The correct answer is "all of the above."
Your body can produce antibodies through:
- Immunizations - Vaccines stimulate the immune system to produce antibodies against specific pathogens.
- Being exposed to the virus or pathogen - When your immune system encounters a virus or bacteria, it can respond by creating antibodies to fight it off.
- Having your immune system make it - This refers to the body's inherent ability to create antibodies in response to infections.
Thus, all these methods contribute to the body's ability to generate antibodies.
