After I tested positive for covid with serious symptoms, such as extreme fired feeling and dry cough and low grade fever, all symptoms disappeared in 36 short hours. I have no way to know why I recovered so fast without any medications or hospitalization. I am suspecting the mRNA based shots had created something to kill the virus with lightening speed. It does not matter why. I am just so thankful for not ending up in a hospital.
Or it could be your system over many years had a library od details about the othe 26 key proteins that made up the virus. The spike was just 1.
