So, the new generation of cells has the same number of chromosomes.

That's because, as we know, the flu is a disease of rapid proliferation and that imposes risks to the lives of some people. The vaccine has the ability to reduce the risk of a person being infected with the flu virus by 50%, this percentage is essential for people who are more sensitive to this virus such as the elderly, pregnant women and people with respiratory problems.
