are completely smooth. If there is demand, we can quickly adjust other vaccines into multi-dose packaging to facilitate use in China and internationally.

Will the second dose of vaccine be ineffective if it is more than 8 weeks old?

There is a general principle when receiving the new coronavirus vaccine. That is, if the vaccine requires 2 or 3 doses, there is a gap between doses. Intervals, usually, are completed at program intervals. If this interval is exceeded or lengthened further, subsequent vaccinations will also be effective. For the new coronavirus inactivated vaccine, our requirement is to complete it within 8 weeks. If the interval between the second dose and the first dose exceeds 8 weeks, there is no need to re-vacculate or restart vaccination. Therefore, if it is more than 8 weeks, just make up the missing doses.

Of course, I would like to remind the public that when receiving the vaccine, they should try to complete the second dose of the inactivated vaccine within 8 weeks as required.

In terms of foreign import prevention, what experience can Guangdong draw from?

Guangdong is the province with the largest number of immigrants during the epidemic. Currently, Guangdong Province accounts for 90% of the country’s daily arrivals, and there are more than 300 centralized isolation points in use. There are nearly 30,000 people in quarantine every day and nearly 20,000 quarantine workers.

Based on the reality of prevention and control in Guangdong, in terms of imported foreign defense, the relevant departments of the Guangdong Provincial Joint Prevention and Control Mechanism have always adhered to the joint prevention of people and environments, the joint prevention and control of Guangdong, Hong Kong and Macao, and the "four stricts" to achieve closed-loop management and build a solid foundation from the country to the door. line of defense.

First, strictly implement the closed-loop management of overseas personnel coming to Guangdong. Build a solid "five lines of defense" of port quarantine, medical observation isolation points, community screening, fever clinics, and medical treatment, and strictly implement the "four full coverages" of health screening for entry personnel, nucleic acid testing , closed transfer, and isolation medical observation. Realize full-process closed-loop management from country to home. In addition, the "One Code" health service code is implemented to achieve "one declaration, multiple points of interconnection, and full sharing" for inbound passengers. For all overseas visitors to Guangdong, strict isolation and health management will be implemented in strict accordance with relevant national regulations.

The second is to strictly implement health management of key groups. For key groups and related personnel who have direct contact with overseas people and goods, such as port staff, transshipment personnel, and quarantine hotel staff, a health monitoring ledger will be established and included in the scope of "all inspections that should be carried out" for nucleic acid testing, and "should be carried out" for vaccination. The key groups of "pick up and pick up". Implement "one week of testing, two sets of clothes, three-area management".

Among the key groups in Guangdong Province, cross-border truck drivers are the focus and difficulty in preventing the cross-border import of overseas epidemics. They are strictly subject to entry quarantine, entry health declaration and " Guangdong Health Code " scanning code to pass. In addition, eight major measures have been implemented to strengthen the management of point-to-point transportation trajectories and supervise epidemic prevention across the entire cross-border transportation line, forming a "three-point and one-line" full-process closed-loop management of entry points, operating points, accommodation points, and work along the route.

The third is to strictly implement joint prevention and control between Guangdong, Hong Kong and Macao. Strengthen information sharing and emergency coordination, and strengthen the management of exempted personnel and mobile fishermen at sea. At present, Guangdong, Hong Kong and Macao have achieved "double mutual recognition" of nucleic acid test results; Guangdong and Macao's prevention and control measures have achieved three "integrations", and the two places can travel freely with a valid nucleic acid test certificate within 7 days.

The fourth is to strictly implement full coverage monitoring measures for imported goods such as cold chain food. Focusing on the three key points of "people, products, and environment", we will implement "three enhancements and three coverages", that is, continue to strengthen the weekly coverage of nucleic acid monitoring of direct contact personnel, products and environment in cold storage and cold chain logistics enterprises; continue to strengthen the implementation of daily cleaning of the market environment Ventilation and disinfection are fully covered; safety supervision of imported frozen meat products and aquatic products continues to be strengthened and fully covered.
