Ukrainians are wary of the mandatory vaccination for teachers introduced by the Cabinet of Ministers, as well as the inclusion of a vaccination certificate in the list of necessary documents for visiting public places and moving between cities. Many are confused by the likelihood of encountering side effects. Motivation to vaccinate decrease after looking at the incidence of Covid among the already vaccinated.

In Ukraine, the responsible institutions do not officially publish information on the incidence among those vaccinated against coronavirus. However, managed to get a response from the Health Center, which shed light on this issue. Based on the information provided by the Center, among all people who were admitted to hospitals with Covid-19 within 11 days of October, 6.3% were vaccinated.

How often do the vaccinated get sick?

You need to understand that a vaccine does not guarantee that you will not get coronavirus. The task of the vaccine is to alleviate the course of the disease if a person nevertheless falls ill after being vaccinated.

With the increase in the rate of vaccination, more and more often you can come across Facebook publications of Ukrainians vaccinated against the coronavirus that they still managed to get sick.

“I must say that both Irina Frantseva and I are vaccinated on time, everything is ok, but as they write in good romantic stories: they lived happily and got sick on the same day ... True, I have Covishield, and she has Pfizer. For her the course of illness is really light, and my body reacts very violently to the virus, with all its characteristic bouquet. At this stage, the temperature is constantly under 39, saturation 92, breathing difficulties, "wrote Yuri Chertkov on October 17, attaching a photo of his PCR test and covid -certificate. requested information from the Public Health Center about cases of hospitalization of vaccinated Ukrainians since May, when the mass vaccination began. The center provided data only from 11.10 to 22.10 (inclusive).

In just 11 days, 3066 people who received at least one dose of the vaccine were hospitalized.

According to our calculations, according to the official statistics of morbidity on the Center website, 48,929 people were hospitalised with coronavirus during this period. That is, among all those who ended up in the hospital with Covid-19, there were 6.3% of those vaccinated.

It is necessary to understand that quite a small number of the population is vaccinated in Ukraine. As of October 25, 2021, only 21.69% of citizens are vaccinated against Covid-19 in the country. The low rates of vaccination are especially indicative in comparison with Israel, Great Britain, Iceland and the USA.

If we imagine a hypothetical situation in which society would be divided into exactly two categories: 50% of those who were vaccinated and another 50% of those who did not receive the vaccine, the rate of hospitalized sick among those vaccinated could be higher and be up to 15%. Of course, these are only rough calculations that do not take into account how responsibly vaccinated citizens would wear masks and comply with quarantine restrictions. However, the trend is indicative.

If we talk not only about hospitalization, but in general about the incidence of coronavirus among vaccinated Ukrainians, then we can only guess how many of them suffered Covid-19 and were not hospitalized. Many Ukrainians who felt the symptoms of the disease did not do PCR tests, and some citizens did not even know that they were infected, because the disease may be asymptomatic.

In the world, the rates of hospitalized patients among those vaccinated are even higher. The Israeli health service in August 2021 admitted that over 60% of those hospitalized with coronavirus in the country were vaccinated.

Let's make a reservation right away: the percentage of infected is really huge, but it must be read correctly. If we carefully consider the case of Israel, then in total three times more people than in Ukraine were vaccinated - about 60% of the population. If the ratio were approximately equal, there would be fewer hospitalizations among the vaccinated.

For example, the incidence rates of vaccinated people in Iceland, where more than 90% of people were vaccinated, would be frightening.

Whatever the statistical amendments are, the high incidence of people vaccinated against coronavirus is not encouraging, because it is thanks to vaccination that herd immunity should be created, and the pandemic should be defeated.

Delta strain leads to sad statistics

Why do vaccinated people get sick? Let's ignore the obvious fact that fake vaccination certificates are available in Ukraine, and let's start right away with the fact that the vaccine efficiency itself is below 100%.

Different studies of vaccines show different "throughput" for the virus. When a person who has received the full dose of the vaccine becomes infected with the covid doctors call it a "breakthrough of the infection" through the immune defenses. In a sense, a "breakthrough" is any disease that manages to enter the body.

Infectionist Olga Golubovska emphasizes: a vaccinated person and an immune person are different concepts, and it is important to speak at the state level precisely about the number of immune people. It is necessary not only to vaccinate citizens, but also to check the presence of protective levels of antibodies.

It is believed that the drugs recommended by WHO create antibodies from the "corona" in 70% of cases or more. There is no need to talk about one hundred percent protection, because antibodies may not be produced in people with pathologies of the immune system, in cancer patients, and the elderly. Usually, those who do not form antibodies for some reason are offered to be vaccinated with another vaccine.

The imperfect effect of the vaccine is superimposed on the cyclical nature of the pandemic, which leads to the formation of new genetic variants of the pathogen. All drugs used by WHO were developed on the basis of the original SARS-CoV-2 coronavirus strain found in Wuhan, China. Since then, the virus has mutated many times, thousands of its different variants have appeared, which prolong the fight against the epidemic: according to infectious disease specialists, it will last at least another 2.5 years.

If we held back the intense circulation of the virus, we would also reduce the likelihood of new mutations emerging. By the way, the indirect task of vaccination is precisely to prevent the emergence of new strains. If the carrier of the original strain of coronavirus conditionally infects an average of two people, then the carrier of the Delta strain - four.

Since vaccines were developed from a specific strain of coronavirus, the antibodies generated by them are partially unable to fight new mutations.

The international scientific journal Vaccines published an article on the effectiveness of the Sputnik V vaccine against coronavirus strains. According to this article, for the Beta strain, the ability to neutralize the virus falls by 3.1 times, for Gamma - 2.8, for Delta - 2.5 times.

In August, Israel also compared the immunities of those who were vaccinated with Pfizer-BioNTech and those who were organically ill with Covid-19. It turned out that those fully vaccinated were 13 times more likely to be infected with the Delta strain. In addition, research has shown that natural immunity, together with the first dose of the vaccine, provides longer lasting protection.

It is worth noting that the study authors themselves caution about a number of factors that may have influenced such results. We are talking only about one of the vaccines and only about a specific strain of the "corona". The study did not take into account how responsibly vaccinated and unvaccinated adhered to quarantine restrictions, in particular, wore masks.

Every day there is a risk of a new strain emerging, against which the current vaccines will be practically powerless. However, the mutations known to date do not make the virus completely unrecognizable for antibodies, but only change certain parts of the viral proteins. The chances of picking up a dangerous strain of the virus are still about half as much for a vaccinated person as compared to a person who has never been vaccinated.

Vaccinated people should be more vigilant

Increasingly, epidemiologists claim that the world is placing too much emphasis on vaccination, while other components of anti-epidemic measures are also important. This, in particular, and ventilation of premises, and wearing masks. Increasingly, vaccinated people stop following other rules that prevent transmission of the virus. For example, they may go into long-term direct contact with sick people, suggesting that they will be protected by antibodies. This is another reason why so many vaccinated people can get sick in the world.

However, you should not tempt fate. Particularly important is the patient's vigilance for 1.5 months, starting with the first vaccination and ending about 21 days after the second: it is necessary to wait until the body forms immunity. In the intervaccination period and early after the second injection, it is especially important not to visit crowded places.

The Israeli medical company Meuhedet analyzed the data of 100 thousand of its clients and received the following results: from the 7th to the 14th day after the second dose, the vaccination efficiency averages 89%. But after two weeks, it increases to an average of 96%. Therefore, the company came up with a proposal not to give a vaccination certificate immediately, but to do it only after two weeks. This is to ensure that the vaccinated do not risk their health in public places until they receive full immunity.
