The Hepatitis B vaccine series requires 3 shots and Hepatitis A vaccine requires 2 shots. The last dose in both vaccines takes place 6 months after the first dose, so some people don't get the last dose until after their travels. If you've only received a portion of the total doses required for the full series, do you get any protection? If so, to what degree?

- This question does not appear to be about traveling within the scope defined in the help center.
You could hardly be better.
According to Canadian public health agency, 95-100% of patients produce antibodies after 1 shot of Hepatitis A, nearly 100% after two shots.
Though, this does not mean you are nearly 100% immune after two shots
