Hi, this is my first post and I’d like to get some advice.
I have two children (6 and 3) and they have both received their first dose of vaccine and Immunoglobulin-VF at birth and completed the other 2 doses according to the Australian immunization schedule.
My eldest child had Hep B Serology blood tests done at 4 years old and here are the results :
Hep B Surface Antigen (CMIA) Not detected
Hep B Surface Ab (CMIA) 282.2 mIU/mL
Hep B Core Total Ab (CMIA) Not detected
Comment: No evidence of current or past hepatitis B infection. Immune to hepatitis B. Hepatitis B surface antibody levels of equal to or greater than 10 mIU/mL in immunocompetent patients following immunisation indicates that the person will be protected against disease. Subsequent loss of detectable antibody on testing does not mean loss of protection.
From my understanding, my eldest child is protected - Am i correct?
However, with my youngest who had blood tests done recently, the results were very different:
Hep B Surface Antigen (CMIA) Not detected
Hep B Surface Ab (CMIA) <10.0 mIU/mL
Comment: No evidence of current hepatitis B infection. No evidence of immunity to hepatitis B virus. A hepatitis B surface antibody level of equal to or greater than 10 mIU/mL is considered protective. However, if the person is known to have completed hepatitis B vaccination in the past and serologically responded, then later non-reactive antibody results do not indicate loss of protection.
From my understanding, my youngest does not have the virus but also does not have any immunity. How is this possible? My GP said that it is not uncommon for children at this age to not have any immunity detected but that does not mean they are not protected so long they have received all the required vaccines. Is this true?
We took the GP advice and gave my youngest another booster shot and will repeat the blood test in a month. I’m just getting so anxious and can’t imagine what if my youngest is a vaccine non-responder. What’s the odd? I will be living in constant fear and guilt what if my youngest has contracted the virus from me? I know logically the risk is low but I can’t help thinking the worse (I am currently on treatment for my high viral load and taking Entecavir).
Thank you for reading my long post!
