I got sick with the Wuhan Whooping Gleep in June, one of the worst illnesses ever. Plaxovid got rid of it but my Wife with both boosters was sick for 3 weeks. Me? 5 days. It is NOT a cold or the flu.
Caught Covid last January. The moment found out I was exposed took Ivermectin.
Sick for one day and my only symptoms were a fever and a runny nose.
Did lose my appetite for about 5 days. (So did all my friends who were exposed when I was.)
