Patient's question:
NoDoctor's answer:
Hello, there is generally no restriction on when you can do the hepatitis B two pairs of half test. If you want to check whether the hepatitis B vaccine has been successfully administered, it is recommended to wait 20 days after completing the full course of the hepatitis B vaccine before checking if it has been successfully administered. Individual differences vary, so the chances of producing antibodies differ. Generally, only 18% of people develop antibodies 2 weeks after the first injection, and this increases to 41% one month later. After the second injection, 80-90% of recipients can produce antibodies. Six months after the third injection, 96% of people will have positive antibody levels, which can remain stable for several years.
