A recent study in open-access journal Frontiers in Immunology finds that common foods, vaccines, bacteria and viruses may all prime our immune system to attack SARS-CoV-2, the virus that causes Covid-19. These agents all contain proteins that are similar to those found in SARS-CoV-2.
Proteins present in bacteria, human cells, vaccines, and even foods may all share similarities with those in SARS-CoV-2. The researchers behind this latest study hypothesized that similarities between SARS-CoV-2 and other common proteins may affect our susceptibility to the virus.
When our body is attacked by a pathogen, such as a virus or bacterium, it launches an immune response that involves antibodies. These immune proteins stick to specific parts of the pathogen and contribute to its destruction. After the initial infection has subsided, white blood cells called memory T and B cells will retain a memory of the pathogen, or at least certain parts of its structure. These cells will be ready to mount an immune response very rapidly if they ever encounter the pathogen again.
