Study Notes
- Research suggests natural defenses against common cold may offer protection against Covid-19.
- A small-scale study published in Nature Communications involved 52 people living with someone who had Covid-19.
- Those who had developed a "memory bank" of specific immune cells after a cold were less likely to get Covid-19.
- Experts caution that vaccines remain key and no one should rely on natural defenses alone.
- Covid-19 is caused by a type of coronavirus, and some colds are caused by other coronaviruses.
- The study focused on T-cells, which kill cells infected by a specific threat.
- Some T-cells remain in the body as a memory bank, ready to mount a defense when they next encounter the virus.
- A third of people who did not catch Covid-19 were found to have high levels of specific memory T-cells in their blood.
- The T-cells were likely created when the body had been infected with another closely-related human coronavirus.
- Learning from the body's natural defenses could help inform the design of new vaccines.
