This spike protein is what the virus uses to enter human cells.
Once administered, the vaccine introduces this genetic material into human cells. The cells subsequently produce the spike protein, which triggers an immune response. This process effectively teaches the immune system to recognize and combat the actual virus without the risk of complete infection. The use of viral vectors allows for a strong immune response, making it a vital component of the vaccine's effectiveness.
Immune Response Activation
Immune response activation is the next step in understanding how the AstraZeneca vaccine provides protection. After the introduction of the spike protein, the immune system begins to react. Two critical components of this response are the production of antibodies and the activation of T cells.
- Antibodies are proteins that bind to the spike protein, neutralizing the virus and preventing it from entering cells in the future.
- T cells play a vital role in recognizing and eliminating infected cells.
Through these mechanisms, the vaccine not only prepares the immune system for potential future encounters with the virus but also creates a memory function. This means that if a vaccinated person ever encounters the actual SARS-CoV-2 virus, their body can respond more rapidly and effectively.
