I've noticed some of my more paranoid relatives were getting vaccines because they worked in hospitals. I would visit my Grandparents for the holidays where these two would be there with their two kids on at least two occasions. I got sick both times. Grandpa went into a coma with a fever after one of their visits and he later died. Grandma moved to be close to an aunt and died of heart failure within the year. Since then, I've had no contact with the family as there are no more holiday visits. I've not been sick since then with the flu. I think the vaccines spread the flu.
