Shingles vaccine (ZostavaxÂ®) reduces the risk of developing shingles and the long-term pain from post-herpetic neuralgia (PHN) caused shingles. The Advisory Committee on Immunization Practices (ACIP) recommends shingles vaccine for people aged 60 years and older.here are no long-term studies showing how long the vaccine is effective in 50 to 59 year olds. In adults vaccinated at age 60 years or older, protection from the vaccine decreases within the first 5 years after vaccination.
Earth's atmosphere is about 300 miles (480 kilometers) thick, but most of it is within 10 miles (16 km) the surface. Air pressure decreases with altitude. At sea level, air pressure is about 14.7 pounds per square inch (1 kilogram per square centimeter).
Radius, diameter and circumference. The mean radius of Earth is 3,959 miles (6,371 kilometers). However, Earth is not quite a sphere. The planet's rotation causes it to bulge at the equator. Earth's equatorial diameter is 7,926 miles (12,756 kilometers), but from pole to pole, the diameter is 7,900 miles (12,720 km) â a difference of only 40 miles (64 km).
