Your body can get antibodies from what
Your body can get antibodies from various sources:
1. Natural immune response: When your body is exposed to a pathogen (e.g., virus or bacteria), the immune system recognizes it as foreign and produces specific antibodies to fight against it. This process is called natural immunity.
2. Vaccinations: Vaccines contain weakened or inactivated forms of a pathogen or its proteins. When you receive a vaccine, your immune system recognizes these foreign particles and produces specific antibodies to neutralize them. This creates immunity against that particular pathogen, so if you are exposed to the actual pathogen later, your body can quickly produce the specific antibodies to fight it off.
3. Passive immunity: In some cases, you can receive ready-made antibodies directly from another source. For example, infants receive antibodies from their mothers through the placenta during pregnancy and from breast milk after birth. This passive immunity provides them with temporary protection until their own immune systems mature.
4. Blood transfusions: In rare cases, blood transfusions can be used to provide specific antibodies to patients who have a weakened immune system or specific medical conditions. This is called immunoglobulin therapy.
It's important to note that antibodies are specific to the pathogen they are produced against. They play a crucial role in protecting your body against infections by recognizing and neutralizing the pathogens.
