Study Notes
- In 1796, Edward Jenner successfully administered the first-ever vaccine to an 8-year-old boy, using cowpox virus to protect against smallpox, marking a breakthrough in vaccination history.
- The immune system defends against infectious diseases by triggering responses like coughing, sneezing, inflammation, and fever to identify and eliminate foreign pathogens.
- Innate immune responses provide initial defense, while adaptive immunity involves specialized cells like B and T cells that fight and remember pathogens for future encounters.
- Vaccines work by stimulating the adaptive immune system without causing the full disease, using weakened live vaccines, inactivated vaccines, or subunit vaccines targeting specific components of pathogens.
- Live attenuated vaccines are made from weakened forms of the disease-causing agent, while inactivated vaccines involve killed pathogens, both triggering an immune response without causing full-blown disease.
- Subunit vaccines focus on specific parts of pathogens to induce targeted immune responses, while DNA vaccines isolate genes that produce specific antibodies needed to fight off diseases when injected into the body.
- Advancements in DNA vaccines offer the potential for more effective treatments against various infectious diseases in the future, paving the way for tackling diseases like HIV, malaria, or Ebola.
