These are general thoughts/questions (not researched):
In high endemic areas, shouldn't we have some stats by now, on protection afforded by the vaccines, as the mothers reach childbearing age?
My understanding is that you can separate vaccine protective status from natural infection immunity?
Is the emphasis so strong, on vaccinating children/infants at extremely low risk, that the areas or populations with high infection rates are not even being reached?
Has there been mutation in the hep b strains?
posted above, I looked around a little last night. What I found was not reassuring but as you know this takes hours and hours
to feel like you have a really good understanding. That post, (viral load) also made me wonder about this "dried blood," capable of transmitting infection for up to a week, stuff. That seems like scare tactic, total BS, imho. Yes, dialysis centers should have measures for protection in place and mothers who may take infants to places where people are sharing needles or are earning their $ in the sex industry, should be warned. You also should not let your child use an infected persons razor or toothbrush. Blood to broken skin barrier or mucosal micro abraded surfaces seems to be the danger, not saliva.
Here's one that touches on vaccination in the mothers but seems to give no useful information on how this is playing out with protection for infants? PDF is paywall protected, so ....?
With the universal administration of HB vaccine, anti-HBs conferred by HB vaccine can be found increasingly in pregnant women, and maternal anti-HBs can be passed through the placenta. This study was designed to evaluate the effect of hepatitis B immunization on preventing mother-to-infant transmission of HBV and on the immune response of infants towards HB vaccine.
