Hi everyone, it’s me again, here is something I feel like I need to ask or maybe I just being OCD. Let me go straight to the story.
My mother-in law who tested negative for HBV in June 2024 had held and kissed my infant son on his forehead when he was 1 month old on September 21, 2024. My son received his 1st HBV vaccine dose when he was 1 day old.
The thing that got me thinking was because my father-in-law who was tested positive for HBV back in July 2024.
My thinking is that what if my mother-in-law contracted HBV from my father in-law after July 2024, and my son who only received the 1st dose for about 4 weeks might not developed enough immunity yet.
In addition, later in the day I saw my son has a scratch on his cheek.
My question is what is the possibility of exposure for my son in this case? because later in the day when my wife applied eczema cream on his face. I saw he has a scratch on his cheek. I mean can my wife smear the virus from his forehead to the scratch and expose him?
Dear @Jason2024,
The likelihood of exposure through this route is negligible. Remember that infection can be prevented by vaccination even after the exposure from HBV-positive mothers during birth where much more fluid is exchanged.
Hope this helps,
Thomas
thank you so much Dr. Tu
