Work out immunisation dropout rate instantly with clear inputs, formula shown and shareable results.
Compares first and final dose numbers to give the dropout rate, the standard indicator of whether children who start a vaccine series finish it.
Dropout rate
Dropout (%) = (first dose - final dose) / first dose x 100
Under 10% is the usual programme benchmark; higher values indicate access or defaulter-tracing problems.
Yes, if children who received the first dose elsewhere are counted for the final dose, which signals data quality problems.
