Unusual interactions between viruses and vaccines discovered University of Illinois scientists studied the herpes virus that infects chickens. Findings provide new insights into interactions between live virus vaccines and the viruses themselves.

The study provides direct evidence that the vaccine and the virus can infect the same cells of living organisms and use common molecular tools to attack other animals.. In this case, they were chickens.. Research has focused on Marek's disease, a viral infection that spreads when a chicken inhales fragments of dead skin or feather tissue from an infected chicken..

Revealed the mystery of the interaction of nerve cells Scientists tried to understand how the virus passes from one host to another. This work is done not only to protect chickens in the poultry industry, but also because other viruses, such as those that cause chickenpox in humans, use similar mechanisms when they pass through the respiratory tract and infect lymphocytes.. In poultry farming, vaccination is also used, and chickens are vaccinated against Marek's disease.

The chemical basis of the interaction of organelles inside a living cell has become known. In some cases, even chickens in an egg are vaccinated..

It uses live modified vaccines, which are considered the most effective in protecting against the disease.. Vaccines made from live viruses are better than others at training the immune system to recognize pathogens. But it turned out that they do not lead to the complete elimination of the virus.. And this leaves room for the interaction of a real virus and modified viral vaccines, which leads to the evolution of the pathogen and its increased infectivity..
