The vice president of the United States is not subject to any term limits. Unlike the president, the vice president can serve in the role indefinitely.
Article II of the U.S. Constitution outlines the limitations on the executive branch of the government, but it does not mention term limits for either the president or the vice president. It was not until 1951, with the passage of the 22nd Amendment, that the two-term limit for president became law. The amendment does not limit the vice president's term, however. While a vice president can theoretically serve indefinitely, no vice president has ever served longer than two terms.
