The research on the research of new coronary pneumonia vaccines has made progress. Several candidate vaccines studied separately by Chinese, Britain, the United States and German teams respectively, standing out of more than 100 similar studies around the world. Preliminary clinical trial data showed that after participating in the experiments' vaccination, the body was internal internal vaccine, and the body was in their bodies.The immune reactions occur, and no serious side effects are seen. The key third phase of the clinical test can be launched.It is also a question to hope that the vaccine will soon end the epidemic; even if the vaccine is successful, it is also a question to become the most needed by public resources in the world.The world of epidemic is neighbor, and some wealthy countries have dug out their minds. They must be preferred and excluded. After the vaccine is released, some people will hoard their accumulation and even try to use it as a political weapon that dominate the international order.
Sino -American and British research has progress
Vaccine effectiveness is not guaranteed
About 140 new crown pneumonia vaccine research projects around the world, about 20 candidate vaccines have begun to clinical trials, but most of them are still in the first or second stage test, and there are only a handful of key third stages.The first stage of the vaccine's clinical test is to confirm the safety of the candidate vaccine and whether there is serious side effects. The number of test persons is generally not dozens of people; the second stage test is generally hundreds of people.The reaction; the third stage is to confirm whether the vaccine can really make the vaccinator immune, or even if the virus is infected, the condition will be lighter.
On Monday, three candidate vaccines all announced the encouraging preliminary test data, which can launch the third stage of testing. They are responsible for the study of the Esley Kang team of Oxford University and the British -Rui joint venture, and Chen Wei, by mainland experts Chen Wei.Leading Kangxino Biological Corporation, as well as a cooperative team between the Pfizer Pharmaceutical Pharmaceutical Factory and Biontech in Germany.Studying the new crown pneumonia vaccine is against time, these three teams are in the world's leading position. In addition, the Mainland Chinese Medicine Group and the Beijing Kexing Biological team also cooperate with the UAE and Brazil authorities to launch about the third stage of tests for about 10,000 people; the United States; the United StatesThe third stage test of the Moderna team can also be launched at the end of the month.
In the past, there have been no vaccines for coronary virus. Scientists around the world have multi -way proceeds to develop vaccines in different methods. Fishermen's scattered nets help increase opportunities for success, but it does not mean that the vaccine can be released soon. If anyone thinks that there will be vaccines within a few monthsSave the world, no need to endure the immune now, it is likely to pay a painful price.German vaccine expert Jonas Schmidt-Chanasit even doubted that it was impossible to develop a super vaccine that everyone could be immunized for lifelong immunization after injection. It was more likely that there were multiple vaccines at the same time.In the future, humans will still be coexisting with the epidemic, and daily life cannot be fully reconciled.
According to previous experience, the first two stages of clinical trials, fast people have the opportunity to complete it for one and a half years, but the third stage will take several years at any time, the R & D virus vaccine is developed rapidly, and it takes 5 years before and after.The candidate vaccine that entered the third stage of testing was only 17% of the positive results.The second stage of testing to confirm that the vaccine successfully triggers antibodies. It can be completely immune to the vaccine. It is a matter of two yards. If the immune effect does not reach 70 % or more, it may not be able to stop the epidemic.Sino -German researchers have found that shortly after the patients with new crown pneumonia are healed, the level of antibody in the body has dropped significantly and may be infected again, which means that even with vaccines, the effect may be brief.
Vaccine is a global public financial
The United States is priority to violate public justice
There is no guarantee for vaccine research. Even if there is a vaccine, it may be reduced to a wealthy country forbidden, or it has become a tool for manipulating other countries to manipulate other countries.In the face of this epidemic situation, the international community did not help each other. Instead, the United States did not play a leading role. Instead, the United States first talked about the United States priority. Based on the injury, the supply of antiviral drugs in the next 3 months was almost bought by the United States.It caused European dissatisfaction.Earlier, Washington proposed a quick action plan to lock about 10 candidate vaccines that have the opportunity to success in the West, and sign an investment agreement with the pharmaceutical factory early. Once it is made to give priority to the United States, some US officials have stated that they meet all Americans's needs.Later, the vaccine was left to the people of other countries.
It is true that in addition to the United States, China, French, Germany and other countries have also signed pre -order contracts with their own or other country's pharmaceutical factories. They hope that the people will have vaccines in the future. However, the reasonable synergy guarantees the basic supply.The goal of Washington is that there will be 300 million vaccines in January next year. Behind the meaning of 300 million people in the United States as long as they are willing to inject, even if low -risk people can vaccine, this is the principle of violations of the road.Experts advocate that after the vaccine is launched, it should be used by the most needed persons, such as anti -epidemic medical care and high -risk groups around the world.After the production of vaccines in China, it will use it as a global public fortune and share it with other countries. European countries such as France also have also stated that all countries will be fair and reasonable to obtain vaccines. However, the United States has never made similar commitments.
In the United States, some comments speculate that after Chinese vaccine is made, it will be supplied to developing countries and the Belt and Road countries to expand the influence of diplomatic influence. However, regardless of motivation, they are willing to actively share the vaccine with the people of other countries.International Tongli cooperates with the development of vaccine sharing. Of course, the most ideal, the political reality cannot be done.The state was isolated from vaccine due to political reasons.Politics is also politically politically. The most dangerous situation of saving the world is that a country collects the world's vaccines, hoard it, and uses it to dominate the international order, or be a political weapon for the price.
