Since it first appeared in China at the end of last year, Covid-19 has taken over almost every country in the world and killed more than 1.2 million people. The vaccine is not yet available. But there is hope that it is about to appear

Humanity is tired of quarantine. Of fear of the coronavirus. Of the reports of health departments, which every day show an increasingly alarming picture of morbidity.

The fact is: the dangerous virus continues to live its own life, and nothing can stop it. Is that a vaccine that will allow the formation of long-term immunity from Covid-19 and thereby give a chance to return to the usual pre-quarantine life.

Talks about the main potential "weapon" against coronavirus have been going on almost since the beginning of the year. Even then, different countries of the world began to develop a vaccine, and it is worth recognizing that some of them have advanced very far in this matter. So much so that it seems like a lifesaving shot from Covid-19 will appear in the near future.

Statistics. Brief but reassuring

As of Tuesday, November 3, the list of vaccines officially approved for clinical trials by the World Health Organization (WHO) includes 47 drugs from around the world, including the UK, China, USA, Turkey, Israel and many others.

For example, Israel on November 1, began the first phase of clinical trials, during which its participants received not only a vaccine, but also a placebo, and neither they nor the doctors know exactly who gets what. The drug has already been given to the first two volunteers. In total, about 80 people aged 18 to 55 will receive it at this stage.

The second stage, during which the drug will be tested on almost 1,000 people, is scheduled for December this year. If it is successful, then in April or May 2021 about 30 thousand people intend to get injections.

This means that in the event of a positive result of all stages of testing, Israel can receive its own licensed vaccine against Covid-19 in the summer of 2021.

Returning to the statistics from WHO, we note that a number of other countries have come closer to approving their vaccine even more, due to the fact that their drugs are in the third (final) phase of clinical trials.

For example, we are talking about the drug of the American biotechnology company Moderna, as well as the vaccine AZD1222 developed by the University of Oxford, which was the first of all vaccines "candidates" to enter the third phase of clinical trials and, therefore, will be tested on more people.

In total, according to WHO, about ten potential vaccines are at the final stage of clinical trials.

Predictions from WHO

There are at least two of them: optimistic and pessimistic.

The optimistic forecast is that by the end of 2021, within the framework of the international cooperation program created under the auspices of the WHO, it is planned to produce at least 2 billion individual doses of the coronavirus vaccine.

Ukraine, we note, previously joined COVAX, a global program to create an effective vaccine against Covid-19.

This, according to the country's chief sanitary doctor Viktor Lyashko, will help the country gain access to an effective immunological drug (as soon as it becomes available) and cover the needs of 20% of the country's population.

The pessimistic forecast says that before an effective vaccine is released into the mass circulation, the number of deaths from the coronavirus in the world could reach 2 million.

As of Tuesday, November 2, 1 213 324 people have already died from Covid-19. Information from the Worldometer website indicates that since the beginning of the pandemic, 47 434 036 people fell ill with this disease worldwide, more than 34 million of them were able to recover.

Ukrainian vaccine

Yes, ourcountry is working on its own vaccine. When President Volodymyr Zelensky confirmed this information last month, he said the drug was "unique and not like the other ones."

However, the head of state did not immediately disclose the details, since, according to him, the vaccine must still undergo clinical trials.

At the same time, based on the words of the Minister of Health Maxym Stepanov, the preclinical phase of the tests has been completed.

"This" candidate for vaccines "has already shown complete neutralization of the virus on living human cells," the minister said.

The next step is the clinical phase of the trials. Stepanov stated that with its positive results, the Ukrainian vaccine against Covid-19 may appear in a year.

Despite the development of its own drug, the authorities assure that if someone's vaccine is approved earlier, Ukraine will buy it "in any case."

Prior to that, it was repeatedly reported that the country was registered in all queues for receiving a vaccine against coronavirus. As soon as possible.

Basically, what do you need to know about a vaccine?

This is a drug designed to provide immunity against a disease by stimulating the production of antibodies.

It can include suspensions of killed or attenuated (weakened) viruses, as well as products or derivatives of microorganisms.

In other words, the vaccine "introduces" the human immune system to a neutralized or weakened virus. And when the organism encounters it in real life, it will be able to recognize the "enemy" and will already know how to deal with it.

The most common method of receiving the vaccine is injection, but some may be given by mouth or by nasal spray.

The manufacturing process for a new vaccine involves many steps that take time. The first stage is the detection of a new virus, followed by the preparation and verification of the vaccine strain, the preparation of reagents for testing and clinical trials (they include several phases).

The final stage is the approval of the vaccine, which in different cases can take from 1 month to a year.
