See my 25. This little boy was tested both times by his specialist at UCLA, for H1N1, the expensive test, because he has other health issues.
He really did get H1N1 twice. Who knows, maybe it was a different mutation because it was 4 months between getting it. This beautiful little boy got through it even with compromised lungs, two times. He’s fine.
Sounds like Wave 1, Wave 2. Perfect timing. Doesn't seem to be any need for genetic drift in order to be re-infected.
