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.
Vaccine Administration. Hepatitis B vaccine (see Table 3-04) is usually administered as a 3-dose series on a 0-, 1-, 6-month schedule to achieve immunity. The second dose should be given â¥1 month after the first dose; the third dose should be given â¥2 months after the second dose and â¥4 months after the first dose.
