Properly stored, raw potatoes will last for 1 to 2 weeks at normal room temperature. To maximize the shelf life of potatoes, store in a cool (45-55Â° F; warmer than the refrigerator, but colder than normal room temperature) dark area; under those storage conditions, potatoes will last about 2 to 3 months.
Postexposure Prophylaxis. Travelers who are exposed to HAV and who have not received hepatitis A vaccine previously should be administered 1 dose of monovalent hepatitis A vaccine or IG (0.02 mL/kg) as soon as possible, ideally within 2 weeks of exposure.
The accelerated vaccination schedule calls for vaccine doses administered at days 0, 7, and 21â30; a booster should be administered at 12 months to promote long-term immunity. A combined hepatitis A and hepatitis B vaccine can also be used on the same 3-dose schedule (0, 7, and 21â30 days), with a booster at 12 months.
