How soon before I travel should I get a hepatitis A vaccine?

ANSWER

If you're planning a trip to a place where there are outbreaks of hepatitis A, keep in mind that the vaccine only starts to work 2 to 4 weeks after you get it. And if you want long-term protection, you'll need a follow-up shot 6 to 12 months later. If you didn't get your hepatitis A vaccine a month before you travel, you may be able to get a shot of hepatitis A immune globulin before you leave. This may prevent hepatitis A infection if you get it within 2 weeks before or after you come into contact with the virus.
