Researchers have discovered that, during recent years, several interventions have been introduced aiming to decrease the otitis media burden -- and they've been successful. The researchers found there was a downward trend in visits from 2004 to 2011, with a significant drop in children younger than 2 years that coincided with the advent of the 13-valent vaccine, or PCV-13, in 2010.
