Hib cases are pretty much gone where vaccination has been done, but at this point NTHi (and to a lesser degree, Hia) have just filled the niche and the total number of cases is about the same as it was pre-Hib vaccine.

Anyway...his geneticist, who is very pro-vaccine (even though the research pertaining to my son's specific genetic syndrome supports that vaccines should be given "with caution" and that live virus vaccines should be avoided) really urged me to vaccinate him against HiB. I said "why? B strain doesn't circulate like it used to, and instead NTHi is much more common, hence my son's infection." He just kept saying over and over how it used to make so many babies sick...
I get that, I do, but the fact is that it's rare, and has been replaced with the strain my son had.My son sees an Infectious Disease specialist because of his primary immune deficiency, and he also is very pro-vaccine, but has admitted to me that he's seeing MANY more HTHi infections than he ever did before, and that many of them are becoming invasive and difficult to treat. But he's still quick to say that he still recommends HiB because "that strain was particularly virulent, and we don't want it coming back."
