That's called an immunization. They are extremely important in early life, despite what these anti-government 'nutjobs' have to say about them.
To them, I say this. Without immunizations (which by the way, you all received as very young children) the diseases would become more prevalent, and therefore, more dangerous. These diseases include, but are not limited to, tuberculosis, diptheria, polio, and smallpox. To think of not immunizing children against these diseases is, for lack of a better term, insane.
Humans can develop active immunity naturally through exposure to a pathogen, which triggers an immune response and the production of antibodies. Artificially, active immunity can be induced through vaccination by administering weakened or inactivated forms of a pathogen, prompting the immune system to produce memory cells for future protection against that specific pathogen.
The purpose of introducing weakened microbes or pathogens into the body for vaccination is to stimulate the immune system to recognize and respond to the pathogen without causing disease. This exposure helps the body develop a memory of the pathogen, allowing it to mount a quicker and more effective immune response if exposed to the actual pathogen in the future. This process enhances the body's ability to prevent infections and provides long-lasting immunity against specific diseases.
Sometimes they will develop mild flu like symptoms and have a low grade fever. With the weakened your body will recognize the pathogen and develop antibodies against it, so your reaction would be milder then contracting the actual illness.

Active immunity typically takes several weeks to develop after exposure to a pathogen or vaccination. This process involves the immune system recognizing the antigen, producing specific antibodies, and generating memory cells for future protection. The exact timeframe can vary depending on the individual and the type of pathogen or vaccine involved. Generally, it can take anywhere from a few days to a few weeks for active immunity to become fully effective.
No, you can't develop immunity to UTIs.
People do not develop immunity to UTI in the way that they may against, say, chickenpox or hepatitis B.
A person can become immune to an infectious disease through vaccination, which triggers the body's immune response to produce antibodies against the pathogen. Additionally, a person can also develop natural immunity by recovering from an infection, where the immune system creates memory cells that can recognize and fight the pathogen if re-exposed.
Yes, it is possible to develop immunity to HSV-1 after being infected, but the level of immunity can vary from person to person.
