It helps it gain immunity
Because immune system is weak in children than elders.
no
Some people are allergic and if in contact with the skin, could cause a rash.
The body fights against smallpox through the immune response, primarily by producing antibodies and activating T-cells. When exposed to the smallpox virus, the immune system recognizes it as foreign and generates specific antibodies that neutralize the virus. Additionally, cytotoxic T-cells target and destroy infected cells. Vaccination also plays a crucial role, as it primes the immune system to recognize and respond quickly to the virus, providing immunity without causing the disease.
There are quite a few ways to become immune to smallpox. One way is that you can be infected with the disease Cowpox. Which is not deadly in anyway but is a disease nobody wants to have. Another way is, you can infect your self with smallpox and give yourself a mild case of it. It is proven that once you had smallpox and you survived you never get it again, by infecting yourself mildly you can become immune to it. Correction mild case of smallpox is cowpox if u become infected with cowpox u become immune to smallpox and cowpox for the rest of your life it is like a vaccination but instead of being shot with it u actually become sick but once you get over it your completely immune to it or any other more serious case of the illness.
Vaccination is the method used to prevent diseases like smallpox by introducing a weakened or killed form of the pathogen into the body to stimulate the immune system to produce antibodies against it.
African Slaves were immune to it and the origin is unknown?
The immune system is responsible for protecting the body against foreign substances like bacteria, viruses, and toxins. It does this by identifying and destroying pathogens that can cause harm to the body. Through a complex network of cells, tissues, and organs, the immune system works to keep the body healthy and defend against infection.
Yes, the vaccine used to prevent smallpox contains a live virus known as vaccinia, which is a related virus but not the smallpox virus itself. This live attenuated virus stimulates the immune system to provide protection against smallpox. While the vaccine is effective, it can cause side effects and is generally not given to the general public since smallpox has been eradicated.
Some can. One thing that can happen, is that if your immune system is fighting one infection, it can leave you vulnerable to a second one. Some bacteria have been discovered to produce chemicals that destroy immune cells in order to defend themselves.
Anyone not immune to the virus (not a common virus anymore though)
HIV, aids, hepatitis, and pretty much any serious disease you can think of
