You can get it from vaccines.
passive and active immunity
Active immunity can be acquired through natural exposure to an infectious agent, which triggers the body's immune response to produce antibodies. It can also be acquired through vaccination, where the immune system is exposed to a weakened or inactivated form of the pathogen, leading to the production of antibodies without causing illness.
Active immunity can be gained through natural infection, where the body produces antibodies in response to exposure to a pathogen. Alternatively, it can be acquired through vaccination, which introduces a harmless form of the pathogen or its components, prompting the immune system to generate a protective response without causing the disease.

Active immunity can be acquired through natural infection or vaccination. In natural infection, the body is exposed to a pathogen, allowing the immune system to respond and create antibodies. Vaccination involves introducing a harmless part or a weakened form of the pathogen, prompting the immune system to generate a protective response without causing the disease. Both methods lead to long-term immunity against future infections by the same pathogen.
