So this is an N of 1. Daughter positive in June - showed antibodies in July. Retested for antibodies this week due to several kids at school having it. Zero. Is it because she had no symptoms antibody response was minimal? Does it still mean with out those specific antibodies that she could get reinfected or get much milder infection. Will her Tcell response be stronger? She's been our super girl since we figured she was immune.

test her again in a few weeks, they will be back up. Tcell and antibody response is of science still under study.
