How long does it take to produce antibodies after the first injection of hepatitis B vaccine?

After the body is injected with hepatitis B vaccine antibody, antibody will be produced about one month after the first injection, but the antibody titer at this time is relatively low, so it is necessary to continue to inject the second and third injections to strengthen the hepatitis B antibody in the body, so as to produce resistance to the hepatitis B virus appearing outside.
