One of the most widespread methods of reducing infectious diseases worldwide is vaccination, which still has limited effectiveness in a group of patients - they are newborns.

The mother can give the baby immunity

More effective vaccines during pregnancy

A recent study by the Massachusetts Center for Science, MTI and Harvard University's Ragon Institute found that pregnant mothers can give immunity to their newborn children through vaccination. Because of the research it may be more effective to develop vaccines during pregnancy. "Newborns are coming to the world with a completely immature immune system that needs to learn to combat both harmful and beneficial bacteria in the environment," said Galit Alter, a professor at the Ragon Institute, "one of the authors said. to make a difference between the hostile and the useful morbidities, while the baby in the womb carries maternal antibodies through the placenta. The exact process by which antibodies are transmitted is not yet known, but understanding can be key in the development of more effective pregnancy vaccines, so that they can still produce stronger vaccines for the smallest patients? the professor said.

They also took blood samples from a cord

Even with some diseases, such as bends, the mother is able to pass the antibodies on to the infant before she can be vaccinated herself, but a more serious disease than less effective delivery of antibody in the case of valid child polio. In an examination of exactly how the mother gives her child the antibody, Galit Alter and her team introduced a new method. Blood samples were taken from mothers and semen - which, in addition to blood and nutrients, provide immune factors against infertility in infants - and tested for the presence of antisera.

NK cells are most effective

The study found that the placenta transferred antibodies into the baby's body that activate natural germ cells (NK cells), which are key components of the natural immune system. Numerous immune cells of newborns are still immature to provide effective protection, however, NK cells are among the most potent immune cells in the early days of infancy. Researchers have also found in the flu and RSV inflammatory infections tests that the placenta has delivered antibodies to the baby's body that have activated NK cells. In addition, we have discovered the characteristics of antibodies that regulate selected functions in the litter: these can be incorporated into the most recent vaccines, improving the ability of the mother and child to have antibodies.
