If the husband is a Hepatitis B carrier, get yourself tested for Hepatitis B half-pairs. If you are also a Hepatitis B carrier, there is no question of who is infecting whom. If you are negative for all five hepatitis B tests, you have to take hepatitis B vaccine, and it is recommended that you take 3 doses of hepatitis B vaccine according to the program of 0, 1 and 6. One month after the last vaccination, you can repeat the test to see whether you have produced hepatitis B surface antibody, if the antibody value is still negative, you should receive 3 doses of vaccine again, or double the amount of intramuscular injection. If the antibody value is less than 10, it is recommended to take 1-2 injections for strengthening, and it is better if the antibody value can reach over 100. After successful vaccination, the two half-tests should be repeated every year, and as long as the value of hepatitis B surface antibody is less than 10, it is necessary to inject hepatitis B vaccine again for reinforcement.
