I am sharing some 1st/2nd hand corona virus related information hoping that it will help others:

Around Aug. 1st, a colleague of mine received the so-called COVID-19 vaccine. Within 24 hours he had corona virus symptoms, and was infecting others. His symptoms were fairly mild, but after 18 days he is still sick.

My doctor's neighbor had a similar experience around the same time, getting the injection on a Monday, and had corona virus symptoms on Tuesday. I do not know of the duration.
