Reaching Zero Dose Children
An initiative to reach Zero Dose Children and Missed Communities
Zero Dose (ZD) Children
‘Zero-dose children’ (ZD) are those who have not received any basic vaccine. For operational and reporting purposes, “zero-dose children” are defined as children who have not received a first dose of Pentavalent vaccine, till one year of age. Number of Zero Dose Children is calculated as the difference between the estimated number of surviving infants and the reported number of infants (under 1 year of age) vaccinated with Pentavalent 1 vaccine.
Fully Immunized Child
A child is said to be fully immunized if child receives all due vaccine as per national immunization schedule within the 1st year of a child’s life. Operationally it is defined as children who have received 1 dose of BCG vaccine, 3 doses of DPT containing vaccines, 3 doses of OPV and 1 dose of Measles containing vaccines within the first year of life.
Partially Vaccinated/Drop-Out Children
Children who have received some vaccines but did not complete the full course of routine vaccines under national immunization schedule.
Unvaccinated/ Left-Out Children
Children who have never been vaccinated or reached (thus remaining unvaccinated). Globally, the Unvaccinated/Left-Out children have been termed as Zero Dose children and these ZD children predominantly reside in missed communities.
