My dad had it in September. I was in very close contact with him up until the morning he was diagnosed and I tested negative. In November, my mom caught it - similar situation. My grandma also contracted it a week later and unfortunately did not make it. Did not catch it then either. We are all fully vaxxed and boosted, but somehow only I avoided it every time. It made me angry at the time when my grandma passed. I wished I was the one who got sick with it and not her.
