Volunteers describe: after two injections of domestic new crown vaccine is what kind of experience

Text . . Jianwen Mao Xiaoqiong's current domestic epidemic is stable, but autumn and winter is coming, the new crown virus's counter-attack is in sight.
experts Zeng Guang and Chen Weijun believe that this will be a difficult battle.
vaccine offers hope.
"Driving home suddenly a little dizzy, there is a feeling of drunk driving", September 2, cultural historians, time commentators ten years of wood-cutting described how he felt after the new crown vaccine.
more than 20,000 volunteers in China have been vaccinated against the new crown, and cutting wood in a decade is one of them.
, the first public appearance of the domestic new crown vaccine.
2020 China International Trade Fair on Services, held in Beijing from September 4th to 9th, two inactivated vaccines from China Biology and Koxing Bio, the Chinese pharmaceutical group, were on display at the same time.
, the number of newly diagnosed patients is close to 27 million and is still being added, and the ad-flux of vaccines means that hopes are fading.
we are now in a new round of fighting between the two armies, " he said.
the first round of China's outbreak zero, playing well, most countries are more difficult.
now that we have the vaccine, we're going to play the second round, and we have a chance to adjust before the vicious face of the virus is fully exposed.
" on the evening of September 2, and ten years of wood cutting at the same time to participate in the eight-point health news launched by the "healthy news link", the National Health and Wellness Commission high-level expert group members, china CDC pre-epidemiology chief scientist Zeng Guang so commented on the current situation of epidemic prevention and control.
Chen Weijun, chief scientist of Huada Gene Infectious Diseases, who also participated in the connection, shares Zeng Guang's view and believes that "we don't know how it (the new crown virus) will counterattack" and that the vaccine is a counter-attack weapon, revealing that China's new crown vaccine could be approved as soon as December, and that he believes "5-600 million doses is not a problem".
of the new crown vaccine has continued to rise since August.
Russia's attempt to later declare the world's first new crown vaccine registered without a Phase III clinical trial, would it be safe and effective? At the same time, the world's many vaccines into phase III clinical, should soon be able to have more reliable results.
, but at the same time, there have been secondary infections in Hong Kong, and the effectiveness of future vaccines has been called into question.
the core of our concerns is: Can vaccines help protect humans from the new coronavirus? Vaccination or have a slight reaction but should not overstate "I am willing to do mice, the biggest reason is to have confidence in our country's vaccine preparation technology, I think such a large state-owned enterprises as the national medicine, without full confidence, will not openly recruit volunteers."
, my job needs to travel a lot, and I think after the vaccine, at least the psychological pressure will be a little less.
" decade of cutting wood to share her experiences as a volunteer getting the new crown vaccine.
July, he was invited by a friend to volunteer with the National Pharmaceutical Group, and on July 22nd and August 24th he was vaccinated against the new corona inactivated vaccine developed by the National Pharmaceutical Group.
of all the different vaccine technology routes, inactivated vaccines are the most sophisticated and safe.
August 23, the State Council SASAC Information Center officials micro-showed that the State Pharmaceutical Group of China Bio-New Crown Inactivated Vaccine was officially launched on July 22 emergency use, the number of people in the group more than 20,000.
vaccine has not yet been approved for sale, why is it available for widespread vaccination? Chen Weijun, chief scientist for genetic infectious diseases at Huada, explained that China's Vaccine Management Law allows emergency vaccination of high-risk groups by any vaccine after the completion of Phase II clinical trials.
" includes front-line medical staff, staff who maintain basic urban operations, and foreign workers who are most at risk of exposure to the virus.
is also the elderly, because this new crown shows that the harm to the elderly is relatively large.
that passing Phase II clinical trials means that basic safety is guaranteed, and you can rest assured of that.
" and for everyone's most concerned about the vaccination experience, ten years of wood cutting in the program said, slightly uncomfortable, no major problem.
"the first shot I didn't feel anything, just a little nauseous, sitting in the vaccination room for half an hour.
when the second shot when the reaction is a little longer, in my drive home suddenly a little dizzy, there is a feeling of drunk driving, I purposely found a place to stop the car, a moment, just feel better.
" to this, some viewers said that they have also been vaccinated by the National Pharmaceutical Group, a week later developed symptoms of heart discomfort, some worry, to consult two experts.
Chen Weijun said that from a scientific point of view, today's technology and technology, vaccines can cause a very low chance of serious adverse reactions, many times there may be psychological sensory factors.
Zeng Guang expressed a similar view, in his view, after vaccination adverse reactions, can be divided into general adverse reactions and extreme adverse reactions.
"I don't think to exaggerate the general adverse reactions, such as needle eye pain, the general people have, in addition to thick skin people, the appearance of small redness and swelling ah, low heat ah, affect sleep ah ... On the other hand, I know that we have a lot of experts in the industry have been vaccinated themselves, some of them in the first phase of clinical trials, which shows that everyone is still confident about the safety of the vaccine.
"China's indisputable speed first effective is the key indicator since more than 20,000 people have been vaccinated, when will the new crown vaccine be fully rolled out?" This is another issue of concern to all.
Chen Weijun said that the current domestic vaccine research and development is in an orderly way, has entered the final phase of clinical trials before the market, this stage has a lot of work to do.
For example, for volunteers in Phase III clinical trials such as "Ten Years of Wood Cutting," vaccine developers need to test their antibodies, analyze differences between vaccinated and control populations based on epidemiological data, and ultimately give a comprehensive evaluation of vaccine effectiveness.
but not all countries follow this set of principles.
August 11, Russian President Vladimir Putin announced that Russia had successfully registered the world's first new crown vaccine, completing a corner oversized ride for China and the United States.
