My son and DIL, who are not vaccinated, were exposed at Christmas 2021, within the week, they got covid.
The son had the sore throat, horrible head ache, back ache and fever with chills for a couple days. He said the back ache was the worst, no matter what pain reliever, or how much he took, it still hurt. 2 days in bed sweating and horrible back ache. Then all of that was over just a quickly as it started, then he had some congestion. After four days he said he was fine, but I could still hear congestion when I spoke with him on the phone days after he said he was better.
DIL just had fatigue, she wanted to sleep, and she had cold like symptoms with a mild head ache, but not much of a fever or chills, and no back ache. Hers took about 5 days. She works remote from home, answering calls, and worked through it.
They were exposed again a month ago. Son did not get it, she got it again, same symptoms she had before... fatigue, cold like symptoms. The person she got it from had more sever symptoms like my son had.
She felt like she got it so mild the first time that she developed little immunity, where my son had a much worse case, he had more immunity and did not get it the second time.
They were both glad they did not get the vaccine. For them Covid was less than the flu. With all the information we have now that the vaccine is causing problems, and we don't know the long term health effects it may cause. Young people really have no need for the jab.
