Public Knowledge and Opinion on Childhood Routine Immunizations in Two Major Cities of Anambra State, Nigeria.

Awareness of the term "immunization" was high although knowledge of its indication did not measure up with this awareness, especially among the less educated. Most parents, especially those who worked in tertiary institutions,r had higher income, or education, were favorably disposed towards opinions that could positively influence immunization uptake. Efforts should be intensified at improving awareness on the indication, benefits and safety of immunization, and improving public opinions in order to optimize childhood immunization.
