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.
Adults who seek protection from hepatitis B virus infection may receive a 3-dose series of single-antigen hepatitis B vaccine (HepB) (Engerix-B, Recombivax HB) at 0, 1, and 6 months. Adults may also receive a combined hepatitis A and hepatitis B vaccine (HepA-HepB) (Twinrix) at 0, 1, and 6 months.
