Infant Hepatitis B Vaccination: Whole Process, Precautions and Vaccination Significance

Infant hepatitis B vaccination is a matter of great concern to every parent. Before vaccination, you must first understand the baby's antibody situation. From antibody detection to vaccine selection, this paper will introduce the whole process of baby's hepatitis B vaccine in detail.

Antibody detection

By testing for two and a half days, it can be clear whether the baby has produced hepatitis B antibodies. If the antibody is positive, it means that the baby's immune system has the ability to recognize hepatitis B virus, and there is no need to vaccinate again at this time.

If the baby's test result is negative, that is, there is no antibody, you need to be vaccinated with hepatitis B vaccine. It is usually necessary to inject three shots of vaccine, and then test two and a half shots after vaccination to ensure that the baby has successfully produced antibodies.

age limit

For younger babies, their immune system is not yet fully mature, so it may be difficult for them to stimulate the body to produce corresponding antibodies before they are three to five years old. But by the age of three to five, the baby's immune system is gradually improved, and it is easier to produce antibodies after vaccination.

Age change

At the age of twelve, a baby's immune system is equivalent to that of an adult. If the test results show that the antibody still exists, it means that the baby's immune system has a perfect ability to recognize hepatitis B virus. On the other hand, if the baby fails to produce antibodies after vaccination, it may be meaningless to vaccinate again.

Inoculation significance

To sum up, hepatitis B vaccination is not simply to permanently produce antibodies, but to improve the baby's immune system attributes and improve the defense ability against hepatitis B virus. When choosing whether to vaccinate, parents should fully understand the baby's antibody situation and make wise choices according to the actual situation.
