The pain usually lasts for a months; however, for some people, the pain can last for years called postherpetic neuralgia (PHN) which is known as the most common complication of shingles. According to CDC, Shingrix is a new shingles vaccine licensed by the U.S. Food and Drug Administration (FDA) in 2017. Shingrix provides strong protection against shingles and PHN and is the preferred vaccine over Zostavax®, a shingles vaccine in use since 2006.
