10.2.3  Calculating the number of un-immunized infants

You should also calculate the annual number of un-immunized infants — i.e. eligible infants who have not completed any of the scheduled immunizations. You do this using the following equation:

• number of un-immunized infants = target population – fully-immunized infants, where:

• target population is the total number of eligible infants in the target age-group for immunization (under one year)
• fully-immunized infants is the number in the target age-group who have received all doses of all the EPI vaccines.
