How many times have you heard this sentence: so-and-so got corona despite receiving the full dose of vaccine and booster doses? Many of us hear it daily and the like despite the fact that the world is trying to recover from a pandemic that has paralyzed all parts of the world for about 3 years and left millions dead and injured.
In this regard, a new study from the “Oregon Health and Science University” in the United States reported that vaccine-preventable infections create a lot of immunity against Covid-19 and may help to eliminate this epidemic.
Vaccine-progressive infections are those that occur despite a person receiving full doses of the vaccine as well as booster doses, because receiving them puts the virus under an evolutionary strain that forces it to find more ways to infect people at its expense. The ability to cause pathogenesis, i.e. to cause disease-related symptoms.
During the study, the researchers found that as infections with the Omicron sub-mutations, which are included in the vaccines, increase, and as global vaccination and advertising campaigns continue, an increasing proportion of the world’s population acquires strong immune responses that may protect against it. . Future types of this virus
The results of the study, published last week in the journal (Med), relied on the use of blood samples to determine the immune response to the virus, as the researchers measured a strong immune response among blood samples obtained from 99 employees.
“Early in the pandemic, we had very high mortality in some vulnerable groups, such as the elderly in nursing homes,” said lead researcher Marcel Kerlin, assistant professor of infectious diseases. But this reality is slowly changing, and our study supports it. The idea of vaccination is a pathway to a milder illness, so even if you’re older, it seems that if you get reinfected, you’re much less likely to get seriously ill than you were at the beginning of the epidemic.
Fikado Tavisi, associate professor of molecular microbiology and immunology, and co-author of the study, predicts a stronger immune response among people who receive the new bivalent booster vaccine that targets the omicron BA.4 and BA.5 subtype mutations.
“We expect that updated vaccine strategies with type-specific regimens will significantly improve the breadth of the immune response and provide better protection against virus variants,” he adds.
Unlike at the beginning of the epidemic, the emerging coronavirus is no longer “new” to the human immune system, and immunity has now been acquired as a result of most of the world’s population being vaccinated, infected, or both, meaning that the virus faces a more effective immune response with each new infection. to be
The lead researcher believes the new study likely reflects the fact that the virus is evolving to become more transmissible but less damaging. “Evolutionary pressure drives the virus to find more ways to infect people at the cost of disease,” Kerlin adds, meaning the ability to cause disease-related symptoms.
The collected data shows that the total number of people infected with the corona virus worldwide exceeded 615 million people until yesterday.
The latest information available on the American website “John Hopkins University” indicates that the total number of injured has reached 615 million 90 thousand 836 people.
The total number of deaths from this disease reached 6 million 536 thousand 963 people. The total number of vaccines administered worldwide increased to 12.252 million 972 thousand 639 doses.
It is mentioned that the vaccine dose and the number of population to be vaccinated are estimates that depend on the type of vaccine that the country injects, that is, whether it is a single dose or a double dose.
