I look at hbv like chicken pox. As adults, you can contract, your body fights it (flu like symptoms) and then builds antibodies and you’re protected for life. But as children, the immune system is not strong yet, that’s why infants and kids up to 5, have a 90% chance of being chronic.
You can try Reishi mushroom, raw honey mixed with tumeric as a tea and drink daily on an empty stomach. All three has anti viral properties.
