We have noticed something interesting transpire as we have watched this virus go through the children in our household. There are three young children which live here - my almost 5 year-old, my 4 month-old and my 4 year-old grand-daughter. My two daughters have never been immunized - my grand-daughter has had every immunization possible. Out of the three, she is by far the sickest and it has lasted much longer for her. Kaylee, even with her heart problems, has pulled out of it. Allie went down for two days. Autumn, my grand-daughter, was the first to go down, has been the sickest and is still coughing, congested and running fevers. Not a very large test-group, I know, but interesting, just the same.