, but it is understood that the Russian vaccine has only passed Phase II clinical trials, the registration of the market is only an emergency.
Chen Weijun said that there is no need for mankind to compete with each other who first, security and effective is the first thing, after all, our common "enemy" is the virus.
" from the point of view of emergency prevention and control, some countries after the completion of the second phase of the claim that the listing is available, but how effective, whether to block the epidemic infection rate has a role, or to see the third phase of data.
we don't have to care who's the first, don't argue who's first, only scientifically protect everyone, is the first.
" Zeng Guang also said that Russia's approach is a bet, more political considerations, but in any case, sincere hope that Russia's vaccine will work.
"because if there is a problem in Russia, it will affect vaccines in other countries."
they do this, China will not follow suit, you do yours, we wish you good luck.
, I hope the United States will succeed soon, who first and then do not matter, the virus is our common enemy.
" Chen Weijun revealed that according to the current public progress, China's new crown vaccine may be approved for sale as soon as December this year.
" new crown vaccine to fight twice, some people said before the add up to more than 1000 yuan, I believe it can not be used, will certainly be much cheaper than this.
production, the production capacity of the National Pharmaceutical Group alone has 300 million doses, and then join our other companies, I think 5-600 million doses is not a problem, the domestic should be able to meet the supply, first of all, the need to vaccinate the high-risk groups hit, it will naturally form an immune barrier, and then gradually inoculated to the general population.
" secondary infection of less than 10 people vaccine is still the most effective weapon another topic of concern is that Hong Kong's secondary infection cases.
for vaccines, the principle is to emulate the process of producing antibodies in the infected body, activating the body's immune system.
if a new corona patient can be second-time infected, does that mean the antibody itself is ineffective? Chen Weijun gave positive opinions on the protective effect of the vaccine.
said that vaccines are a very effective public health tool, and we evaluate vaccines first from a public health perspective, from an epidemiological big data perspective.
today there are more than 20 million cases worldwide, the number of reported secondary infections is limited, from this point of view, it should be said that the infection is still protective.
addition, in fact, the reported cases of secondary infection in Hong Kong have repeatedly stressed that their pre-infection antibodies have not been detected, and secondary infection is mild.
From this information alone, from a good point of view, it is not antibodies that do not work, it is possible because the antibody property price is low (not detected), it is possible to secondary infection, so this may suggest from another side of the effectiveness of the vaccine.
, believes that secondary infections are present in Europe and the United States, but add up to less than 10.
compared with the global total of more than 25 million cases, the proportion is very small, to use the old saying is "the forest is big, what kind of birds will have."
" biomedical science, there is this law of large numbers.
for any species, exceptions arise as long as the number is large enough.
most typical of this is a human soy infant, which is essentially a biodiversity issue.
" at the same time, Zeng said, they are also looking at these secondary infection patients.
from an epidemiological point of view, they are more concerned about whether the virus in these patients is mutated, pathogenic and more pathogenic, but the conclusions do not support the above judgment.
, he would like to reassure you that these extreme cases will not affect the progress of vaccine research and development, nor will they change the prevention and control strategy of the outbreak, let us have an impact on our lives.
counter-offensive is coming Don't think you can kill it with a stick Although the current outbreak in the country is still stable, but autumn and winter is coming, the new crown virus counter-attack is in sight.
has just reminded everyone that this is going to be a tough fight.
" has such a rule, the better the prevention and control, the higher the proportion of susceptible people, such as in our country, the lowest proportion of susceptible people is more than 95%, Wuhan City.
this is a result, but also a risk, because more susceptible people, like dry firewood, to ignite a fire, the introduction of cases, there is a possibility of burning up.
" another noteworthy situation is that, according to WHO projections, this year's influenza virus is much different from previous years and requires the use of new vaccines, which will be a big challenge for China, where influenza vaccination rates are already low.
high-risk groups are more at risk because of the high rate of Streptococcus pneumoniae infection during the autumn and winter seasons.
" new crown, influenza, streptococcus pneumoniae, these three diseases common characteristics, are attacking the elderly, the death rate is high.
main targets of influenza and Streptococcus pneumoniae also include children.
but the good news is that we all have ready-made vaccines for the other two diseases.
I recommend that high-risk groups must be vaccinated, the elderly, chronically ill people, adolescents and children, as well as pregnant women, medical personnel, these are the World Health Organization point out the high-risk groups of influenza.
" Chen Weijun also holds the same view, in his view, from last winter to this summer, the emergence of the new crown virus even half a cycle is less than, we do not know what kind of posture it will counter-attack, so be cautious, steady play is the best response strategy.
"Don't expect a stick to kill it."
any new virus, we should stop, gradually grasp its situation, and finally annihilate it.
like a little flower, the process of fighting human beings and viruses is the process of constantly learning lessons and seeing the process of dismantling, how long this cycle is, no one can say for sure.
" odds are still great, but don't be paralysed, because you and I are susceptible.
," Zeng added.
, Zeng Guang also expressed his views on group immunity.
" European and American scholars mentioned the group immunity, do you know why absurd? Because the proposers are too young, Europe and the United States more than 10 years before the vaccination of infectious diseases, more vaccines than we, their country scientists my age, have never seen what measles epidemic is like, but I know ah, in 1959, 9 million people in China fell ill ah.
there was no vaccine at that time, it was mass immunity, did it succeed? After more than 1000 years of popularity, has the group been successfully immunized? Why can't you succeed before, and you can succeed in the new crown? Some young scholars rely on theoretical ideas, data models, including patting their heads.
if he had been older and experienced those things, he might not have thought so."
