Doing tests for antibodies following vaccination is not recommended, as there are no reference marks to evaluate the results. Wish you good health!

You did not mention how long after the vaccination that the antibody tests were drawn...or why you had them drawn. The values you quote apparently do indicate some activity but the clinical significance would have to be based on a good knowledge of the test and normal values. I recommend you discuss the tests with the physician who ordered them.
