Grandmother’s Hepatitis B virus replicates, grandson is 9 months old, should I take my grandson to get tested for Hepatitis B antibodies?

Grandmothers presenting with hepatitis B virus replication can take their grandchildren for hepatitis B antibody testing.
When hepatitis B virus replication occurs, it is necessary to assess the level of the number of hepatitis B virus replication, the higher the number of hepatitis B virus replication suggests that the virus replication is stronger and more contagious, and it is also necessary to assess whether the patient has hepatitis B carriers, hepatitis B triple positive, hepatitis B triple positive, hepatitis B minor triple positive, hepatitis B minor bi-positive problems, and to determine whether the value of transaminases is abnormal or not.
In general, infants need to be vaccinated against hepatitis B within 24 hours of birth, and the second and third shots of the vaccine are administered at 1 month and 6 months of age, respectively. Therefore, it is necessary to test for antibodies at this time, as some people may not have antibodies after receiving the hepatitis B vaccine.
If no hepatitis B surface antibody is found after the test, it is necessary to take hepatitis B vaccine in time, and it is recommended to consult the infectious disease department or vaccination department of regular hospitals.
