I will be traveling to Asia next year. Upon getting information about my injections was told I don't need a hep A vaccine before travel.

I had my first shot of hep A in 2006 & the second 2011 both prior to traveling.

from what I understand you need 2 shots, the 2nd within the 6 months to 12 months from the first to be protected for 25 years.

Any advice would be great?
