[Concurrent] Mi Feng, Spokesperson of the National Health Commission
As of 24:00 on March 27, a total of more than 100 million doses of new crown virus vaccine have been reported across the country.
[Subtitle] On March 28, the Joint Prevention and Control Mechanism of the State Council held a press conference to introduce the situation of new crown vaccination.
At the meeting, a concentrated response was made to recent hot issues.
[Subtitle] How long is the protection period of the new crown vaccine?
Do I need a second vaccination?
[Concurrent] Wang Huaqing, Chief Expert of Immunization Program, China Center for Disease Control and Prevention
At present, the antibody level is monitored for more than six months.
But antibodies are not the only indicator of protection. There are other factors that play a role in the process of vaccines. Therefore, follow-up studies on the durable protection of vaccines are needed to determine how long the protection period is.
[Concurrent] Zhang Yuntao, Vice President of Sinopharm Group China Biology
In the clinical process of our overall design, a booster vaccination was designed. According to the preliminary results obtained, the booster can effectively increase the titer of neutralizing antibody, effectively improve the durability of the antibody, and also effectively improve the vaccine's anti-mutation ability.
In the future, for this vaccine, we will carry out Phase III clinical studies overseas to continuously observe the persistence of antibodies and protection. Does it need to be boosted?
When will you come to fight?
We still have to answer based on the results of the next three phases of clinical research.
[Subtitle] What should I do if I miss the second stitch?
Can it be inoculated from another place?
[Concurrent] Wang Huaqing, Chief Expert of Immunization Program, China Center for Disease Control and Prevention
If the first shot is inoculated and the second shot is not completed within the prescribed time, there is no need to restart the vaccination when the second shot is replanted, as long as the second shot is completed.
Of course, I want to remind everyone that when the second dose is inoculated, although the prescribed interval is exceeded, I also hope to get inoculated as soon as possible.
Regarding some personnel going to different places, it is mainly recommended to use the same company's varieties to complete two doses of inoculation. If the same variety is not available in different places, you can replace them with the same type of vaccine product to complete two doses of inoculation.
[Subtitle] Do newborns need to be vaccinated against the new crown?
[Concurrent] Wang Huaqing, Chief Expert of Immunization Program, China Center for Disease Control and Prevention
The current immunization strategy of our country is mainly for people aged 18-59 and those aged 60 and above who are in need and in good health.
Regarding the population under the age of 18, there is no systematic phase III clinical protection and safety data.
These data will be obtained in the future as the research progresses.
So when will vaccination be carried out for people under the age of 18?
From the perspective of the country as a whole, there are considerations. Based on the needs of epidemic prevention and control and the continuous improvement of clinical data, when and how to vaccinate people under the age of 18, this also includes the newborn population.
【Subtitle】Is getting the new crown vaccine necessary?
[Concurrent] Wang Huaqing, Chief Expert of Immunization Program, China Center for Disease Control and Prevention
Vaccination is the most effective prevention and control measure.
The more people who are vaccinated, the stronger the immune barrier is established, and the faster the inoculation, the earlier the immune barrier will be formed.
If there is such a mentality to not vaccinate, the immune barrier will not be established.
Anyone eligible for vaccination should be vaccinated.
I hope that through the joint efforts of everyone, the immune barrier will be established as soon as possible and return to the normal life in the past.
[Subtitle] Does the mutation of the new coronavirus abroad affect the effectiveness of China's vaccine?
[Concurrent] Zhang Yuntao, Vice President of Sinopharm Group China Biology
The two inactivated vaccines of Sinopharm Group, China Biologics, use serums from domestic and overseas Phase II and Phase III clinical trials, including strains found in South Africa and the United Kingdom, as well as 10 strains found in different regions and endemic areas in China. A cross-comprehensive experiment was carried out on multiple strains, and the results showed that the neutralizing antibodies produced by our two inactivated vaccines have a good neutralizing effect on these strains.
Sinopharm China Bio-New Coronary Inactivated Vaccine has been used in 50 countries and regions around the world as of today. The population sample size and the wide range of regions fully demonstrate the broad-spectrum effect of the New Coronary Inactivated Vaccine.
This is the situation where our seedlings are planted all over the world.
