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).
Earth's orbit is the path in which the Earth travels around the Sun. The average distance between the Earth and the Sun is 149.60 million kilometers (92.96 million miles) and a complete orbit occurs every 365.256 days (1 sidereal year), during which time Earth travels 940 million kilometers (584 million miles). Earth's orbit has an eccentricity of 0.0167. Earth's orbital motion gives an apparent movement of the Sun with respect to other stars at a rate of about 1Â° per day (or a Sun or Moon diameter every 12 hours) eastward as seen from Earth.
