Definition

4:3:1:3::1 immunization coverage. Depending on the brand of vaccine used, a child would either get 3 doses of Hib plus a booster, or 2 doses of Hib plus a booster; at the state-level, the CDC no longer reports Hib simply as 3 or more
doses but instead specifies that the “full series” was received.
