Patient's question:
Baby born and up to 6 months, received three doses of hepatitis B vaccine, but lab results showed only a slight effect, so considering an additional three doses. Which is better: domestic or export products? What kind of assistance is needed: additional vaccination, domestic or export products?Doctor's answer:
The complete course of the hepatitis B vaccine requires 3 shots, following the 0, 1, 6-month schedule, which means after receiving the first shot, the second and third shots are administered 1 and 6 months later, respectively.Advice: Your situation is also quite common. Some people do not develop antibodies after vaccination, requiring an increased dose for subsequent shots. However, for some individuals, due to hereditary factors, they still cannot produce antibodies even after multiple high-dose vaccinations. In some cases, antibody development is delayed, a condition known as a slow response.
