The Polio guidelines are different, with the U.S. requiring 3 shots early (as opposed to 2 in Japan) and one at 4-6 years old, whereas Japan makes no recommendation of a Polio vaccine beyond 18 months.
All infants younger than 24 months should receive four doses of the vaccine, the first one at 2 months. The next two shots should be given at 4 months and 6 months, with a final booster that should be given at 12 to 15 months. Children who do not get their shot at these times should still get the vaccine.
