The 2019 ncov coronavirus, which emerged in the Chinese city of Wuhan late last year, is spreading to new countries. Russia manages to avoid an outbreak of the epidemic, there are isolated cases of the disease.
Countries, including Russia, are developing a vaccine against the coronavirus. This issue should be analyzed in more detail. This article will discuss the topic of the coronavirus vaccine.
Coronavirus is a family of 40 viruses. It affects the nervous, respiratory, digestive systems of humans and animals. The disease can lead to acute pneumonia and serious consequences. In structure, spike-shaped processes are similar to a crown, which is why this virus was named so. Scientists discovered the disease back in 1960.
When will the coronavirus vaccine be developed?
Since January 2020, rumors have been circulating that a vaccine against coronavirus from China has been invented, as of March 2020, a hundred percent cure for such a disease has not been invented, the issue of vaccine production is acute. The coronavirus is already rampant in many countries, because of this, it is not only China that is looking for an antidote. The fact is that a person with a coronavirus does not develop immunity, which means that he can become infected again, infect others.
Creating a vaccine requires a serious approach, thousands of people's lives are at stake. Thanks to new technologies, the developed medicine promises to be promoted. In China, a vaccine was recently found, but before being used on humans, it will be subjected to a series of experiments. In case of successful tests, the drug will become available in two years, and now it is too early to say that the vaccine has been invented, these are just developments.
Rospotrebnadzor admitted that there are no such precautions that will help to 100% avoid infection. In order to reduce the risk of coronavirus disease, it is worth adhering to general rules.
Why is it taking so long to develop a vaccine?
It has already been mentioned that the human body is not able to develop immunity against coronavirus, this creates serious problems with the development of a drug. Before launching the drug in the general masses, it is necessary to make sure of the effectiveness, safety, long-term experiments on animals are required, which are not always successful.
But, if the experiment on experimental subjects is successful, the vaccine will be sent to special laboratories for testing, after which they will begin testing on a limited number of people. All medicines are required to undergo certification, the duration of which takes up to eighteen months. Thus, all these factors make it difficult to quickly create a vaccine.
Some scientists believe that in a favorable scenario, the drug will become widespread only in two years, before the vaccine can only be used in places with a strong epidemic.
Scientists are skeptical about the emergence of a new cure for coronavirus, they argue that it will harm people, increase the mortality rate. It is necessary to know the first signs of a possible dangerous disease, there are many of them, but the main ones are:
- heat;
- ailments;
- lack of appetite;
- dizziness;
- decreased appetite;
- fever;
- redness;
- cough;
- labored breathing.
Coronavirus is transmitted through the mucous membrane, so it must be protected. Do not touch your eyes and mouth with dirty hands, after the street, always wash your face and hands with soap or treat with an alcohol-containing agent.
Which countries started the development of the vaccine
Coronavirus of the 2019 ncov type spreads quite quickly, in addition, its incubation period reaches 14 days, which means that the virus in the human body persists all this time and is able to be transmitted to others through the mucous membrane. In 23 countries, symptoms of coronavirus have already been found: the USA, Canada, only the continents of Africa and South America remained unaffected.
Because of this precarious state of the states, they began active drug development. Countries such as Hong Kong, the USA, Australia, China and France are participating in the studies, the first trial vaccine was invented in Hong Kong. At the moment, a quarantine has been declared for entry and exit from countries, on March 11, this disease was recognized as a pandemic and an increase in infections is expected in different countries.
However, the Chinese medicine, when applied, shows good results in the epicenters of the epidemic, patients do not have complications, and the percentage of those cured is growing every day. So, in China, more than two thousand people recover every day, while only a little more than a hundred are infected.
Will the flu shot help against the new coronavirus?
If a regular flu shot had successfully fought a new disease, then there would be no epidemic. People who were vaccinated in the fall of 2019 would not have been exposed to the infection, while the rest would have been vaccinated later. Even a vaccine against pneumonia against coronavirus will also not help, the essence of the vaccine is that bacterial cells are introduced into the human body in a small dose, after which the body develops immunity to diseases, but the Chinese virus does not have such properties.
Scientists are looking for a vaccine that would help create immunity to the virus in the human body, because the 2019 ncov species is highly mutated and the usual vaccines were ineffective in combating it. Due to the lack of a cure, this disease is very dangerous and spreads rapidly around the world and, unfortunately, one injection will not be enough to cure.
But this does not mean at all that you do not need to be vaccinated, they are primarily aimed at eliminating a possible infection with the flu, from which you can die.
As of March 14, 2020, the following data on coronavirus is known:
- the number of infected exceeded 145,000;
- the number of recovered 71600;
- 5429 people died due to infection with coronavirus.
Already in more than 120 countries isolated cases of infected people have been found. A state of emergency has been declared in the world, the authorities are restricting air traffic, tightening control at railway stations, urging to be vigilant and protect your body even from SARS, sore throats or colds.
Don't panic when you read coronavirus news. First of all, you should take care of your own health and safety. It is necessary to avoid too crowded places, as well as contact with people who are sick, even with a common cold. If symptoms are found, be sure to consult a doctor, in no case do not allow self-medication.
