immunisoituja

Immunisoituja refers to individuals who have developed immunity to a particular disease. This immunity can be acquired naturally through prior infection or artificially through vaccination. When a person is immunisoituja, their immune system has the ability to recognize and neutralize the pathogen that causes the disease, preventing them from becoming ill or significantly reducing the severity of their symptoms.

Natural immunity is acquired when the body fights off an infection. During this process, the immune system creates antibodies and memory cells specific to the invading pathogen. If the same pathogen is encountered again, these memory cells can quickly mount a strong defense.

Artificial immunity is typically achieved through vaccination. Vaccines introduce a weakened or inactive form of a pathogen, or specific components of it, to the body. This exposure stimulates the immune system to produce antibodies and memory cells without causing the actual disease. This prepares the body to fight off a future infection.

The level of immunity can vary depending on the disease, the individual's immune system response, and the time elapsed since infection or vaccination. Herd immunity, also known as community immunity, occurs when a sufficiently large proportion of a population is immunisoituja, making the spread of disease from person to person unlikely. This protects even those who are not immunisoituja, such as infants or individuals with compromised immune systems.
