CCTV: As early as November, the domestic public can be vaccinated against the new crown

On September 15th, according to CCTV News 1-1, Bai Yansong connected wu Guizhen, chief expert in biosecurity at the China Center for Disease Control and Prevention, who disclosed the latest progress on whether autumn and winter may face a new coronal pneumonia outbreak and influenza overlay epidemic, how the flu vaccine should be played, and new crown vaccination.
progress of the new crown vaccine currently being developed in China? Wu Guizhen pointed out that China's vaccine research and development and production in the world's leading.
there are currently nine vaccines in Phase III clinical trials worldwide, and China accounts for five (a new crown vaccine for international cooperation between China and other countries, just entered), and progress is very fast.
The new coronavirus is a high-risk virus, need to be produced in the negative pressure workshop, it is understood that the country is currently being carefully organized by the Health and Safety Commission experts to review the production workshop, there have been two production workshops approved, is in the process of a third.
how long will it take for ordinary people to get the new crown vaccine? Wu Guizhen pointed out that about November or December, ordinary people can be vaccinated against the new crown vaccine, according to the third phase of clinical results, the current progress is very smooth.
the vaccine could produce up to a billion doses by 2021.
CCTV news report, in April this year, some of the experimental population was vaccinated, it is understood that the subjects these months feel very good, there is no different place, vaccination, local no pain, experience is very good.
the effectiveness of the vaccine expected to work after 1-3 years of new crown vaccine, has been a hot topic.
Wu Guizhen pointed out that because the occurrence of neo-crown pneumonia is not long, so the vaccine development time is not long.
based on past experience and the results of past studies, we expect it to be effective for about one to three years.
because of the short time, we are still watching.
" at present, the domestic vaccination of the new crown vaccine, mainly some people abroad.
this part of the people need to go abroad to work and study, this part accounted for a large proportion.
so far, they have worked very well and have not had any side effects.
" In addition, none of these people who were vaccinated were infected with neo-coronary pneumonia, which is the result of current observations.
Because the early symptoms of neo-crown pneumonia are similar to influenza, wu Guizhen pointed out that autumn and winter are prone to high incidence of respiratory infections, such as influenza, pneumonia and other infectious diseases, and low temperature for the new coronavirus is easy to spread.
the early symptoms of the new crown will be similar to the flu, one is the season, coupled with their similar symptoms, so the public is called upon to be able to get the flu vaccine, but also to prevent the occurrence of infection, clinical identification difficulties.
is it important to encourage more people to get the flu vaccine? Wu Guizhen pointed out that some groups of people can give priority to vaccination, such as patients with chronic diseases or the elderly, children.
the vaccination rate of our influenza vaccine in previous years is very low, less than 2%, in Western countries, some countries the vaccination rate of the elderly reached 50%, the vaccine is still very effective and beneficial to prevent influenza.
Wu Guizhen stressed that the influenza vaccine and the new crown vaccine does not conflict, can be vaccinated in a se as a result, influenza vaccine and new crown vaccine prevention is completely two diseases.
Mass production of vaccines will not take place until early August, according to China Biometrics, the Beijing Institute of Biological Products, the new crown inactivated vaccine production workshop has passed the joint inspection of biosecurity organized by the relevant state departments, with the conditions for use.
, the production facility has just obtained a new crown vaccine production license.
beijing's high-grade biosecurity facility, which has passed inspections, is the world's first and largest production plant for new crown inactivated vaccines.
beijing Institute of Biological Products in just 2 months, on April 15 completed the construction of the workshop, creating a new crown inactivated vaccine workshop construction of the "Fire Mountain" speed.
mid-July, experts from relevant state departments conducted a comprehensive inspection of the biosecurity of the new crown vaccine production workshop of the Beijing Institute of Biological Products, which was considered to meet the requirements of the relevant national standards and could be put into large-scale production of the new crown vaccine.
China's Vaccine Management Law stipulates that when a particularly major public health event occurs, the vaccine may be used urgently within a certain range and within a certain time frame, with the aim of establishing an immune barrier in a special population such as medical personnel, epidemic prevention personnel, border control personnel and those who guarantee the basic operation of the city.
In response to the many problems of the new crown vaccine, Wu Zunyou, chief epidemiologist at the China Center for Disease Control and Prevention, said that human infection with different viruses produces immunity persistence is not the same, some will have life-long protective effects, some produce very limited immunity.
"There are no definitive results for the immunity of new coronavirus, but observation of immunity to other coronavirus viruses can generally be maintained for 6 to 12 months."
as long as the vaccine is protective, it is very important that it can effectively control the outbreak and bring down the peak of the epidemic, " he said.
with the new crown vaccine, it is possible to suppress peaks and keep the number of cases under control, which is particularly helpful for controlling the outbreak.
