The editor has a friend who was vaccinated with hepatitis B vaccine three times as required. Later, he went to work for a physical examination in the entry workplace, but found out that hepatitis B , which made him wonder, why did I still get hepatitis B virus even though I was vaccinated? I believe some people, like my editor’s friend, have completed the vaccination but did not produce antibodies. Why is this?
1. The detection method is inaccurate: This means that there are antibodies, but some places where the detection method does not advance and false negative results appear.
2. Weak immune response: The body's response to the hepatitis B vaccine is too weak, resulting in the body only producing trace antibodies and not reaching the lower limit of detection. At this time, the vaccine dose can be increased.
3. Hidden infection occurs: At this time, the quantitative condition of the hepatitis B virus can be detected, because no antibodies have been produced, it may be that he has been infected with the hepatitis B virus. , hepatitis B, two-and-half should also be checked for further examination.
4. Hepatitis B virus mutation: If this is the case, the hepatitis B vaccine can not work.
5. Immune function defects or low: This type of population is not prone to antibodies, such as patients after organ transplantation.
Therefore, when you do not produce antibodies after receiving the hepatitis B vaccine, you can give it a course of treatment. If the antibodies are still not produced, you should do the corresponding exclusion test.
