Death of my nana

My nana (albeit elderly) died I believe after having her 2nd covid jab. I saw her on the 24th June and I noticed a slight difference in her. By the next week she was delirious, had been nauseous and vomitting, body aches and on the 5th July we lost her. I was told by a resident nana was the 5th person to pass that week (I saw the hearse twice there whilst we spent the last 2 days with nana) and there were 2 other resident deaths after nana. It cannot be a coincidence!
