Vaccinations have a strong immune stimulating effect with the goal to produce high levels of IgG antibodies against the selected virus or bacteria. Some individuals react violently to such vaccinations. It is highly probable that in such cases unspecific bindings occur and lead to unspecific IgG positive reactions in the ImuPro test. We therefore recommend keeping a time gap of at least 9 months between the vaccination and the blood drawing for the test.
