An illness that lasts longer than the holiday
Hepatitis A is a virus that inflames the liver. It arrives the same way typhoid does - contaminated food or water, or hands that have not been washed - and then takes two to six weeks to show itself, which is why people often fall ill after they get home and never connect it to the trip.
It does not become a long-term infection, and almost everyone recovers fully. What it does do is flatten you: jaundice, exhaustion, nausea and a complete loss of appetite, commonly for four to six weeks and sometimes for months. Adults get it considerably worse than children, and it gets worse again with age.
Why we push the second dose
One dose does the job for the trip in front of you. It is the second, given six to twelve months later, that converts a holiday precaution into cover lasting roughly twenty-five years - and at that point you are done, for most travel, for most of your adult life.
People put the second dose off because the trip is over and the urgency has gone. It is worth a note in your calendar: the gap can stretch well beyond twelve months and still work, so if you are reading this years late, come in anyway rather than starting again.
Doing it in one visit with hepatitis B
A combined hepatitis A and B vaccine exists and we stock it. It is the sensible route if you need both - fewer injections, one course to remember - and the price per dose is published alongside the single vaccines so you can see the comparison rather than take our word for it.
If you only need hepatitis A, the single vaccine is the cheaper and shorter course. We will say so.
