Teton Wilderness, Wyoming. Part of one of the largest contiguous wild areas in the United States, Teton Wilderness bridges the area between Grand Teton National Park and the especially remote southeast corner of Yellowstone, and is bordered by two other federal wilderness areas within Bridger-Teton National Forest.
Four doses of polio vaccine (IPV) are routinely recommended for U.S. children at ages 2 months, 4 months, 6-18 months, and 4-6 years. The first dose may be given as early as age 6 weeks.
Three hepatitis B vaccine schedules have been shown to induce levels of seroprotection of greater than 95% in infants. One schedule uses an initial dose administered at birth, followed by doses at 1 and 6 months of age. The next schedule has doses given at 2, 4, and 6 months of age.The third schedule is for vaccine given at 6, 10, and 14 weeks of age.nce again, the vaccine schedule of doses given at 6, 10, and 14 weeks has seroconversion rates identical to schedules with longer intervals between doses. There are limited data supporting long-term protection for the schedules with shorter intervals, but existing data do support this approach.
