This Covid is the 7th time and 7th strain of this virus.........Corona has been around since WWII ........it has always been part of the cold viruses........
Now as the FEAR MONGERING losses steam..............studies are starting to come out that people may have already had T CELL IMMUNITY.
Let's take a quick look...........follow me.

Almost every person in the world has had some encounter with a coronavirus'
Adalja added that he was not surprised to see this T cell cross-reactivity in the study participants who had not been exposed to the novel coronavirus, named SARS-CoV-2.
"SARS-CoV-2 is the seventh human coronavirus that has been discovered, and four of the human coronaviruses are what we call community-acquired coronaviruses, and together those four are responsible for 25% of our common colds," Adalja said. "Almost every person in the world has had some encounter with a coronavirus, and since they are all part of the same family, there is some cross reactive immunity that develops."
The new Nature study isn't the only paper to suggest a certain level of pre-existing immunity among some people to the novel coronavirus.
Alessandro Sette and Shane Crotty, both of the University of California, San Diego, wrote in a comment paper published in the journal Nature earlier this month, that "20--50% of unexposed donors display significant reactivity to SARS-CoV-2 antigen peptide pools," based on separate research -- but they noted that the source and clinical relevance of the reactivity remains unknown.
Sette and Crotty wrote that "it is now established that SARS-CoV-2 pre-existing immune reactivity exists to some degree in the general population. It is hypothesized, but not yet proven, that this might be due to immunity to" common cold coronaviruses.

Why some people who haven't had COVID-19 might already have some immunity
The immune systems of some people who have not been exposed to the novel coronavirus could have some familiarity with the pathogen -- possibly helping to reduce the severity of illness if that person does get COVID-19, a new study suggests.
