Are there people who are immune to poliomyelitis?

Yes, there are people who are immune to poliomyelitis. Immunity to polio can be acquired through natural infection or through vaccination. Natural immunity occurs when a person is infected with the poliovirus and their immune system successfully fights off the infection. This can result in lifelong immunity to all three types of poliovirus. Vaccination against polio can also provide immunity. The polio vaccine is a safe and effective way to protect people from the disease. It is given in a series of shots, and it is highly effective in preventing polio.

In addition to natural immunity and immunity through vaccination, there are some people who have a genetic resistance to polio. This means that they are less likely to become infected with the poliovirus, even if they are exposed to it. This genetic resistance is rare, but it does exist.
