The second dose of hepatitis B vaccine timed out.

Hello, the injection procedure of hepatitis B vaccine is 0- 1 month -6 months, that is, when the first needle is injected one month later, the second needle is injected.

Suggestion:

It is nearly two months before the first vaccination. You can inject the vaccine now, inject the third injection four months later, and then do five hepatitis B tests to see if the hepatitis B surface antibody is positive. If it is positive, it means that the vaccine is effective and immune to hepatitis B virus.
