I need information, case studies/statistics, on hepatitis B vaccine effectiveness after repeated exposure, i.e. a married couple where 1 is chronic HBV and the other is vaccinated with positive response. I've looked everywhere I could think of and can't find anything. I think seroconversion imparts lasting immunity, but need proof to allay a hypochondriac. Any help would be greatly appreciated.
Hi and welcome. There are no doctors in here. Mainly just Hep C patients. I think once you've been vaccinated for Hep B, it will show positive on an antibody test. However, there should be some people on here soon that can give you a better answer.
The only way to monitor the effectiveness of the vaccine or your ability to produce enough antibodies to prevent infection is to be tested for the Anti-HBs "Quantitative", not "Qualitative". It measures the amount of antibody in your blood and compares it to a reference range for immunity. It has been noted that some vaccine recipients require a booster dosage after 5+ years, but I do not know the stats on this. If you are concerned, I would go get the quantitative test and a booster vaccine.
Yes, you should get tested for the antibodies. I was vaccinated for B through my job and after testing positive for HCV, my doctor tested for B antibodies, and told me the vaccine had not worked, so I am doing it all over again. Now I will be sure to get retested after completing the series to make sure this one took.
