hi dr.

what number is considered sufficient for titers for Hep B vax demonstrating protective immunity? does this number fluctuate? immediately after vax, what should this number be to show immunity to virus? thanks...

Response from Dr. McGovern

When your blood is tested for antibody, a titre of antibody is reported. Usually the number is accompanied by a comment from the laboratory as to whether the level of antibody is protective or not.

The actual number varies with age. Younger children have much higher antibody responses than adults. Obestiy, heaving smoking and immunodeficiency can lead to lower levels. Once the level is less than 10 international units/ml, then protective immunity has declined.
