Question
Mom checked Hepatitis B two-and-a-half test and it shows 2.4.5 positive, will the child get Hepatitis B? Main symptoms: None, Onset time: At 12 years old, Laboratory test result: 2.4.5 positive.
Answer
Hello, the second, fourth, and fifth items in the Hepatitis B two-and-a-half test are the Hepatitis B surface antibody, Hepatitis B e antibody, and Hepatitis B core antibody respectively. When these three are positive, it indicates that the three antibodies are positive. This situation suggests that you have been infected with the Hepatitis B virus but have recovered. It can also be understood as recovery from an acute Hepatitis B virus infection. It is recommended that you check liver function, Hepatitis B virus DNA, and liver ultrasound to determine whether there is viral replication. If liver function is normal and there is no viral replication, you can rest assured. You are just like a normal person and do not need to receive the Hepatitis B vaccine injection to increase antibodies; theoretically, there will be no recurrence. In other words, if all the above indicators are normal, it means that the Hepatitis B virus has been completely neutralized and removed from the body. Unless the Hepatitis B virus mutates, it will not be reinfected. Since the antibody titer produced by the infection with the Hepatitis B virus is high and lasts a long time, its duration is equivalent to lifelong immunity. In such cases, this will not affect newborns. Infants can receive the Hepatitis B vaccine normally; one dose of the vaccine is injected at birth, followed by another dose one month later and another one at six months later, totaling three doses; this schedule is called the 0-1-6 scheme. Now, most newborns are implemented planned immunization and receive free vaccinations at birth, which can basically ensure that they will not get Hepatitis B in the future. For children, it is generally necessary to do another two-and-a-half test before enrollment to see if there are antibodies; if there are no antibodies, a booster shot should be administered again. If all your indicators are normal, breastfeeding is not a problem and can be done directly.
