The symptomatic infections fully vaccinated against the new coronavirus should not surprise us, emphasizes through iefimerida.gr the Doctor of Molecular Biology of the University of Toronto and permanent researcher at Mount Sinai Hospital, Ioannis Prassas, and refers to the function of vaccines in an attempt to understand the protection they offer.
"It's a battle against time. Many people are confused. Completing the vaccination does not act as a mental shield outside our nose that prevents the virus from entering. What vaccines do and protect us is to reduce the body's response time. ", explains.
The body of the vaccinated person detects the virus within a few hours, instead 7 to 10 days otherwise
According to Mr.. Leeks, before vaccination, from the moment the virus enters our body through the nose and infects the first cells in the mucosa, It would be at least a week before he was noticed by the border guards-cells to take him to the "factory" and finally fix the immune tools (antibodies, exterminator cells etc.) needed to limit it. Within this week, the virus sometimes manages to enter the lungs undisturbed and cause pneumonia and systemic inflammation.
"On the contrary, when we are vaccinated, instead 7-10 days, it takes a few hours for our boost immune cells to be alerted, who sit patiently in our lymph nodes and silently wait for a signal to immediately produce the immune tools they have already studied from the vaccine. So, the reaction window becomes much smaller and the virus does not manage to make a serious cycle of infection in the deeper respiratory tract. In the few hours it usually stays just on our nose (in the upper respiratory tract) and causes a mild cold ", comments the co-director of the research team, who together with Professor Eleftherios Diamantis are researching, including, the long-term immune effects of infections.
For some, the immune system is "weakened" and thus valuable time is lost.
In some people, however, usually older or vulnerable groups, Boost immune systems are "weakened" and take longer to properly alert and activate defense mechanisms after a possible re-infection. Giannis Prassas points out that "in these cases time is lost and so the virus catches and makes accidental infections. In the vast majority of cases, Nevertheless, full vaccination deprives the virus of the necessary vital time and so they do not get very seriously ill ".
10 with 15 The risk of getting the disease with vaccines is many times lower
In each case, full vaccination reduces approximately 10 with 15 times the risk of serious illness or even death from the virus. "This is a big risk reduction. Such as, already, we know, the age-weighted mortality of the virus is approx 2-15 times higher than the mortality of the influenza virus. That is, for most the risk of serious illness and death after full vaccination becomes equivalent to the risk of seasonal flu. That is, it is not zero. Some people who have been vaccinated with the virus will continue to die, as they die from the flu virus ", says the Greek researcher.
And it completes with meaning: "And because SARS COV2, especially the Delta strain, is much more contagious than the flu virus, even with the same mortality is expected to give more deaths per year. The virus came to stay. From 12 years and over, for the time being, what we need to do is prepare our defense for the first contact with him ".
