What are the risks if i did not take the complete 3 dose series (i.e taken only 2 shots) of hepatitis a&b vaccines?

3 doses are required: 2 doses are better than none, but the complete 3 vaccines series is necessary to achieve an adequate level of immunity.

I agree with Dr. Lopez in emphasizing to finish full doses of vaccination. Hepatitis A vaccination is often given in 2 doses.

No immunity: Have your doctor check antibody titers.
