Our amazing immune system - Bert Hubert's writings
a day ago
- Viruses cannot reproduce without a host, and the immune system is over 99% effective against COVID-19, possibly up to 99.9%.
- The immune system is a highly advanced biological technology, far surpassing human-made inventions like protein recognition.
- Antibodies are produced by B-cells, which can mutate their DNA to create highly specific antibodies through an evolutionary process.
- When a virus binds weakly to a B-cell, it triggers cloning and mutation, refining antibodies over days for a perfect fit.
- Long-term immunity is established as B-cells become dormant but ready to reactivate quickly against reinfection.
