 ====== CVX ======
-===== CDC Vaccine Administered CVX (NCIRD) =====
+**CDC Vaccine Administered CVX (NCIRD)** is a coding system for a vaccine substance administered. The codes are used for immunization messages and it is a product of the Centers for Disease Control and Prevention (CDC). CVX includes approximately 200 active and inactive vaccine terms. It also indicates a vaccine’s current availability and the last update time for the vaccine code. Inactive vaccine codes allow users to transmit historical immunization data.
