Innsbruck, Graz, Vienna – The cases are more and more – it has recently become known that in Alpbachtal, Tyrol, a child is ill. The vaccination discussions become heated. Viennese virologists now point to it science announced a 2015 study, which rejects the alleged benefit of "natural" infections. On the contrary, the study has shown that measles during the years of weak immune system of the patient. Lukas Weseslindtner and Heidemarie Holzmann of MedNe Vienna are quoted in the light of the current situation in epidemiological information on the virus.
"There is now valid scientific evidence that clearly shows the opposite and shows that measles cause several years of weakness in the immune system, which even leads to an increase in mortality due to other infectious diseases," wrote a virology expert in Vienna.
"The holes are not harmless"
The claim that vaccine opponents often raise doubts in favor of the measles vaccine is known that "natural" penetration of the measles "strengthens" the immune system. "It must always be remembered that the measles are by no means harmless, but they have a very high rate of hospitalization and complications (about 20 percent) … (…) Mortality rates are associated … According to the World Health Organization (WHO) still cause between 130,000 and 160,000 deaths per year, the researchers wrote.
In any case, the immune system plays an important role in the development of the disease. "On the one hand, certain cells of the immune system, such as dendritic cells, T and B lymphocytes are target virus cells themselves, causing them to lose those cells in early stages of infection and thus lead to leukopenia (loss of white blood cells; , emphasized the Virology.
Recent immune studies, mostly conducted with macaques as experimental animals, showed a different picture. It has been observed that the measles virus does not randomly infiltrate the lymphocytes but penetrates the memory cells via a specific receptor (CD150). In the context of leukopenia, memory cells are almost exclusively lost, which were formed in previous years in overcoming various other contagious diseases, "the researchers wrote. There was only a memory station that was specific to measles virus. Although this would mean lifelong immunity to the measles, but it is directly responsible for increased susceptibility to other pathogens.
Increased sensitivity to other pathogens
Scientists would then, in a costly statistical analysis, report the number of measles cases in England, the United States and Denmark from pre-vaccination during the introduction of measles vaccines to high rates of vaccination (from the 1950s to present) with mortality rates from other estimated infectious diseases .
The Viennese Virology writes: "It was clear that there is a correlation between incidence and impoverishment of other infectious contagious diseases. For example, if the incidence of measles in certain years was particularly high, it also increased the mortality rate of infection with other agents.
It is also interesting that the introduction of vaccination against measles did not only lead to a massive fall in those cases but also caused a significant decrease in mortality from subsequent infections. "The fact that this reduction was specifically associated with the introduction of vaccine against the measles and that it did not happen was accidentally proven, inter alia, in analogous to the effect of vaccination against pertussis on the mortality of infectious diseases, and the effect did not exist."
In analogy to the animal experiment results, it would be possible to indirectly estimate for humans how long damage to the pool of memory cells could be due to measles. Virology writes: "The results were unbelievable: the risk of dying from other infectious diseases was not only increased for a short time, but significantly increased over a period of two to three years after being subjected to measles."
