The State Council joint prevention and control mechanism held a press conference on May 31st to introduce the situation of epidemic prevention and control and vaccination. Since May, a total of 50 new confirmed cases have been reported in China, and new confirmed cases or asymptomatic infected people have been reported for 18 consecutive days, involving many provinces.The epidemic situation is characterized by rapid spread and strong spread of strains. The the State Council Joint Prevention and Control Mechanism has sent a working group to Guangdong to guide the handling of the epidemic..What other latest news is worth paying attention to? Let’s look at it together-
How is the national vaccination going?
As of May 30, the country has reported vaccination with Covid-19 vaccine.639.172 million doses. Vaccination has been accelerated on a large scale, with an average of 12.47 million doses per day since May, 2.58 times that of April, with the highest dose per day exceeding 20 million.We should continue to accelerate vaccination and build the Great Wall of Immunization..
How to arrange the recent vaccination work?
From June 10 to 30, the second dose of vaccination was mainly carried out for these target groups who had already received the first dose.However, for those with special needs, such as going abroad and other epidemic prevention and control, continue to inoculate the first dose of vaccine.After July, the first and second doses of vaccination will continue to be fully promoted., do a good job of COVID-19 vaccine inoculation in an orderly manner.
Is COVID-19 vaccine going to be charged?
At present, our vaccination work is based on the needs of epidemic prevention and control in COVID-19, combined with the actual vaccine supply and the vaccination work arrangement at this stage. We advance by steps, highlight key points, and give informed consent.The principle of voluntary and free vaccinationTo vaccinate all kinds of people step by step.Everyone must not believe in rumors, let alone spread them..
Local sporadic cases have appeared in some places one after another. Will the normalization prevention and control measures be adjusted?
Recently, the local epidemics, especially in Guangzhou and Shenzhen, were all caused by the import of foreign viruses.Shenzhen was caused by the mutant virus first discovered in Britain, and the epidemic in Guangzhou was caused by the mutant virus first discovered in India. The spread ability of these two viruses was enhanced than before..
According to this new situation, all the tools in the toolkit for preventing and controlling the spread of epidemic should be called out, and it should be adopted and implemented accurately and forcefully.It may be strengthened and adjusted accordingly in terms of implementation strength, scope and duration..
Any suggestions for the Dragon Boat Festival holiday?
The advice given by holiday activities related to the past has not changed much. It is still that individuals should take precautions. Personal preventive measures include wearing masks in public places, paying attention to personal hand hygiene and respiratory etiquette.
In addition,People in medium-risk and high-risk areas should try to avoid unnecessary travel and reduce the cross-regional spread of the epidemic..
If you have fever or respiratory symptoms during the trip, you should quit the trip in time, avoid contact with other people and seek medical advice in time.Especially to the standardized medical institutions with fever clinics..
Is the domestic COVID-19 vaccine effective for the mutant strain?
We carried out a cross neutralization experiment in China by using the serum obtained from overseas Phase III clinic, including strains found in South Africa and Britain, including epidemic strains found in different regions of China. Up to now, these sera can still react well with these viruses.It should be said that the vaccine still has good protection..
The variation of the virus is eternal, it happens naturally, and at present,As long as the mutation of the virus can be controlled, the vaccine should still be able to protect the current situation for a long time..
Under some special circumstances, enterprises in China are also ready to develop new vaccines in response to sudden major mutations.Vaccines against mutant strains can be developed quickly..
What are the contraindications of Covid-19 vaccine?
Technical Guide to Vaccination in COVID-19 (First Edition)Five situations of vaccination taboo are specified, including:
1. When Covid-19 vaccine or similar vaccine was inoculated before.Have had allergies, this isAn absolute taboo.
2. Previous vaccinationHaving had a severe allergic reaction.
Step 3 suffer fromUncontrolled serious nervous system diseasesYes.
4. beingFeverOr suffer fromAcute diseaseorPatients with acute attack of chronic diseases.
5. Uncontrolled patients with severe chronic diseasesThese are relative taboos.
(The third, fourth and fifth categories are relative taboos. In the course of clinical research, it is not found that vaccination of these groups of people can lead to serious adverse reactions, but it is listed as a taboo for vaccination in order to prevent and guard against it. )
Some taboos, such as fever, acute disease and acute phase of chronic disease, are temporary. When these circumstances leading to taboos no longer exist,You can be vaccinated after recovery and stable disease control..
·Breast-feeding and menstrual women are not taboo for vaccination. Patients with depression, anemia, heart stent, etcIf the drug is well controlled, the condition is stable or you can live a normal life, you can also be vaccinated.
Whether you are taking antiviral drugs and can be vaccinated with Covid-19 vaccine depends on the condition at that time.If you can’t judge yourself, you can consult a clinician to judge whether you can be vaccinated..
What’s the difference between one shot, two shots and three shots?
What we are currently usingInactivated vaccine, adenovirus vector vaccine and recombinant protein vaccine.. These three types have their own characteristics in vaccine composition, production technology, immune principle and immune procedure.
·inactivated vaccineIn the preparation process, the virus is inactivated after a large number of cultures, purified after verification, and then turned into a vaccine. The main feature of this vaccine is that the technology is very mature, it has been used for hundreds of years, and the quality is very stable.Side effects are relatively few., 2 to 8 degrees storage, easy to transport and use.This vaccine is usually given with two injections.The first needle stimulates the immune system to produce memory cells, and the second needle induces a stronger antiviral immune memory response.
·Adenovirus vector vaccineThe S protein of the virus is introduced into adenovirus type 5 vector, and this antigen is introduced into cells by virtue of the ability of adenovirus to enter cells efficiently, and its expression stimulates the immune system. Because of its high efficiency and relative lack of resources,One shot is the whole process of immunity., you can improve the vaccination rate of the whole process of immunization.
·Recombinant protein vaccineIt is to use genetic engineering technology to set up engineering cells to express virus S protein, so that it can be expressed efficiently, and then it will become a vaccine after extraction.In most cases, this vaccine is given three injections, and the best immune response will be obtained after three injections..
These three kinds of vaccines are safe, effective and quality-controllable.The public can safely choose any vaccine for vaccination.
The public must complete the whole process of vaccination and cannot give up halfway.Otherwise, the best protection effect set by the vaccine will not be achieved, that is, preventing virus infection, preventing illness and preventing severe illness.
We can’t relax other public health prevention and control measures when we don’t reach the group immunity barrier among the people.. We haven’t reached the group immunization standard set by the state. After reaching the standard, the country will have corresponding new prevention and control guidelines.
