This is really interesting to me because I was born with Agammaglobulinemia, which is basically very low immunoglobulins. People with this usually receive IgG replacement therapy and should not receive live vaccinations as they can contract that disease.

These kids are severe hypoagammaglobulinemia, I wonder what treatment they have received for this and if they were ever given any vaccines.

If they have never gotten vaccines and received IgG replacement therapy could that maybe explain why they have not contracted anything major?

When was younger I always thought that the therapy would help with diseases such as Aids.....
