One of the frequent criticisms of vaccination and the introduction of epidemiological restrictions for the unvaccinated (or covid-pass), which can be heard in recent months, is that the vaccinated have also spread the virus.

Truth be told, situations in many countries with high vaccination rates such as Israel have shown that approved vaccines do not effectively protect against the delta variant as they have from others who have dominated before.
The trampoline gave instructions on how, where and with what vaccination adolescents are vaccinated.
The delta variant of the SARS-CoV-2 virus has been shown not only to be more contagious but also to be able to bypass in part the defenses of the immune system created by vaccination. In addition, vaccine protection has been shown to decrease over time.
Reports published by the Centers for Disease Control and Prevention (CDC) have found that the effectiveness of protection against infection with the delta variant provided by vaccines approved in that country has dropped by about 90 percent to about 66 percent.
Criticisms of vaccination and vaccinations, which have been introduced by many countries, conclude that such a regime is meaningless because the virus can spread even in meetings in which only vaccinated people participate.

In doing so, they usually refer to some research, which shows that the viral load, i.e. the concentration of the virus in the nasal mucosa in unvaccinated people is similar to that of vaccinated people, these facts were later refuted. .
In addition, they note, vaccinated people will feel safer, so they will not pay enough attention to other epidemiological measures, such as wearing masks, washing their hands and keeping their distance, especially indoors.
But critics of vaccinations and the past concluding so make more mistakes because they invoke bad places. That is to say, the research has clearly shown several important facts on which the conclusions we will present in this text are based:
1) the probability of infecting a vaccinated person is much lower than that of infecting a non-vaccinated person, vaccines protect about 66%
2) the viral load in vaccinated and unvaccinated people is not the same when all infected people are seen – with and without symptoms
3) the viral load in vaccinated people decreases much faster than in unvaccinated people
4) it is expected that people who have been vaccinated will retain a greater majority of caution than people who have not been vaccinated, many of whom relativize the danger of kovid 19
5) Finally, there remains an indisputable fact that vaccinated people are incomparably less likely to become seriously ill and die, even when it comes to deltas.
Most vaccinated people will not be infected
The fact that the delta is able to boost the immune system of vaccinated people does not mean that the probability of infection is the same in vaccinated and non-immunized people. For example, a study published by the CDC in late August showed that from May to July in Los Angeles, people without vaccination had five times the rate of covid infections 19 of those vaccinated.
Vaccine against kovid and influenza at the same time – sure
In other words, the spread of infection among vaccinated people is significantly reduced. The fact that they may be infected does not mean that they will be infected in the same percentage, meaning that the risk of socializing with vaccinated people is the same as with those who are not vaccinated.
The viral load in vaccinated and unvaccinated patients is not the same
Some research has shown that the viral load in the nasal mucosa of unvaccinated and unvaccinated people is similar.
However, a major analysis of the delta’s transmission, which is based on data from the British program REACT-1 led by scientists led by a team from Imperial College London.
Every few weeks, more than 100,000 British volunteers were tested, and the study showed that vaccinated people had, on average, a lower viral load than those who were not vaccinated.
Paul Eliot, epidemiologist of Imperial, In order Nature he explained that these results are different from other similar studies because his study randomly sampled the population and included people who tested positive even if they had no symptoms.
The viral load in vaccines decreases much faster than in vaccines
Research shows that vaccinated people who are infected with the delta strain are less likely to be infected than those who are vaccinated.
This was, among other things, indicated by research by Singapore scientists who monitored the viral load between vaccinated and unvaccinated SARS-CoV-2 virus on a daily basis.
During the first week of infection, the load of the delta variant was similar in both groups, but it fell rapidly between vaccines after the seventh day.
Because of this, Singapore experts, such as the US CDC, have recommended that vaccinated people continue to wear masks at home, where a larger number of people gather.
Viral immunologist Luka Čičin-Šain, who works in the famous Helmholtz The Center for Research on Infectious Diseases, explained to the Croatian media the reasons why the viral load in vaccinated people could decrease more rapidly.
“This is logical because the vaccine given in the muscle tissue cannot create the same amount of immunity in the mucosa as in the muscle tissue. Therefore, the immunity in the mucosa of the upper respiratory tract of the vaccines will be a little lower, so the virus will start with upper respiratory tract infection. However, relatively soon after, they will come into contact with the cells of the defense system, which will respond very quickly to the infection and suppress the virus. ” , said Chichin-Shain.
It is to be expected that vaccines will continue to comply with the measures
Since even vaccinated people can spread the virus, the CDC recommends continuing to comply with epidemiological measures, especially to wear masks when meeting at home and to wash their hands regularly.
Although vaccinated people have reason to feel more relaxed because the vaccine protects them solidly from infection, and even more so from hospitalization and death, on the other hand, they are expected to have more confidence in the recommendations of experts. and health organizations.
That said, this is exactly one of the main reasons why they have been vaccinated.
Vaccinated people rarely get seriously ill and die
CDC research cited earlier found that unvaccinated people are 29 times more likely to be hospitalized than vaccinated people. In conclusion, the authors also pointed out that the probability that vaccines will end up in intensive care and on a respirator, and also that they will die significantly higher than for vaccines.
In addition, numerous studies show that complications, such as blood clotting and multisystem inflammation of the organs, are more common in hospitalized patients than in those who have been treated without symptoms for 19 years.
Several studies have already shown that patients admitted to hospital with kovid 19 had complications due to coagulation disorders involving the heart, brain and peripheral vascular system, which led mainly to myocardial infarction (MI), stroke. ischemic and venous thromboembolism.
During the early months of the pandemic’s spread, several autopsy studies revealed systemic microthrombosis in several organs, including the lungs, heart, and kidneys, suggesting that thrombosis could contribute to frequent and often fatal multisystem inflammation in patients. with severe covid.
