Prevnar 13 was approved by the U.S. Food and Drug Administration on February 24, 2010. After waiting for the outcome of a trial underway in the Netherlands, the Centers for Disease Control and Prevention (CDC) recommended the vaccine for adults over age 65 in August 2014.
In 2011, the US Food and Drug Administration (FDA) approved PCV13 for use in adults â¥50 years of age [6], and, in 2016, they expanded the approved age range to include adults 18 to 49 years of age [7]. It is important to note, however, that approval by the FDA is not the same as recommended use.
