I want to address all the covid-deniers and tell them my story. Don't worry, it'll be very short. Last November I got a Sputnik jab - and last week I got Omicron. It's been just two days of having a "heavy" head, sore muscles, slight fever and throat cough. Then two more days of the illness recession. Very mild symptoms, all in all. Very similar to what I experienced after the jab (except back then it was three days, actually), or your regular seasonal flu. However, I know a family with a little child (3 y.o.) who caught Omicron and developed a full fledged bronchitis and now stays ill for about two weeks.
Just think of the children!
