People who are not infected with COVID may be the key to killing the virus
(WXYZ) —According to the Centers for Disease Control and Prevention COVID data trackerMore than half of Americans may have avoided getting infected with the coronavirus.
Scientists say that anyone who has never caught COVID-19 may hold the key to defeating it.
There is evidence to suggest that some people may have what is called “hyperimmunity.” That is, their bodies appear to be naturally resistant to the virus, and immunity does not go back to vaccination.
Currently, this type of innate immunity is considered rare. However, it is important for scientists to study these cases. It is necessary to understand why some people can avoid the infection, as the answer can shed light on how to defeat this incredibly contagious virus.
This is a good example. British researchers followed a group of health care workers early in the pandemic. Some of those workers cleared the virus from their system fairly quickly, even before their bodies made antibodies to fight off the virus.
Scientists have investigated why this happened and found that exposure to the previous seasonal cold virus played an important role, probably because T cells provided cross-protection. T cells are produced by our immune system and our body makes them to help prevent the spread of the infection.
T cells may not have recognized the new coronavirus SARS-CoV-2, but may have recognized the genetic portion of the previous seasonal coronavirus, which is also contained in the new virus behind the pandemic. There is a sex.
If T cells can detect and repel different parts of the coronavirus, scientists will study how this happens and vaccine by targeting the same parts of the virus that the T cells are targeting. There is a possibility that it can be improved.
Currently, our T cells produced by the COVID-19 vaccine or due to COVID-19 infection are actually targeting the viral spike protein.
Therefore, if our vaccine can attack the internal mechanisms of the virus rather than the peplomer, it can prevent infection more efficiently and prevent infections from all future coronaviruses. Hopefully there are companies working on new single shots that will provide this wider protection.
In the meantime, it is important that people are vaccinated and boosted, and if they are over 50 years old, consider a second booster. Our numbers may still be small, but there is definitely one thing we know. That is, the virus is very unpredictable.
