Measurements are not a harmful disease in childhood. In the worst case, an infection can be fatal. Many are known. But researchers from the Paul Ehrlich Institute (PEI), in collaboration with researchers from the UK and the Netherlands, have now discovered that measles viruses have erased part of their immunological memory in recent years.
This means that infected people are more susceptible to infections with other pathogens after surviving the disease.
In Germany, measles vaccination will be mandatory from 2020 onwards. Then children, students and some adults should prove they are vaccinated. Not for no reason – because infections increase, even measles should be wiped out for a long time.
For example, the European Center for Disease Prevention and Control (ECDC) talks about the resurgence of measles in Europe. Five countries, including Germany, where deliveries are still endemic ̵
Proposals can be fatal
Infected proposals can be fatal in severe cases. In addition, the virus weakens the patient's immune system to other pathogens. For example, measles infections are more likely to lead to other infections such as bacterial lung or middle ear infections.
A cohort study of measles also found that ten to fifteen percent of children still have symptoms five years after measles infection. there was a significant impairment of the immune system. This in turn leads to an increased incidence of additional infections. "The vaccine proposal is not only important in protecting against measles virus, but also protects against the onset or serious development of other infectious diseases," emphasizes Professor Klaus Cichutek, President of the Paul Ehrlich Institute. It protects the immune memory, which can be severe in measles infections.
According to the Paul Ehrlich Institute, the results obtained today confirm that the immune system after measles infection has almost forgotten which pathogens it has previously been associated with.  For this reason, ferrets were first vaccinated against the flu and some animals were infected with a mutant canine distemper virus associated with measles virus. According to the report, animals infected with the canine distemper virus lost most of the flu antibodies and had a more severe course of the disease compared to animals not previously infected with the virus when they were subsequently infected with the virus flu.
