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.
The committee recommended that seniors get both the Prevnar 13 and the Pneumovax 23 vaccines. As their names imply, Prevnar 13 protects against 13 types of pneumococcal bacteria, and the Pneumovax 23 protects against 23 types of pneumococcal bacteria.
