We took my LO to an allergist because he has constant sinus infections. They did a scratch test and DH and I were shocked when he didn't react to a thing. The allergist wanted blood work done and the results came back that generally kids have 14 pneumonia titers and he only has 4.

So, we have to go get an specialized vax because even though he is vax'ed against pneumonia, LO isn't immuno-compromised which could be why LO is sick so often. We'll go back for another blood draw about a month after the vax to see if he has more titers.

Has anyone has experience with something like this?

No vax debates please!
