The Hepatitis A vaccination is given in two doses. If given with the Hepatitis B vaccine, it is given in three doses. You need to get the second vaccination against Hepatitis A to have full immunity. It should be good for life. The Typhoid vaccine is only good for several years so if you were to travel again several years later, you may need to get re-vaccinated for Typhoid.
You will be fine, those rarely require boosters. I know Hep A for sure requires no additional work.
